Photonic quantum memories will play an essential role in synchronizing nodes of quantum networks. Here we present a system that can store polarization and time-bin qubits for up to 12.5 µs over a THz bandwidth.

Cross quadrature correlations are observed from the spectral matrices of two-mode bright states generated in an integrated optical parametric oscillator. We attribute degradation of amplitude difference squeezing with increasing pump intensities to this effect.

High-precision time synchronization is a fundamental requirement for quantum networks. We simulate a global time distribution network by using quantum clock synchronization – sharing entangled photons between satellite-ground station pairs. This provides sub-nanosecond to picosecond level precision over intercontinental scales (better than GPS).

We propose a scheme for generating polarization-entangled photons using the quantum Zeno effect. The observing medium is a series of 4-level atoms coupled to two waveguides. Bunching is suppressed, yielding bipartite and tripartite polarization entanglement.
