Simplified Quantum Weight Reduction with Optimal Bounds
Min-Hsiu Hsieh, Xingjian Li, Ting-Chun Lin
Quantum weight reduction is the task of transforming a quantum code with large check weight into one with small check weight. Low-weight codes are essential for implementing quantu…

A Meta-Complexity Characterization of Minimal Quantum Cryptography
Bruno Cavalar, Boyang Chen, Andrea Coladangelo +4
We give a meta-complexity characterization of EFI pairs, which are considered the "minimal" primitive in quantum cryptography (and are equivalent to quantum commitments). More prec…

Transform Arbitrary Good Quantum LDPC Codes into Good Geometrically Local Codes in Any Dimension
Xingjian Li, Ting-Chun Lin, Min-Hsiu Hsieh
Geometrically local quantum codes, comprised of qubits and checks embedded in with local check operators, have been a subject of significant interest. A key challeng…
