Rate-Distortion Theory for Mixed States
Zahra Baghali Khanian, Kohdai Kuroiwa, Debbie Leung
This paper is concerned with quantum data compression of asymptotically many independent and identically distributed copies of ensembles of mixed quantum states. The encoder has ac…
Rate Reduction of Blind Quantum Data Compression with Local Approximations Based on Unstable Structure of Quantum States
Kohdai Kuroiwa, Debbie Leung
In this paper, we propose a new protocol for a data compression task, blind quantum data compression, with finite local approximations. The rate of blind data compression is suscep…
The platypus of the quantum channel zoo
Felix Leditzky, Debbie Leung, Vikesh Siddhu +2
Understanding quantum channels and the strange behavior of their capacities is a key objective of quantum information theory. Here we study a remarkably simple, low-dimensional, si…
Generic nonadditivity of quantum capacity in simple channels
Felix Leditzky, Debbie Leung, Vikesh Siddhu +2
Determining capacities of quantum channels is a fundamental question in quantum information theory. Despite having rigorous coding theorems quantifying the flow of information acro…
Achieving fault tolerance on capped color codes with few ancillas
Theerapat Tansuwannont, Debbie Leung
Attaining fault tolerance while maintaining low overhead is one of the main challenges in a practical implementation of quantum circuits. One major technique that can overcome this…
Fault-tolerant quantum error correction using error weight parities
Theerapat Tansuwannont, Debbie Leung
In quantum error correction using imperfect primitives, errors of high weight arising from a few faults are major concerns since they might not be correctable by the quantum error…
