Does doing this in silicon mean we may start to see mass produced qubit ICs? You'd have to keep coherence between all of the quantum circuit elements to actually have a calculation carried out properly, wouldn't you?

Perhaps this could lead to some sort of quantum FPGA equivalent within the next few years?

The answer is a solid maybe.

Like I said upthread, it all depends on quantum error correction. Right now they are below the threshold for some surface codes (note: in this context below a threshold is a good thing). However surface codes require a torus topology, and existing chip technology generally flat. They are above the threshold for topologically simple codes like Stein and Shor thus ruling them out. While their research is a step forward, what they have in their lab right this instant cannot be made into a scaleable quantum computer.

Interestingly enough, most quantum computers (both in theory and practice) are more like fpga's than like a classical CPU architecture. The general purpose qubits just kind of sit there and a quantum circuit is implemented on them with laser pulses. The only exception I'm aware of is the silicon waveguides group I mentioned up top.

Here's how I have understood QC and it's current state of engineering: A 2-qbit gate can do 2-qbit problems. A pair of 2-qbit gates can do 2 2-qbit problems at a time, not a 4-qbit problem. For Shor's Algorithm, you need n-qbit gates, where n is the size of your problem. Even if the claims of the paper are true, making n-qbit gates out of silicone is just as hard as making n-qbit gates the way they are done in physics labs.

Is my understanding of the phenomena largely within reality?

What you are interested in knowing about is Universal Quantum Gates. These are the quantum analog of AND, OR, NOT from which all other computations can be built.

In answer to your question, you are mistaken. The Cnot gate plus a few Single qubit gates {haddamard, pi/8, phase shift} are sufficent for any quantum algorithm including shors.

Also not to be pedantic but computers are made of silicon. Breasts are made of silicone.

The difference in e is then from electrified to electrifying?
