Everybody will need new private keys.

What do you do with old coins? Satoshi's one for example? Or lost coins that nobody has the key for?

Do you set a threshold day, after which all unclaimed coins are just marked destroyed forever? If not, how do you know someone claiming some coins didn't use a quantum computer to get the key?

>Do you set a threshold day

yeah pretty much.

>What do you do with old coins? Satoshi's one for example? Or lost coins that nobody has the key for?

If those coins hasn't been touched for decades, despite widespread announcements of pre-quantum cryptography (presumably it wouldn't happen overnight), it's safe to say that nobody is going to claim them.
