Testing Hardy's nonlocality proof with genuine energy-time entanglement
Physical Review A—Atomic, Molecular, and Optical Physics, 2011•APS
We show two experimental realizations of Hardy's ladder test of quantum nonlocality using
energy-time correlated photons, following the scheme proposed by Cabello [Phys. Rev. Lett.
102, 040401 (2009) PRLTAO 0031-9007 10.1103/PhysRevLett. 102.040401]. Unlike
previous energy-time Bell experiments, these tests require precisely tailored nonmaximally
entangled states. One of them is equivalent to the two-setting and two-outcome Bell test
requiring a minimum detection efficiency. The reported experiments are still affected by the …

We show two experimental realizations of Hardy’s ladder test of quantum nonlocality using energy-time correlated photons, following the scheme proposed by Cabello [Phys. Rev. Lett. 102, 040401 (2009)PRLTAO0031-900710.1103/PhysRevLett.102.040401]. Unlike previous energy-time Bell experiments, these tests require precisely tailored nonmaximally entangled states. One of them is equivalent to the two-setting and two-outcome Bell test requiring a minimum detection efficiency. The reported experiments are still affected by the locality and detection loopholes, but are free of the post-selection loophole of previous energy-time and time-bin Bell tests.
