For the first time, researchers at MIT, Caltech, Harvard University, and elsewhere sent quantum information across a quantum system in what could be understood as traversing a wormhole. Though this ex...
We report a free-space entanglement-based quantum key dis-tribution experiment, implementing the biased basis protocol between two sites which are 15.3 km apart. Photon pairs from a polarization-entan...
It was shown recently that entanglement of identical particles has a feature called dualism (Bose and Home 2013 Phys. Rev. Lett. 110 140404), which is funda-mentally connected with quantum indistingui...
Entanglement, the essential resource in quantum information processing, should be witnessed in many tasks such as quantum computing and quantum communication. The conventional entanglement witness met...
Not all quantum protocols require entanglement to outperform their classical alternatives. The nonclassical correlations that lead to a quantum advantage are conjectured to be captured by quantum disc...
Quantum entanglement is an essential resource in quantum information processing,which needs to be verified in many tasks such as quantum cryptography and computation. Due to imperfect detection device...
We describe a one-step, deterministic and scalable scheme for creating macroscopic arbitrary entangled coherent states (ECSs) of separate nitrogen-vacancy center ensembles (NVEs) that couple to a supe...
The Schrodinger’s cat thought experiment highlights the counterintuitive concept of entan-glement in macroscopically distinguishable systems. The hallmark of entanglement is the detection of strong co...
Without additional resources, it is often impossible to transform one entangled quantum state into another with local quantum operations and classical communication. Jonathan and Plenio (Phys. Rev. Le...
In this work we propose and analyse a scheme where the full spatio-temporal correlation of twin photons/beams generated by parametric down-conversion is detected by using its inverse process, i.e. sum...
Nonlinearity and entanglement are two important indications by which physical systems can be identified as non-classical. We study the dynamics of the resonant interaction of up to N=3 two-level syste...
Over the past few years we have built an apparatus to demonstrate the entanglement of neutral Rb atoms at optically resolvable distances using the strong interactions between Rydberg atoms. Here we re...
In this paper, we investigate the generation of continuous-variable quadripartite square cluster state of optical fields and discuss the enhancement of the multipartite entanglement of the cluster sta...
Abstract: An approach to fast entanglement generation based on Rydberg dephasing of collective excitations (spin-waves) in large, optically thick atomic ensembles is proposed. Long-range $1/r^3$ atomi...
Abstract: In the recent paper [Chru\'{s}ci\'{n}ski and Wudarski, arXiv:1105.4821], it was conjectured that the entanglement witnesses arising from some generalized Choi maps are optimal. We show that ...
