Characterizing Space-Constrained Implementability of Quantum Instruments via Signaling Conditions
Kosuke Matsui, Jun-Yi Wu, Hayata Yamasaki +2
Scaling up the number of qubits available on quantum processors remains technically demanding even in the long term; it is therefore crucial to clarify the number of qubits require…

Universal classical-quantum channel resolvability and private channel coding
Takaya Matsuura, Masahito Hayashi, Min-Hsiu Hsieh
We address the problem of constructing fully universal private channel coding protocols for classical-quantum (c-q) channels. Previous work constructed universal decoding strategie…

Characterizing the Burst Error Correction Ability of Quantum Cyclic Codes
Jihao Fan, Min-Hsiu Hsieh
Quantum burst error correction codes (QBECCs) are of great importance to deal with the memory effect in quantum channels. As the most important family of QBECCs, quantum cyclic cod…
