Witnessing light-driven entanglement using time-resolved resonant inelastic X-ray scattering

Nature Communications, 2023
Characterizing and controlling entanglement in quantum materials is crucial for the development of next-generation quantum technologies. However, defining a quantifiable figure of merit for entanglement in macroscopic solids is theoretically and ...

On the Stochastic Analysis of a Quantum Entanglement Distribution Switch [PDF]

IEEE Transactions on Quantum Engineering, 2019
In this article, we study a quantum entanglement distribution switch that serves $k$ users in a star topology. We model variants of the system as continuous-time Markov chains and obtain expressions for switch capacity, expected number of qubits stored ...

Entanglement in quantum catastrophes [PDF]

Physical Review A, 2005
We classify entanglement singularities for various two-mode bosonic systems in terms of catastrophe theory. Employing an abstract phase-space representation, we obtain exact results in limiting cases for the entropy in cusp, butterfly, and two-dimensional catastrophes.

Entanglement and quantum correlation measures for quantum multipartite mixed states

Scientific Reports, 2023
Entanglement, and quantum correlation, are precious resources for quantum technologies implementation based on quantum information science, such as quantum communication, quantum computing, and quantum interferometry. Nevertheless, to our best knowledge,

Quantum Entanglement: Spooky Action at a Distance

Quanta, 2020
Quantum entanglement is an important resource in quantum information technologies. Here, we study and characterize in a precise mathematical language some of the weird and nonintuitive features of quantum entanglement.

Approximate encoding of quantum states using shallow circuits

npj Quantum Information
Quantum algorithms and simulations often require the preparation of complex states through sequences of 2-qubit gates. For a generic quantum state, the number of required gates grows exponentially with the number of qubits, becoming unfeasible on near ...
