Kinetics of sliding-window quantum error correction
Adithya Sriram, Charles Stahl, Aleksander Kubica +1
Practical implementations of quantum error correction (QEC) require rapid measurement and continuous processing of the syndrome information in order to prevent a backlog of unproce…
Fault-tolerant distributed quantum computing with a single nucleus per node
Yotam Vaknin, Shoham Jacoby, Shoham Jaocby +3
Distributed quantum computing interconnects small, high-quality nodes through optical links, but this architecture carries a pronounced asymmetry: in-node gates and measurements ar…
Magic Gate Teleportation: Structure, Useful Resource States, and Simpler Feedforward
Yunzhe Zheng, Allen Zang, Aleksander Kubica
Quantum gate teleportation is a key technique in fault-tolerant quantum computation that uses resource states to implement logical gates. Here, we develop a theory of quantum gate…
Optimizing quantum error correction protocols with erasure qubits
Shouzhen Gu, Yotam Vaknin, Alex Retzker +1
Erasure qubits offer a promising avenue toward reducing the overhead of quantum error correction (QEC) protocols. However, they require additional operations, such as erasure check…
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…
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,…
