Topological squashed entanglement: Nonlocal order parameter for one-dimensional topological superconductors [PDF]
Physical Review Research, 2022 Identifying entanglement-based order parameters characterizing topological systems, in particular topological superconductors and topological insulators, has remained a major challenge for the physics of quantum matter in the last two decades.

Squashed entanglement in one-dimensional quantum matter [PDF]
Physical Review B, 2022 Squashed entanglement and its universal upper bound, the quantum conditional mutual information, are faithful measures of bipartite quantum correlations defined in terms of multipartitions.

Relative Entropy and Squashed Entanglement [PDF]
Communications in Mathematical Physics, 2014 We are interested in the properties and relations of entanglement measures. Especially, we focus on the squashed entanglement and relative entropy of entanglement, as well as their analogues and variants.Our first result is a monogamy-like inequality ...

Trade-off between Squashed Entanglement and Concurrence in Bipartite Quantum States [PDF]
International Journal of Theoretical Physics, 2021 In this article, we investigate the unitary dynamics of squashed entanglement and concurrence measures in Werner state and maximally entangled mixed states (MEMS) under two different Hamiltonians. The aim of the present study is twofold.

Squashed entanglement and approximate private states [PDF]
Quantum Information Processing, 2016 The squashed entanglement is a fundamental entanglement measure in quantum information theory, finding application as an upper bound on the distillable secret key or distillable entanglement of a quantum state or a quantum channel.

Energy-Constrained LOCC-Assisted Quantum Capacity of the Bosonic Dephasing Channel [PDF]
Entropy, 2023 We study the LOCC-assisted quantum capacity of a bosonic dephasing channel with energy constraint on the input states. We start our analysis by focusing on the energy-constrained squashed entanglement of the channel, which is an upper bound for the ...

Monogamy of Quantum Entanglement [PDF]
Frontiers in Physics, 2022 Unlike classical correlation, quantum entanglement cannot be freely shared among many parties. This restricted shareability of entanglement among multi-party systems is known as monogamy of entanglement, which is one of the most fundamental properties of

Squashed quantum non-Markovianity: a measure of genuine quantum non-Markovianity in states [PDF]
Quantum, 2023 Quantum non-Markovianity in tripartite quantum states $\rho_{ABC}$ represents a correlation between systems $A$ and $C$ when conditioned on the system $B$ and is known to have both classical and quantum contributions.

Linear growth of the entanglement entropy for quadratic Hamiltonians and arbitrary initial states [PDF]
SciPost Physics, 2022 We prove that the entanglement entropy of any pure initial state of a bipartite bosonic quantum system grows linearly in time with respect to the dynamics induced by any unstable quadratic Hamiltonian.
