Press Release
Physical Sciences Inc. (PSI) has been awarded a research program from the U.S. Air Force to develop an on-chip Phase Stable Interferometric Time-bin Entangled (PSITE) transceiver
Quantum networking using quantum entanglement is a potentially revolutionary technology with both anticipated application, such as blind quantum computing and secure communications, as well as a host of yet-to-be-discovered uses. To discover such game-changing applications and to reveal the true potential of quantum entanglement, scientist and engineers need standardized and reliable hardware to transmit and receive entangled quantum states of light. While demonstrating standardized devices is of the upmost importance, new technology should improve upon existing demonstrations. One of the largest challenges revealed for single-photon-based networking is successfully transmitting complex entangled states.
To address this challenge, PSI and its university team will combine three key innovations. First, to use time-bin encoding to greatly increase the dimensionality of entangled states while simultaneously reducing the impact of losses. Second, to leverage commercially available photonic integrated circuit platform that can provide nearly all of the needed functionality directly on a chip. Third, to design the devices to be phase-stable using active feedback to make the resulting chips scalable to higher dimensionality entangled states. This approach will result in a Phase Stable Interferometric Time-bin Entangled (PSITE) transceiver that will facilitate exploring quantum-entanglement applications.
PSI’s PSITE transceivers developed under this program will become a standardized component for time-bin entanglement generation. These highly mass-producible, robust devices will not only enable anticipated applications such as blind quantum computing, quantum networking, and secure communications, but these devices will enable engineers and researchers to explore new applications that harness the unique features of quantum entanglement.
