Hands-on at this exhibit

  • Convert an electrical signal from a portable music player to an optical signal.
  • See the weird quantum effects of photon interference using our interactive model.
  • Compete against our ultra-sensitive detectors, can you see single photons?


Light is the ultimate information carrier that could hold the key to making quantum computing a reality.

Incredible quantum light captured on a chip in this video explaining more about the exhibit.

Nothing is faster than light, and photons are ideal candidates for the processing powerhouses needed in much-anticipated quantum computers. Our exhibit will explain the physics of photons, how light can be used to carry information and how we can use photons for quantum information processing.

Light can be generated with high efficiency and sent over huge distances using optical fibres. But we want to harness its properties as an information carrier on a much smaller scale. Our research develops ways to generate, manipulate and detect quantum light on miniature semiconductor chips. While only a few micrometres across, our chips integrate single-photon light sources, nano-photonic circuitry and ultra-sensitive detectors. By trapping and controlling the flow of single photons in tiny optical circuits, we’re producing the building blocks of quantum computers.
