Measuring statistics-induced entanglement entropy with a Hong–Ou–Mandel interferometer

Nature Communications
Despite its ubiquity in quantum computation and quantum information, a universally applicable definition of quantum entanglement remains elusive. The challenge is further accentuated when entanglement is associated with other key themes, e.g., quantum ...

Estimation of the Influence of a Noisy Environment on the Binary Decision Strategy in a Quantum Illumination Radar

Sensors, 2022
A quantum illumination radar uses quantum entanglement to enhance photodetection sensitivity. The entanglement is quickly destroyed by the decoherence in an environment, although the sensitivity enhancement could survive thanks to quantum correlations ...

Entanglement Availability Differentiation Service for the Quantum Internet

, 2018
A fundamental concept of the quantum Internet is quantum entanglement. In a quantum Internet scenario where the legal users of the network have different priority levels or where a differentiation of entanglement availability between the users is a ...

Comments on entanglement entropy [PDF]

, 1998
A new interpretation of entanglement entropy is proposed: entanglement entropy of a pure state with respect to a division of a Hilbert space into two subspaces 1 and 2 is an amount of information, which can be transmitted through 1 and 2 from a system ...

Terahertz‐Driven Ultrafast Dynamics of Rare‐Earth Nickelates by Controlling Only the Charge Degree of Freedom

Advanced Functional Materials, EarlyView.
The THz drive of the Mott insulating state of a rare‐earth nickelate induces instantaneous insulator‐metal transition via quantum tunneling of valence electrons across the bandgap. This transition is pure electronic and highly non‐thermal, which may find its applications in ultrafast opto‐electronics with enhanced performance and minimal device size ...

Quantifying entanglement for unknown quantum states via artificial neural networks

Scientific Reports
Quantum entanglement acts as a crucial part in quantum computation and quantum information, hence quantifying unknown entanglement is an important task. Due to the fact that the amount of entanglement cannot be achieved directly by measuring any physical

Entanglement required in achieving entanglement-assisted channel capacities

, 2002
Entanglement shared between the two ends of a quantum communication channel has been shown to be a useful resource in increasing both the quantum and classical capacities for these channels.

Quantum Quenches and Entanglement [PDF]

, 2017
A simple but quite non-trivial class of non-equilibrium processes of a quantum many-body system is quantum quenches. We start with a ground state \(\mid \!\Phi _{0}\rangle\) of a certain Hamiltonian H0. At time t = 0, we suddenly change the Hamiltonian from H0 to a new one H.
