Quantum Communication & Cryptography

bet365ÊÖ»ú°æ are at the forefront of enabling future quantum communications infrastructure. Our technologies provide solutions to a wide range of challenges in this rapidly evolving market and are critical to the development of a future quantum internet. These include:

  • Robust, high quality, scalable fabrication of integrated photonic components
  • World-leading cameras for detection of single-photon and quantum entanglement
  • Cryo-free and flow cryostats for R&D on novel quantum communication and memory

Today’s datacom infrastructure cloud can become vulnerable to attack by future quantum computers. Furthermore, anything communicated today may be stored and accessed in the future by a hacker armed with a quantum computer. Quantum communications encompasses new methods of securing our digital information. Miniaturisation of components, systems integration and reduction in power consumption plays a critical role when designing photonic architectures impacting in quantum technologies.

Quantum communications relies on enabling components such as quantum random number generators, quantum repeaters etc. To ensure true randomness, seed numbers and algorithms can be replaced by a quantum physical process. InP lasers and InGaAs avalanche photodiodes are used to generate and detect random photon streams. Telecoms and financial services organisations have established programs for disaster recovery and secure communications in place today using quantum key distribution.

Detection of Single Photons and Quantum Entanglement

Our iXon Ultra EMCCD imaging cameras are used to superb effect in systems where spatially correlated photons, incident on an imaging array, need to be detected with superb levels of discrimination and confidence, ultimately yielding accelerated measurement throughout.

Cryostats with optical access for low temperature measurements

Sources of single photons on demand form critical components to enable quantum communication protocols like QKD, PQC as well as to enable coherent sources of photons for quantum repeaters, for example. To maximise the expected secure key and the communication distance for quantum key distribution, and to enable robust high throughput detection of incoming photons, new device and protocols need to be developed which require integration of the detector devices on low-temperature optical cryostats. bet365ÊÖ»ú°æ provide flexible cryogenic solutions with several optical access, measurement and cooling options.
