Current information processing and communication technology utilizes macroscopic and classical physical quantities, such as voltage or frequency of electric fields. The classical technology will reach the limit of information density and speed in the near future. The quantum mechanical counterpart, “quantum info-communication technology” , in which information is carried by microscopic and quantum mechanical quantities, is expected to overcome the difficulty.

Our goal is to develop the quantum info-communication devices utilizing quantum interaction between electrons and photons in semiconductor nanostructures, to get further understanding of their physics, and to apply them to practical quantum info-communication technologies. We are particularly working toward the development of future quantum info-communication devices utilizing entangled photon pairs and electron spins in semiconductor nanostructures.

Research topics:

  1. Photon-control devices with semiconductor nanostructures
  2. Quantum info-communication devices utilizing photons and electron spins
  3. Quantum info-communication technology utilizing entangled states of photons and electrons
