I'm working on classical simulation of quantum computers using tensor networks. Basically trying to push the frontier of quantum advantage / supremacy from the classical side.

BSC is fun due to its interdisciplinarity. I do quantum and HPC, but I have friends working on iron deposition on the seas (i.e. climate change), nuclear fusion simulations of a tokamak, large scale scientific visualization, protein folding and synthesis, ...

The European Chips Act is also coordinated from there so there is a ton of people working on hardware design (specifically RISC-V).

> The European Chips Act is also coordinated from there so there is a ton of people working on hardware design (specifically RISC-V).

@mofeing I've seen openings regarding this and was super interested. Any ideas where I can find more info about the project / work that's being done?

I don't know much more, but I've found the following projects at BSC that are currently active around the European Processor Initiative.

- European Processor Initiative: Specific Grant Agreement 2 https://www.bsc.es/es/research-and-development/projects/epi-... - RISC-V for cloud services: https://www.bsc.es/es/research-and-development/projects/rise... - eProcessor: https://www.bsc.es/es/research-and-development/projects/epro... - DRAC: https://www.bsc.es/es/research-and-development/projects/drac...

Thank you thank you!

BSC headcount grow 500+ people in 2 years thanks to EU funds. Because the government does not know where to spend them.

What will happen after 2025 when NextGeneration EU funding ends?

This is not true. BSC had already a growing trend before the pandemy. In 2020-2021, before any EU fund, almost 200 new people were hired.

Why are you harsh? Science is a good investment and BSC has proven to be a research center where a lot of quality research is done.

Anyway, there are many plans to continue growing beyond the NextGeneration EU funds, which usually the steering committee explains on the yearly anual meeting. Keep in mind that "growing" does not always mean to grow the amount of people in a research group, but to try to create new research groups to keep it stable.

> Why are you harsh? Science is a good investment (...)

Like any high-risk investment, science is a good investment because sometimes one out of N researchers is able to have meaningful output, while the remaining N-1 barely manage to justify their existence. This might be a easy risk to take for those who take in funding, but it is also has negative tradeoffs for society in general and researchers in particular.

Think for a minute about research candidates and their careers. They are admitted as researchers fresh out of college, they spend years doing hard intellectual work on subjects with little to no relationship with industry in an environment which arguably makes you even less suited to work in industry, their livelihood in the short term becomes dependent on their institution's ability to attract funding and in the long term depends on some research institutions opening tenured positions.

Look at BSC. Do you think there will be 500 tenured positions being opened in the next decade for these researchers alone? And these are the guys already in the pipeline. 300 tenure positions per year is unthinkable. More will enter it next year, and the next year, and the next year, etc. What's your plan for these people? How do you expect them to enter the job market?

Academia is a meat grinder that's fed by graduates and spits them out, most of the time with nothing of value in terms of relevant skilsets and professional experience, and dumped onto the job market already with an age band that's incompatible with entry-level positions.

In the meantime, the money spent on these research positions could be used elsewhere. A low/mid density residential building costs around 1 million to build, and houses a dozen families or so for life. God knows Barcelona is experiencing a major housing crisis. Is this a good tradeoff?

How do you classify this as a good investment?

> This is not true.

Pretty much all BSC activities are EU funded.

> Why are you harsh?

Where is the harshness? Asking “What’s the plan when the gravy train stops?” Is a perfectly valid question.

> Science is a good investment

Some science has been a good investment. Most (especially public funded, particularly in Spain) has been a very poor investment. As an obvious example, the new accelerator CERN is pushing for will have an atrocious ROI, just like most money spent on space exploration.

We should not be taxing blue collar workers so that middle class “scientists” can call dibs on historic milestones.

> Pretty much all BSC activities are EU funded.

Depending on the department, about half of the private investment can be up to 50%.

> Where is the harshness? Asking “What’s the plan when the gravy train stops?” Is a perfectly valid question.

I'm pointing to the other comments. I also try to answer question in the last paragraph.

> Some science has been a good investment. Most (especially public funded, particularly in Spain) has been a very poor investment.

In _general_, science is a good investment. I don't agree that there have been poor investments in Spain. Do you have numbers or reports about that?

Most cases I know are that in Spain the Big Crisis cut investment and getting stable long-term fundship is almost imposible, which makes scientists' situation very unstable. And you need long-term investments in science to make returns.

> As an obvious example, the new accelerator CERN is pushing for will have an atrocious ROI, just like most money spent on space exploration.

It's not obvious to me. The LHC and space exploration have had huge indirect returns from the technology designed around it.

do you happen to be working in CUCO?

No, but some colleagues do. Also, I think some of my simulation software will start to be used by the project.

galcerte 953 days ago

Ah cool, will it be open sourced?

I'm on that project myself, we are also dealing with simulating circuits, buuut I feel like we could improve our approach somewhat lol. For example, we had a bunch of trouble trying to speed things up, I immediately thought of trying to make most things run on a GPU but we quickly found out that our circuits just have too few qubits to be parallelized decently.

More importantly, I am not very optimistic (to say the least) about the short- to medium-term real-world applications of quantum circuits we are looking into (we do time series classification, which is quite removed from other domains which work better on these computers), and I got the same feeling from the literature. Should I be feeling differently?

I just happen to be visiting Barcelona for a few days. Is it possible to visit the BSC?

Any other nerd recommendations that can spare me from yet another Passeig de Gracia walk?

Yes, but you must contact through a form or get someone from inside to show it to you. Unfortunately, I'm out of town til next week so I cannot offer it myself. Check out https://www.bsc.es/discover-bsc/visit-our-supercomputer

If you want to visit some other nerdy places, I suggest you to visit: - CaixaForum: cool science museum - Observatori Fabra: a very old telescope (no longer used for science) but has cool views of the city

These days there is a very cool interactive AI exposition at CCCB. I really recommend it.

santiagobasulto 953 days ago

Awesome, thanks! Just submitted the form, hope I’m lucky to see it before leaving.

If the guide is not available just DM me one or two days before you arrive. Any BSC staff can give a tour to a small group. But it is necessary to schedule ahead and avoid events/other tours.

You can also visit the luminous click on Via Laietana. It is old, free (on the sidewalk), but interesting.

You can enter any library to browse. Abello library in Les Corts hosts the Asimov Foundation collection. I think the Sagrada Familia library has the scientific illustration collection, etc.

I remember seeing a really old elevator in the Gòtic neighborhood... I can't remember the name of the museum where it was but it was at the museum entrance (you can just walk in and have a look).

You can also walk in most campi like UPC, UB, etc. They have some exhibitions and also panels with history of the uni and faculties. As well as libraries too.

Have fun!

good luck and have fun!

Wow, thanks very much! We're leaving tomorrow, but I'm gonna check these out in my next visit.

A little outside of Barcelona, you can (sometimes) visit a particle accelerator.

The Labyrinth of Horta. It's a bit far away from the center but there's a metro station close.

https://contrataciondelestado.es/wps/poc?uri=deeplink%3Adeta...

The quantum computer is corruption. They created an spin-off where some management guys have shares on the company. Then launched a procurement. Only the spin-off company went for the procurement and won.

This was paid with European Funds and is illegal.

personomas 953 days ago

Sounds about right here in Europe. At least they have something to show for it this time, I guess? I mean, assuming they created the quantum computer with the EU funds.

wtf are you talking about? I know people from both sides and can assure you that the whole process was done transparently and legally. The external board which selected the winner proposal did a blind review (they only knew the proposals, not who made those proposals).

It's true that Qilimanjaro is a spin-off of BSC, but they are the only company in Spain that can fabricate quantum chips. Furthermore, the chips are fabricated by Quantware and IQM, while Qilimanjaro provides the testing, calibration and service. One of the requirements from the European Funds is that the providers must be European companies. There are not many fully european companies that fabricate digital quantum chips, I'm afraid.

If you have doubts about the legality of the process, I welcome you to contact the coordinator of the project.

You might be right.

Just open the document named "Informe de valoración de los criterios de adjudicación cuantificables mediante juicio de valor" in the link above.

It is digitally signed by Juan José García Ripoll, an expert that should not have any conflict of interest.

https://web.archive.org/web/20220521122845/http://quantic.bs... (The website was removed) So it was a collaborator. And the team leader was Artur Garcia.

Oh! Wait! Artur is a co-founder: https://www.qilimanjaro.tech/team/

What a plot twist hum!

So they knew each other. And instead of doing this from a BSC salary they launched an spin-off and then sold their work to the BSC being part of BSC while he was working 50% of his time for BSC and therefore being a public employee and having an incompatibility.

You obviously do not understand tenders and also have a bad faith in addressing this message towards me (García-Ripoll) and Artur.

First of all, this tender only received one application. There could have been other applicants as it happened in Galicia's quantum computer tender, but there were none.

Second, this application was done by a collective of companies of which Qilimanjaro is only one more participant, responsible for calibration and integration.

Third, my role as scientist in this evaluation was only to certify that the specifications of the tender proposal follow the scientific requirements of the call, and whether any parameter is below or above the requested standards. That is tickboxing essentially and with only one applicant this does not influence the outcome.

So I am asking you to retract these accusations as I am concerned, or follow suit if you have so much evidence of wrongdoing.

YOU obviously don't understand tenders. You can not create your own company inside a public company and then give then money by running a procurement.

1. They knew about the tender before it was public (illegal) 2. Conditions for procurement were adjusted for this company (illegal) 3. Qilimanjaro needs experience and at least 3 contracts of the same nature fullfilled correctly. (Irregular) 4. They did NOT go in UTE (temporary union of companies) and the subcontracting was NOT declared (illegal)

I have more and more points

mercacona 953 days ago

I have nothing to do with this fight, other than being Spanish myself. But it deeply bores me that it has occurred.

I don't care who is right, truly. What bothers me is that this isn't the appropriate forum, the unbearable idealism of the accusation, the unnecessary defense, the veiled threats, etc.

What really burns me is that we are always like this… Me tuvo que tocar un país de patio de colegio.

Before answering, I want to be honest and state that Artur is my supervisor, so I might be biased. Now that I've said so...

1. Artur doesn't have an incompatibility, he asked for permission to the ministry and he works his daily 8h (sometimes more) at BSC. After that he works at Qilimanjaro.

2. Juan José García Ripoll has nothing to do with Qilimanjaro. He has his own company (Inspiration-Q).

3. Juan José was a collaborator many years ago.

4. You would be amazed to see how small is the quantum world. I've already met many of the top researchers just by moving around, because everyone knows each other. So by that logic, no one would be free of conflict. Of course they knew each other. Every one knows Juan José. Many measurements are taken to prevent favor treatment in these situations.

5. Juan José was an obvious expert to have in the external board. I dare to say that very few physicists in Spain have a CV equiparable to his (https://quinfog.hbar.es/wp-content/uploads/2020/09/CV_Juan_J...).

6. We removed the website because it was no longer being updated.

I've seen from your comments that you have been falsely accusing without any info from the inside and that all you want is to harm all the effort done by these amazing people to make progress in science in Spain. So I will stop answering your comments. I don't know where this hate comes from, but I invite you to introspect.

If anyone reading the comments gets dubious about the process, I invite them to visit the link provided above to check all the documents of the procurement and to get in contact with the project coordinator. The process was done cleanly and transparently, and as any legal public project, it can be checked and verified.

Ps.: It made me laugh to check all you stalked about Artur. I think nobody has done it before. Will show it tomorrow to Artur jajaja.

When you work for BSC you sign a non-compete agreement saying that you won't be selling all you learn from BSC to BSC:

Point 5.2: prohibición de aprovechamiento en beneficio propio o de terceros. Queda prohibido que el trabajador, sin consentimiento del responsable de BSC, transmita, reproduzca, destruya o utilice información referenciada en el apartado anterior para uso distinto al normal de trabajo. Del mismo modo se prohíbe estrictamente atodos los empleados y colaboradores de BSC el uso de dicha información en beneficio propio o de terceros.

Point 5.3: Cláusula de exclusividad. Queda prohibido que el trabajador realice proyectos basados en conocimientos del BSC para terceros fuera del ámbito laboral, o por encargo directo de terceras personas. Una vez desvinculado del BSC, queda prohibido que el trabajador aplique conocimientos propiedad del BSC o de colaboradores del BSC, con fines lucrativos, o al servicio de terceras empresas que los exploten económicamente.

And there are more and more
