To reset, or not to reset -- that is the question
György P. Gehér, Marcin Jastrzebski, Earl T. Campbell +1
Whether to reset qubits, or not, during quantum error correction experiments is a question of both foundational and practical importance for quantum computing. Text-book quantum er…

Reducing the error rate of a superconducting logical qubit using analog readout information
Hany Ali, Jorge Marques, Ophelia Crawford +7
Quantum error correction enables the preservation of logical qubits with a lower logical error rate than the physical error rate, with performance depending on the decoding method.…

Error-corrected Hadamard gate simulated at the circuit level
György P. Gehér, Campbell McLauchlan, Earl T. Campbell +2
We simulate the logical Hadamard gate in the surface code under a circuit-level noise model, compiling it to a physical circuit on square-grid connectivity hardware. Our paper is t…
