Redefining Single-Photon Detection Technology

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

The Power of Entanglement

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

Detecting Hot Spots with a Light Touch

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

How to Webinar: Quantum Optics and Correlation Function Measurements

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
