Photonis single-photon-detection solutions are based on vacuum-tube detector technology. This technology combines high detection efficiency (QE) with an extremely low amount of dark counts (dark noise). After pulsing, the phenomenon in which a detector generates a pulse after it already has detected a photon is minimal, and dead time is non-existent. Photonis’s patented high-end microchannel … Continue reading
Here is a sampling of seven ground-breaking papers regarding photonic sensing published this year from researchers around the world. All this research used one or more of the following ID Quantique products: ID281 Superconducting Nanowire Series Detectors ID230 Infrared Single-Photon Detectors Time Controller Series Devices ID220 Single Photon Counters (precursors to the ID Qube NIR … Continue reading
Entanglement is as wondrous as it is useful. It describes systems where—counter to our everyday intuition of probability—the full state cannot be described as a product of its constituents, and the measurement of one portion of an entangled ensemble will affect the other parts instantaneously, regardless of the separation in space and time. Together with … Continue reading
Webinar Title: How to count – DIY single-photon counting workshop Description of Webinar 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, where Dr. Martin Felle of ID Quantique will explore how … Continue reading
Distributed temperature sensing (DTS) is a great technology for monitoring temperature profiles in structures sensitive to material bulk and/or electrical fields, such as aircraft wings or high-energy particle detectors. Read the results of this latest collaboration between ID Quantique (IDQ) and HEPIA, a photon-counting Raman-based OTDR scheme. In this work, an arrangement of ultra-precise ID281 … Continue reading
In this workshop, Martin Felle from ID Quantique looks at the second- and third-order correlation functions of Quantum Optics, and how to measure them. Whether characterizing purity of your photonic number states for QKD, implementing Hong-Ou-Mandel interferometry for quantum imaging, carrying out photonic Bell state measurements in a quantum relay, correlation function measurements are a … Continue reading
