Sources, Detectors, Components and Applications

Welcome to the home of the Single Photon Workshop 2015, which will be held at the University of Geneva. SPW2015 is the seventh instalment in a series of workshops on single-photon technologies and applications. Single-photon technologies are vital to applications such as quantum cryptography, quantum information processing, quantum imaging, and quantum metrology. Fields such as astrophysics, nuclear physics, and biology also benefit from developments in single-photon technologies.

SPW 2015 is intended to bring together a broad range of people with interests in single-photon sources, single-photon detectors, photon entanglement, and their incorporation into scientific and industrial tools. Researchers from universities, industry, and government will report on the latest developments in single-photon devices and methods with a view toward improved performance and new application areas. It will be an exciting opportunity for those interested in single-photon technologies to learn about the state of the art and to foster continuing partnerships with others seeking to advance the capabilities of such technologies.

The workshop will cover the following and related topics:

Single-photon detectors:

• SPADs.
• Superconducting detectors.
• Detector arrays.
• Photon-number resolving detectors.

Single-photon sources:

• Single-photon sources; e.g. heralded SPDC, NV centers, quantum dots.
• Entangled photon-pair sources.

Metrology:

• Characterisation of detectors and sources.
• Sensing.
• Weak measurements.

Applications of single photon technologies:

• Quantum communications; e.g. quantum key distribution, teleportation.
• Quantum random number generators.
• Biology/Chemistry; e.g. fluorescence spectroscopy, singlet-oxygen detection
• Telecom; e.g. photon-counting communication, instrumentation.
• Imaging; e.g. LIDAR, astronomy.
