The optimal positive operator-valued measure for state discrimination
2021 · arXiv (Cornell University)
Evaluating the amount of information obtained from non-orthogonal quantum states is an important topic in the field of quantum information. The commonly used evaluation method is Holevo bound, which only provides a loose upper bound …

Free-Space Phase-Matching Quantum Key Distribution
2021 · 2021 13th International Conference on Wireless Communications and Signal Processing (WCSP)
As a practical version of twin-field quantum key distribution (TF-QKD), phase-matching quantum key distribution (PM-QKD) is able to surpass the linear bound without quantum repeaters. Implementing PM-QKD through free space can guarantee two parties to …

Phase-matching quantum key distribution with light source monitoring
2021 · Chinese Physics B
The transmission loss of photons during quantum key distribution (QKD) process leads to the linear key rate bound for practical QKD systems without quantum repeaters. Phase matching quantum key distribution (PM-QKD) protocol, an novel QKD …

Quantum algorithm for neural network enhanced multi-class parallel classification
2022 · arXiv (Cornell University)
Using the properties of quantum superposition, we propose a quantum classification algorithm to efficiently perform multi-class classification tasks, where the training data are loaded into parameterized operators which are applied to the basis of the …
