University of Toronto physics students James Bateman (left) and Lee Rozema (right) led a study which successfully measured multiple photons in an entangled NOON state. The work paves the way for great advances in using quantum states to enable the next generation of ultra-precise measurement tech...
Energy cost of entanglement extraction: Alice and Bob have access to two parts of a quantum system in an entangled state |Ω〉AB with Hamiltonian HAB. Using local operations and classical communication (LOCC), they extract m EPR pairs into their ancillary systems A′ and B′, leaving the phy...

Transferring a cavity field entangled state in cavity QED We propose a scheme for transferring an entanglement of zero- and one-photon states from one cavity to another. The scheme, which has 100% success probabil... L Ye,G Guo - 《Journal of Optics B Quantum & Semiclassical Optics》 被引...
Here, we aim at summarizing the state of the art in the development of quantum technologies which have an impact in the field of space applications. Our goal is to outline a complete framework for the design, development, implementation, and exploitation of quantum technology in space....
Because of its being so very fragile, entanglement provides a very sensitive probe to possible new physics in those cases where the SM states are produced in an entangled state which the new physics tends to lessen, modify or brake altogether. In general, by adding extra terms to the SM ...
The evolution of an entangled photon state propagating through a turbulent atmosphere is formulated in terms of a set of coupled first order differential e... FS Roux - 《Physics》 被引量: 6发表: 2010年 Transport of orbital-angular-momentum entanglement through a turbulent atmosphere We demonstrat...
an article published by Washington Post on Aug. 22 last year, with domestic debates in the U.S. over immigration increasingly driven by racialized resentment, anti-immigrant sentiment and entangled with domestic political battles, U.S. policymakers are more inclined to use techniques like force ...
Here we present an on-demand, continuously generated string of indistinguishable photons entangled in a cluster state. We use the heavy-hole (HH) spin26,30,31 as an entangler, utilizing the fact that the HH is left in a stable ground state after photon emission; thus, as we show below,...
