Photonic Detector Could Help Build Quantum Computers


Bristol team develop silicon-based photonic detector that can measure quantum behaviour within an integrated chip architecture

Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information.

Scientific effort worldwide is focused on attempting to use silicon photonics to realise quantum technologies, such as super-secure communications, quantum super computers and new ways build increased sensitivity sensors. Silicon photonic chips process information made of light using an area millions of times smaller than if you were to try make the equivalent device using individual lenses, mirrors and other optics.

Now, researchers at the University of Bristol have made a breakthrough for silicon quantum photonics "” they have developed new type of on-chip detector capable of measuring quantum mechanical behaviour within the integrated chip architecture.
