Linear optical scheme for error-free entanglement distribution and a quantum repeater
Demetrios Kalamidas
We present a linear optical scheme for error-free distribution of two-photon polarization entangled Bell states over noisy channels. The scheme can be applied to an elementary quan…
Possibly novel demonstration of nonlocality for two maximally entangled particles
Demetrios Kalamidas
We present, at the gedanken level, a possibly novel non-statistical demonstration of nonlocality for two maximally entangled particles. The argument requires only two alternative e…
Single-photon quantum error rejection and correction with linear optics
Demetrios Kalamidas
We present single-photon schemes for quantum error rejection and correction with linear optics. In stark contrast to other known proposals, our schemes do not require multi-photon…
Hardy-type nonlocality proof for two maximally entangled particles
Demetrios Kalamidas
We present a variation on a gedanken experiment of Hardy [Phys. Rev. Lett. 68 (1992) 2981] that allows, for the first time, a Hardy-type nonlocality proof for two maximally entangl…
