Scalable decoding protocols for fast transversal logic in the surface code

Mark L. Turner, Earl T. Campbell, Ophelia Crawford +2

Atomic, molecular and optical (AMO) approaches to quantum computing are promising due to their increased connectivity, long coherence times and apparent scalability. However, they…

Demonstrating real-time and low-latency quantum error correction with superconducting qubits

Laura Caune, Luka Skoric, Nick S. Blunt +22

Quantum error correction (QEC) will be essential to achieve the accuracy needed for quantum computers to realise their full potential. The field has seen promising progress with de…

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…

Leakage Mobility in Superconducting Qubits as a Leakage Reduction Unit

Joan Camps, Ophelia Crawford, György P. Gehér +3

Leakage from the computational subspace is a damaging source of noise that degrades the performance of most qubit types. Unlike other types of noise, leakage cannot be overcome by…

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…
