arXiv 2019年
作者: Hadiashar, Shima Bab Nayak, Ashwin Department of Combinatorics and Optimization Institute for Quantum Computing University of Waterloo 200 University Ave. W. WaterlooONN2L 3G1 Canada
We revisit the task of compressing an ensemble of quantum states in the one-shot setting. The protocols achieving the best compression use shared entanglement that may be much larger than the original message, while o... 详细信息
