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…

Low-Weight High-Distance Error Correcting Fermionic Encodings
Fedor Simkovic, Martin Leib, Francisco Revson F. Pereira
We perform an extended numerical search for practical fermion-to-qubit encodings with error correcting properties. Ideally, encodings should strike a balance between a number of th…

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…
