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.

We take advantage of disperion engineering in thin-film lithium niobate to generate frequency-separable photon pairs at telecommunication wavelengths. A detailed simulation of phase matching conditions is performed and verified using sum-frequency generation to reveal the desired spectral separability.

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.

The goal of this work is to develop Sb-based nBn infrared detectors operating at 2 µm with Quantum Efficiency (QE) exceeding 99%. These detectors have the potential to significantly increase the sensitivity of future generations of the Laser Interferometer Gravitational-Wave Observatory (LIGO) by exploiting quantum entanglement for sub-Poisson limited laser interferometry.
