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.

We propose a device-independent prepare-and-measure quantum key distribution (DIPQKD) that the transmitter prepares and sends the qubits to the receiver who de-codes by measuring the qubits. Through characterizing the used channel and ruling out any classical strategies of mimicry, one can identify the security of DIPQKD against collective attacks.

We couple InAs quantum dots embedded in a pinin diode to circular bragg gratings, i.e. bullseye cavities. We observe a large Purcell enhancement by a factor of about 15, and an 80% dip in the cavity reflectivity at the quantum dot wavelength. Thus, these devices are promising as single photon sources and repeater nodes in a quantum network.
