Quantum Testbeds

We strive to address the critical scientific and engineering obstacles to transition quantum photonic technologies from the confines of well-controlled lab settings to deployable devices and systems with real-world advantages over classical technologies. Increasing the technology readiness level of our quantum photonic devices requires the co-development and integration with ancillary components, including chip-scale lasers, high-speed modulators, ultra-low-loss and tunable components, and low-loss packaging for high throughput, reliability, and ruggedness. Through in-house capabilities in our lab and at UCSB, as well as with several collaborators and their testbeds, we have developed and demonstrated quantum source modules with TRL > 6. Simply, our goal is to get promising quantum photonic technologies out of our lab and into the hands of end-users to advance secure communications and networking, sensing, and computing.

Current projects in the QPL include:

• Entanglement-based quantum key distribution (QKD) with deployed SMF-28 fiber across the UCSB campus (collaboration with Cisco)
• High-dimensional quantum state teleportation and networking (collaboration with ORNL)
• Quantum secure time transfer for clock synchronization (collaboration with memQ)
• Quantum photonic sensing (collaboration with Pintus at Cagliari / UCSB and Caroline Ross at MIT)
