✦ Synopsis

We report on theoretical and experimental demonstration of high-efficiency coupling of two-photon entangled states produced in the nonlinear process of spontaneous parametric down conversion into a single-mode fiber. We determine constraints for the optimal coupling parameters. This result is crucial for practical implementation of quantum key distribution protocols with entangled states.

When two photons are coded into entangled polarization states, one of the eigenstates of the direct product of the fiber transfer function matrix is found to be independent of the transmission fiber birefringence. The eigenstate is the entangled singlet state < , one of the Bell states. The entangle

## Abstract We create pairs of non‐degenerate time‐bin entangled photons at telecom wavelengths with ultra‐short pump pulses. Entanglement is shown by performing Bell kind tests of the Franson type with visibilities of up to 91 time‐bin entanglement can easily be protected from decoherence as encou

We have obtained quantum states of light from the emission of an isolated InAs quantum dot. Single photon emission is observed via correlation experiments. Moreover, cross-correlation experiments reveal the sequential de-excitation of the quantum dot, yielding a radiative cascade that produces two s
