Watch Dr Michal Parniak from The Centre for Quantum Optical Technologies QOT, University of Warsaw talk about the counting of microwave photons through upconversion based on room-temperature Rydberg atoms.
In this webinar, we introduced very briefly, QKD and present the state of the art of the technology. In the second part of the webinar, we also presented new, extremely fast SNSPDs, especially designed for QKD and demonstrate extremely high secret key rates over short distances.
In this short video Félix Bussières, VP Research and Technology at ID Quantique, discusses two innovative approaches to photon-number resolution and ultrafast detection using SNSPDs. Topics include characterization of these devices’ PNR performance and recovery times, IDQ’s related product offerings, and applications to improved heralded single-photon sources and high key-rate QKD.

In this webinar, Eleni Diamanti, CNRS Research Director at the LIP6 laboratory at Paris-Sorbonne, and Vice Director of the Paris Centre for Quantum Computing, explores some of the advantages in security and computational efficiency from the use of quantum resources, with useful applications in the context of quantum networks, including quantum cryptographic tasks and quantum communication complexity.
In this use case, we explore the work of the Institut de Physique de Nice, EPFL, and the XLIM Institute as they use high-performance photonic entanglement sources, for applications from scalable quantum computing to material characterization in manufacturing next-gen photonic devices.

In this webinar, Sofiane Merkouche, PhD Candidate at the Oregon Center for Optical, Molecular and Quantum Science (University of Oregon) shows one way of harnessing the high-dimensional nature of TF entanglement.

8 Channel Time to Digital Converter
Antibunching measurements with InGaAs SPAD detectors are faced with the problems of high background count rate, afterpulsing, and the requirement to gate the SPADs. This application note describes how anti-bunching measurements can be performed by using pulsed excitation and gated detection. Possible problems of the principle are discussed and hints for the buildup of suitable experiments are given.
We describe picosecond time-resolved optical signal recording in the spectral range from 900 nm to 1700 nm. The system consists of an ID Quantique ID220 InGaAs SPAD, a bh SPC-150 TCSPC device, and a B&H BDS-SM 1064 nm ps diode laser.
The purpose of this application note is to compare secret key generation rates of our MDI-QKD system when being operated with standard ID200, and newer and more performant ID210 InGaAs-avalanche photodiode-based SPDs. When using the ID210 detectors, we find a fivefold increase in key rate for a distance of 60 km between users, and the possibility to distribute secret keys over longer distances.
