An international research group of scientists and engineers led by the University of Bristol, UK, has made an important advance towards a quantum computer by shrinking down key components and integrating them onto a silicon microchip.
Scientists and engineers from an international collaboration led by Dr Mark Thompson from the University of Bristol have, for the first time, generated and manipulated single particles of light (photons) on a silicon chip – a major step forward in the race to build a quantum computer.
Quantum computers and quantum technologies in general are widely anticipated as the next major technology advancement, and are poised to replace conventional information and computing devices in applications ranging from ultra-secure communications and high-precision sensing to immensely powerful computers. Quantum computers themselves will likely lead to breakthroughs in the design of new materials and in the discovery of new medical drugs.
Whilst still in their infancy, quantum technologies are making rapid process, and a revolutionary new approach pioneered by the University of Bristol is exploiting state-of-the-art engineering processes and principles to make leaps and bounds in a field previously dominated by scientists.
Featuring on the front cover of Nature Photonics, this latest advancement is one of the important pieces in the jigsaw needed in order to realise a quantum computer. While previous attempts have required external light sources to generate the photons, this new chip integrates components that can generate photons inside the chip.
“We were surprised by how well the integrated sources performed together,” admits Joshua Silverstone, lead author of the paper. “They produced high-quality identical photons in a reproducible way, confirming that we could one day manufacture a silicon chip with hundreds of similar sources on it, all working together. This could eventually lead to an optical quantum computer capable of performing enormously complex calculations.”
Group leader Mark Thompson explained: “Single-photon detectors, sources and circuits have all been developed separately in silicon but putting them all together and integrating them on a chip is a huge challenge. Our device is the most functionally complex photonic quantum circuit to date, and was fabricated by Toshiba using exactly the same manufacturing techniques used to make conventional electronic devices. We can generate and manipulate quantum entanglement all within a single mm-sized micro-chip.”
