Quantum conditional mutual information and channel capacity
D. -S. Wang
Information measures acquire operational meaning through coding theorems. The quantum conditional mutual information (QCMI) is nonnegative due to strong subadditivity, yet a direct…
All about quantum error correction: distillation, mitigation, self-correction and beyond
D. -S. Wang
In this work, it is shown that many quantum error-manipulating techniques, such as distillation, error mitigation, and dynamical decoupling, are special cases of the most general f…
Towards transistor-based quantum computing
Y. -D. Liu, X. Xu, Q. -R. Wang +1
In this work, we propose and study in depth a universal quantum computing architecture based on a quantum construction of transistors. Our teleportation-based quantum transistors,…
LEAD: A Local Ensemble-Assisted Parallel Decoding Framework for Quantum Tanner Codes
Zhuo-Yan Xiao, Sha Shi, Chen-Peng Huang +2
Quantum Tanner codes are a recently developed family of quantum error-correcting codes characterized by favorable asymptotic performance characteristics. Despite their theoretical…
Towards Minimal Fault-tolerant Error-Correction Sequence with Quantum Hamming Codes
Sha Shi, Xiao-Yang Xu, Min-Quan Cheng +2
The high overhead of fault-tolerant measurement sequences (FTMSs) poses a major challenge for implementing quantum stabilizer codes. Here, we address this problem by constructing e…
Quantum simulation in the entanglement picture
D. -S. Wang, X. Xu, Y. -D. Liu
The notion of ``picture'' is fundamental in quantum mechanics. In this work, a new picture, which we call entanglement picture, is proposed based on the novel channel-state duality…
State-adaptive quantum error correction and fault-tolerant quantum computing
D. -S. Wang
We present a theoretical framework for state-adaptive quantum error correction that bridges the gap between quantum computing and error correction paradigms. By incorporating knowl…

X. Xu, Y. -D. Liu, S. Shi +2
In this work, we propose a general protocol for distributed quantum computing that accommodates arbitrary unknown subroutines. It can be applied to scale up quantum computing throu…
Quantum resource theory of coding for error correction
Dong-Sheng Wang, Yuan-Dong Liu, Yun-Jiang Wang +1
Error-correction codes are central for fault-tolerant information processing. Here we develop a rigorous framework to describe various coding models based on quantum resource theor…

D. -S. Wang
In this work, we develop universal quantum computing models that form a family of quantum von Neumann architecture, with modular units of memory, control, CPU, internet, besides in…
An additive refinement of quantum channel capacities
D. -S. Wang
Capacities of quantum channels are fundamental quantities in the theory of quantum information. A desirable property is the additivity for a capacity. However, this cannot be achie…
