Real-time time correlated photon counters for photon number resolving detectors

Autor: Yang Lu, Xiao Ai, Mala Sadik, Richard W. Nock

Publikováno v: Optical Sensing and Detection VI.

In this paper, a novel Field Programmable Gate Array (FPGA) based instrument for Time Correlated Photon Counting (TCPC) is reported which takes advantage of the photon number resolving ability of newer single photon detectors technologies, such as si

Experimental characterization of universal one-way quantum computing

Autor: B A Bell, M S Tame, A S Clark, R W Nock, W J Wadsworth, J G Rarity

Publikováno v: New Journal of Physics, Vol 15, Iss 5, p 053030 (2013)

We report the characterization of a universal set of logic gates for one-way quantum computing using a four-photon ‘star’ cluster state generated by fusing photons from two independent photonic crystal fibre sources. We obtain a fidelity for the

We demonstrate a client-server quantum key distribution (QKD) scheme, with large resources such as laser and detectors situated at the server-side, which is accessible via telecom-fibre, to a client requiring only an on-chip polarisation rotator, tha
