Prof. Gershoni, Vice Chancellor of Guangdong Technion - Israel Institute of Technology (GTIIT) and Professor of Physics in the Technion together with scientists from his group in the Department of Physics and the Solid-State Institute at the Technion – bring The future of quantum Technology one step closer. In a recent breakthrough together with, doctors Dan Cogan, Zu-En Su, and Oded Kenneth, they have demonstrated a deterministic way to generate chains of entangled and identical photons in clusters.

The group’s current study, published in Nature Photonics, presents a device that uses laser pulses to excite a single semiconductor quantum dot. The device, also called “The Quantum Knitting Machine,” produces periodically 500 million single photons each second, where each photon in this continuous chain is entangled with the previous photon and the next one. The group has shown that every 10 consecutive photons in the chain are entangled.

The work presents the best source of entangled light demonstrated to date in terms of brightness, rate, and entanglement robustness.

“We believe this breakthrough will advance the field of quantum information processing in general and quantum communication in particular. These fields will most likely form the basis of future quantum technologies. Our research motivation stems from basic scientific curiosity; however, we expect that technology will follow science and that soon, we will see wide use of genuine quantum technologies. In the near future, quantum information communication and entanglement distribution could become a feasible reality,” said Prof. Gershoni.
