Structure of quantum measurements implementable with one round of classical communication
Arthur C. R. Dutra, Ties-A. Ohst, Hai-Chau Nguyen +1
Measurements that can be implemented via local operations and classical communication (LOCC) constitute a class of operations that is available in future quantum networks in which…

Quantum memory in spontaneous emission processes
Mei Yu, Ties-A. Ohst, Hai-Chau Nguyen +1
Quantum memory effects are essential in understanding and controlling open quantum systems, yet distinguishing them from classical memory remains challenging. We introduce a convex…

Characterising memory in quantum channel discrimination via constrained separability problems
Ties-A. Ohst, Shijun Zhang, Hai Chau Nguyen +2
Quantum memories are a crucial precondition in many protocols for processing quantum information. A fundamental problem that illustrates this statement is given by the task of chan…
