A crucial application of this property is that it can be used to test quantum indistinguishability without bringing the relevant particles together, thereby avoiding the effects of mutual interaction. This is in contrast to the existing tests of quantum indistinguishability. Such a scheme, being independent of the nature and strength of mutual interactions of the identical particles involved, has potential applications, including the probing of the transition from quantum indistinguishability to classical distinguishability. date: 2013-04-03 official_url: http://dx.doi.org/10.1103/PhysRevLett.110.140404 vfaculties: VMPS oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_source: WoS-Lite elements_id: 871351 doi: 10.1103/PhysRevLett.110.140404 language_elements: EN lyricists_name: Bose, Sougato lyricists_id: SBOSE77 full_text_status: public publication: Physical Review Letters volume: 110 number: 14 article_number: ARTN 140404 issn: 0031-9007 citation: Bose, S; Home, D; (2013) Duality in Entanglement Enabling a Test of Quantum Indistinguishability Unaffected by Interactions.
