Two-photon interference between disparate sources for quantum networking
Quantum networks involve entanglement sharing between multiple users. Ideally, any two users would be able to connect regardless of the type of photon source they employ, provided they fulfill the requirements for two-photon interference. From a theoretical perspective, photons coming from different origins can interfere with a perfect visibility, provided they are made indistinguishable in all...
متن کاملSemiconductor quantum light sources
Applying quantum light states to photonic applications allows functionalities that are not possible using ‘ordinary’ classical light. For example, carrying information with single photons provides a means to test the secrecy of optical communications, which could soon be applied to the problem of sharing digital cryptographic keys1,2. Although secure quantum-key-distribution systems based on we...
متن کاملQuantum dot polarized light sources
The design, operation and performance of quantum dot spin-polarized vertical cavity surface emitting lasers (VCSELs) and single-photon sources are described and discussed. The effects of spin-induced gain anisotropy on output polarization and threshold current reduction have been studied along with the high-frequency response in a spin-polarized VCSEL. While the output circular polarization in ...
متن کاملQuantum interference and entanglement induced by multiple scattering of light.
We report on the effects of quantum interference induced by the transmission of an arbitrary number of optical quantum states through a multiple-scattering medium. We identify the role of quantum interference on the photon correlations and the degree of continuous variable entanglement between two output modes. It is shown that quantum interference survives averaging over all ensembles of disor...
متن کاملQuantum Interference between Two Atoms
For the first time, physicists have achieved interference between two separate atoms: when sent towards the opposite sides of a semi-transparent mirror, the two atoms always emerge together. This type of experiment, which was carried out with photons around thirty years ago, had so far been impossible to perform with matter, due to the extreme difficulty of creating and manipulating pairs of in...
