Quantum Wasserstein distance between unitary operations
Xinyu Qiu, Lin Chen
Quantifying the effect of noise on unitary operations is an essential task in quantum information processing. We propose the quantum Wasserstein distance between unitary operations…
Coherence and entanglement in Grover and Harrow-Hassidim-Lloyd algorithm
Changchun Feng, Lin Chen, Lijun Zhao
Coherence, discord and geometric measure of entanglement are important tools for measuring physical resources. We compute them at every steps of the Grover's algorithm. We summariz…
Controlled remote implementation of operations via graph states
Xinyu Qiu, Lin Chen
We propose protocols for controlled remote implementation of operations with convincing control power. Sharing a -partite graph state, participants collaborate to prep…
Quantum cost of dense coding and teleportation
Xinyu Qiu, Lin Chen
The quantum cost is a key ingredient to evaluate the quality of quantum protocols from a practical viewpoint. We show that the quantum cost of d-dimensional dense coding protocol i…
Necessary conditions on effective quantum entanglement catalysts
Yu-Min Guo, Yi Shen, Li-Jun Zhao +4
Quantum catalytic transformations play important roles in the transformation of quantum entangled states under local operations and classical communications (LOCC). The key problem…
The entropy of quantum causal networks
Xian Shi, Lin Chen
Quantum networks play a key role in many scenarios of quantum information theory. Here we consider the quantum causal networks in the manner of entropy. First we present a revised…
