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.
Quantum Key Distribution designed for academia, research institutes and innovation labs
Count more, post-process less and react faster to single-photon experiments, with this all-in-one time-tagging, coincidence correlation and delay/pulse generation system.
Whether for quantum communication, bio-sensing, eye-safe LiDAR, or fluorescence lifetime imaging, the art of counting single photons is no simple task. Join us for the next installation in our DIY workshop series.
Part 2 in the Quantum Relay series. In this workshop, Dr Martin Felle explores some of the schemes for building a Quantum Relay, including the necessary components and sub-systems, and some of the technical challenges you will encounter along the way.
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. He presents a TF entanglement swapping experiment where frequency-resolved Bell-state measurements are used to herald a multitude of frequency-encoded Bell states, using readily-available multimode parametric down conversion sources.

All-in-one time-tagging, coincidence correlation and delay/pulse generation
In this workshop, Dr. Martin Felle from ID Quantique looks at the second- and third-order correlation functions of Quantum Optics, and how to measure them.
The challenge of high-speed single-photon counting: a novel superconducting detector design demonstrating order-of-magnitude improvements, to detect single photons at rates over 200 MHz while maintaining the best-in-class performance of SNSPD systems.
This webinar, presented by Prof. Hugo Zbinden, explores the development of the detector technology that has allowed quantum communication to leave the lab and reach the world of practical QKD.
In this webinar, we explore the technology of superconducting nanowire single-photon detectors, as well as the key scientific applications and emerging technologies they enable, and the benefits therein.

In this webinar, Dr. Enrico Pomarico, HEPIA, Geneva, will describe how high-efficiency SNSPDs can be used to measure temperature profiles of with a cm-scale spatial resolution using standard single-mode optical fibers.
When light is detected at single-photon level, how do you define detector measurement performance? This is even more important when detectors can approach 100% quantum efficiency, which is the case for superconducting nanowire single-photon detection (SNSPD).
In this webinar, we describe a method at the heart of many applications: time-correlated single photon counting (TCSPC) and how it is used in near-infrared (NIR) fluorescence lifetime spectroscopy (FLS).
In partnership with DLR, the German Aerospace Center, this webinar will present a new and compact IC inspection system for benchmarking security ICs.
In this webinar, we cover advanced techniques to characterise multi-photon quantum interference and entanglement in an actual experiment using integrated photonics.

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.
