Characterising a Single-Photon Detector for ALPS II

open access: yesJournal of Low Temperature Physics, 2022
AbstractTransition Edge Sensors (TESs) have found widespread application in fundamental studies due to their low background rate, high efficiency, and excellent energy resolution. This makes them suitable candidates for ALPS II, which investigates the existence of new particles (axions and axion-like-particles) which couple very weakly to photons. ALPS

Single-Shot Quantum Nondemolition Detection of Individual Itinerant Microwave Photons

open access: yesPhysical Review X, 2018
Single-photon detection is an essential component in many experiments in quantum optics, but it remains challenging in the microwave domain. We realize a quantum nondemolition detector for propagating microwave photons and characterize its performance ...

Collapse dynamics and Hilbert-space stochastic processes

open access: yesScientific Reports, 2021
Spontaneous collapse models of state vector reduction represent a possible solution to the quantum measurement problem. In the present paper we focus our attention on the Ghirardi–Rimini–Weber (GRW) theory and the corresponding continuous localisation ...

Niobium Superconducting Nanowire Single-Photon Detectors [PDF]

open access: yesIEEE Transactions on Applied Superconductivity, 2009
We investigate the performance of superconducting nanowire photon detectors fabricated from ultra-thin Nb. A direct comparison is made between these detectors and similar nanowire detectors fabricated from NbN. We find that Nb detectors are significantly more susceptible than NbN to thermal instability (latching) at high bias.

Advantages of gated silicon single-photon detectors [PDF]

open access: yesApplied Optics, 2012
We present a gated silicon single photon detector based on a commercially available avalanche photodiode. Our detector achieves a photon detection efficiency of 45\pm5% at 808 nm with 2x 10^-6 dark count per ns at -30V of excess bias and -30°C. We compare gated and free-running detectors and show that this mode of operation has significant advantages ...
