Reading Juan Maldacenda’s recent paper on simulating a black hole only using quantum mechanics, not even quantum field theory.
He estimates it will take around 7000 logical qubits to simulate a black hole on a quantum computer, which is curiously roughly the same order of magnitude needed to break rsa/ec/bitcoin.
So we’re gonna need to simulate a bigger black hole to eat their black hole…
The big question is how many physical qubits is needed to have 7000 stable logical qubits. It could be millions!

here’s an interesting piece:
“(…) This scalability suggests that an error rate better than one in one million could be achieved using a distance-17 qubit array that comprises 577 qubits of suitably high quality.”
Amazing. Thanks for sharing. If interested, I talk about an internet network that works with neutrinos. Quantum stuff is the future.
What are we at qubit-wise now?
I think a thousand physical qubits? Logical qubits can require just as many physical qubits though for error correction. But this may get better with improved error correction tech. This is a hot research area that I follow closely 👀

It's a coincidence
