Quantum Channel Polynomial Processing
Tianhan Liu, Fedor Simkovic, Martin Leib
We introduce a quantum algorithmic framework based on probabilistic mixtures of unitary channels that, similar to the framework of quantum singular value transformations, enables t…

Quantum error detection in qubit-resonator star architecture
Florian Vigneau, Sourav Majumder, Aniket Rath +13
Achieving industrial quantum advantage is unlikely without the use of quantum error correction (QEC). Other QEC codes beyond surface code are being experimentally studied, such as…

Small Quantum Codes from Algebraic Extensions of Generalized Bicycle Codes
Nikolaos Koukoulekidis, Fedor Šimkovic, Martin Leib +1
Quantum error correction is rapidly seeing first experimental implementations, but there is a significant gap between asymptotically optimal error-correcting codes and codes that a…
