Bell Inequalities Tailored to Maximally Entangled States [PDF]
Physical Review Letters, 2017 Bell inequalities have traditionally been used to demonstrate that quantum theory is nonlocal, in the sense that there exist correlations generated from composite quantum states that cannot be explained by means of local hidden variables. With the advent of device-independent quantum information protocols, Bell inequalities have gained an additional ...

Complete and Deterministic discrimination of polarization Bell state assisted by momentum entanglement [PDF]
, 2006 A complete and deterministic Bell state measurement was realized by a simple linear optics experimental scheme which adopts 2-photon polarization-momentum hyperentanglement.

Subradiant Bell States in Distant Atomic Arrays [PDF]
Physical Review Letters, 2019 We study collective `free-space' radiation properties of two distant single-layer arrays of quantum emitters as two-level atoms. We show that this system can support a long-lived Bell superposition state of atomic excitations exhibiting strong subradiance, which corresponds to a non-local excitation of the two arrays.

Experimental Implementation of Projective Measurement in Bell Basis [PDF]
, 2008 A scheme for direct projection of a quantum state on Bell states is described. The method is based on constructing an average Hamiltonian with Bell eigenstates and then, projecting the state on these eigenstates. The projection is performed by adding the

MathematicsStabilizing quantum states in physical qubits quantum computers has been a widely explored topic in the Noisy Intermediate-Scale Quantum era. However, much of this work has focused on simulation rather than practical implementation.

Optical Bell-state analysis in the coincidence basis
, 2002 Many quantum information protocols require a Bell-state measurement of entangled systems. Most optical Bell-state measurements utilize two-photon interference at a beam splitter. By creating polarization-entangled photons with spontaneous parametric down-

Any four orthogonal ququad–ququad maximally entangled states are locally markable
New Journal of Physics, 2023 In quantum state discrimination, the observers are given a quantum system and aim to verify its state from the two or more possible target states. In the local quantum state marking as an extension of quantum state discrimination, there are N composite ...

Quantum Teleportation with a Complete Bell State Measurement
, 2000 We report a quantum teleportation experiment in which nonlinear interactions are used for the Bell state measurements. The experimental results demonstrate the working principle of irreversibly teleporting an unknown arbitrary quantum state from one ...

Analysis for practical realization of number-state manipulation by number-sum Bell measurement with linear optics [PDF]
, 2004 We analyze the linear optical realization of number-sum Bell measurement and number-state manipulation by taking into account the realistic experimental situation, specifically imperfectness of single-photon detector.
