It will take hundreds of fault tolerant qubits. That means it will take potentially millions of physical qubits of relatively high quality. There is a long road ahead from 72 relatively medium quality to millions of relatively high quality qubits.
- ByThyGrace 9y agoAs a layman, I've never heard of qubit quality. What is it exactly? How do you determine it? And why does it affect computation?
- vtomole 9y agoQubit quality is defined by the quantum volume [0]. Errors that occur when gates are applied to qubits need to be below a certain threshold to perform error correction.

- Zaak 9y agoIs quantum error correction really that demanding? I thought it was only a small multiple of the number of qubits, not orders of magnitude more.
