Fault-tolerant quantum architectures based on erasure qubits
Shouzhen Gu, Alex Retzker, Aleksander Kubica
The overhead of quantum error correction (QEC) poses a major bottleneck for realizing fault-tolerant computation. To reduce this overhead, we exploit the idea of erasure qubits, re…
Demonstrating a long-coherence dual-rail erasure qubit using tunable transmons
Harry Levine, Arbel Haim, Jimmy S. C. Hung +110
Quantum error correction with erasure qubits promises significant advantages over standard error correction due to favorable thresholds for erasure errors. To realize this advantag…
Single-shot decoding of good quantum LDPC codes
Shouzhen Gu, Eugene Tang, Libor Caha +3
Quantum Tanner codes constitute a family of quantum low-density parity-check (LDPC) codes with good parameters, i.e., constant encoding rate and relative distance. In this article,…
Lifting topological codes: Three-dimensional subsystem codes from two-dimensional anyon models
Jacob C. Bridgeman, Aleksander Kubica, Michael Vasmer
Topological subsystem codes in three spatial dimensions allow for quantum error correction with no time overhead, even in the presence of measurement noise. The physical origins of…
Protecting information via probabilistic cellular automata
Annie Ray, Raymond Laflamme, Aleksander Kubica
Probabilistic cellular automata describe the dynamics of classical spin models, which, for sufficiently small temperature , can serve as classical memory capable of storing info…
