Multipartite entangling power by von Neumann entropy
Xinyu Qiu, Zhiwei Song, Lin Chen
Quantifying the entanglement generation of a multipartite unitary operation is a key problem in quantum information processing. We introduce the definition of multipartite entangli…
On the extreme points of sets of absolulely separable and PPT states
Zhiwei Song, Lin Chen
The absolutely separable (resp. PPT) states remain separable (resp. positive partial transpose) under any global unitary operation. We present a compact form of the extreme points…
Realization of permutation groups by quantum circuit
Junchi Liu, Yangyang Ren, Yan Cao +2
In this paper, we exclusively utilize CNOT gates for implementing permutation groups generated by more than two elements. In Lemma 1, we recall that three CNOT gates are both neces…
The construction of multiqubit unextendible product bases
Caohan Cheng, Lin Chen
The unextendible orthogonal matrices (UPBs) can be used for various problems in quantum information. We provide an algorithm to check if two UPBs are non-equivalent to each other.…
Entanglement detection length of multipartite quantum states
Fei Shi, Lin Chen, Giulio Chiribella +1
Multipartite entanglement is a valuable resource for quantum technologies. However, detecting this resource can be challenging: for genuine multipartite entanglement, the detection…
