Physical Review A 2023年 第5期107卷 052421-052421页
作者: Kohdai Kuroiwa Debbie Leung Institute for Quantum Computing University of Waterloo Waterloo Ontario Canada N2L 3G1 Department of Physics and Astronomy University of Waterloo Waterloo Ontario Canada N2L 3G1 Department of Combinatorics and Optimization University of Waterloo Waterloo Ontario Canada N2L 3G1 Perimeter Institute for Theoretical Physics Waterloo Ontario Canada N2L 2Y5
In this paper we propose a protocol for a data compression task, blind quantum data compression, with finite local approximations. The rate of blind data compression is susceptible to approximations even when the appr... 详细信息
