Photonic Quantum Information and Communication Lab
Machine-translated · View original
The lab studies photonic quantum information and communication, researching quantum computers built on photonic integrated circuits.
AboutAbout the lab
Taking on quantum information and communication with optical circuits.
The lab studies how to build quantum information processing devices and systems using photonic integrated circuits.
Current information processing and communication map signals onto classical, macroscopic quantities such as voltage and frequency, and it has been pointed out that this approach is approaching its limits in information density and speed.
In contrast, there are strong expectations for the practical use of quantum information and communication technologies, which encode information in microscopic quantities such as individual electrons and photons and directly use the principles of quantum mechanics.
The lab works on developing technologies that will be at the core of quantum information and communication in the near future.
Key terms
- Silicon photonics
- A technology for building integrated circuits for light on silicon. It allows circuits that guide light to be packed onto a small chip.
- Photon
- A particle of light. In this lab, information is encoded in photons and processed.
- Quantum simulator
- A device that uses the properties of quantum mechanics to reproduce and investigate quantum phenomena.
