QuEra Paper Simulates Only Two Physical Qubits Are Needed Per Logical Qubit
by Brian Wang from NextBigFuture.com on (#75J0C)
Quera show 580 and 1156 logical qubits with neutral atom quantum computer simulations. April 2026 breakthrough (with Harvard/MIT) they shiow high-rate codes achieving over 50% encoding rate. They are using about ~2 physical qubits per logical qubit or better in simulations, with logical error rates in the teraquop regime. (1,152 physical 580 logical; 2,304 ...
