Relativistic corrections to photonic entangled states for the space-based quantum network

2020 · Physical Review A

In recent years there has been a great deal of focus on a globe-spanning quantum network, including linked satellites for applications ranging from quantum key distribution to distributed sensors and clocks. In many of these …

Quantum Interference between Light Sources Separated by 150 Million Kilometers

2019 · Physical Review Letters

We report an experiment to test quantum interference, entanglement, and nonlocality using two dissimilar photon sources, the Sun and a semiconductor quantum dot on the Earth, which are separated by ∼150 million kilometers. By making …

Dynamics of quantum coherence in a spin-star system: Bipartite initial state and coherence distribution

2019 · Physical Review A

We investigate the transient dynamics of quantum coherence for a system of two central spins in a spin-star environment by employing a numerical procedure based on a Laguerre polynomial expansion scheme. The dynamics of the …

Deep recurrent networks predicting the gap evolution in adiabatic quantum computing

2023 · Quantum

In adiabatic quantum computing finding the dependence of the gap of the Hamiltonian as a function of the parameter varied during the adiabatic sweep is crucial in order to optimize the speed of the computation. …

Robustness of non-Gaussian quantum nondemolition measurement induced entanglement between Bose-Einstein condensates

2021 · arXiv (Cornell University)

We study the robustness of quantum nondemolition (QND) measurement induced entanglement between Bose-Einstein Condensates (BECs). We consider an experimental scheme where two BECs are placed in the paths of a Mach-Zehnder interferometer, and a QND …
