Quantum key distribution with integrated optics

2014 19th Asia and South Pacific Design Automation Conference (ASP-DAC), 2014
We report on a quantum key distribution (QKD) experiment where a client with an on-chip polarisation rotator can access a server through a telecom-fibre link. Large resources such as photon source and detectors are situated at server-side. We employ a reference frame independent QKD protocol for polarisation qubits and show that it overcomes ...

Planar integrated optics for quantum technologies

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
Optical quantum Information Processing makes use of the quantum mechanical properties of single photons to achieve useful information processing functions. This talk will present work carried out at the University of Southampton on the fabrication of optical waveguide device to realize essential functions for all optical quantum information handling ...

Integrated-Optics Quantum Relay: Preliminary Experiments

2006 European Conference on Optical Communications, 2006
Here we investigate the possibility to increase the maximal achievable distance of a quantum cryptography link using an integrated-optics quantum relay based on the teleportation scheme.

Large-scale integrated quantum optics

Science, 2018
Quantum Optics The ability to pattern optical circuits on-chip, along with coupling in single and entangled photon sources, provides the basis for an integrated quantum optics platform. Wang et al. demonstrate how they can expand on that platform to fabricate very large quantum optical circuitry. They integrated more than 550 quantum optical components

Colloidal Quantum Dots Based Integrated Fiber-optic Detector

Optical Fiber Communication Conference, 2017
We report an integrated fiber-optic detector by dip coating PbS colloidal quantum dots onto a pretreated specialty fiber. We measured the readout current at 1550nm as a function of the optical power, the bias voltage and the distance between the contact electrodes.

Integrated Devices for On-Chip Quantum Optics

2017
This thesis describes the fabrication and characterization of on-chip dome-shaped, Fabry-Perot microcavities for quantum-optics applications. Arrays of cavities were fabricated via a guided delamination buckling self-assembly process within SiO2/Ta2O5 multilayers.
