Quantum Networking and Transduction Group
The Networking & Transduction Group focuses on the interface between stationary quantum computers and mobile quantum information. By researching microwave-to-optical conversion, we are defining the practical limits of how fragile quantum states can be measured and transmitted across diverse networking nodes.
The team is designing and constructing a quantum optical channel to create remote microwave entanglement for the networking of superconducting quantum computers, expected to be operational by the end of 2026.
In this primarily continuous variable approach, the entanglement distribution of optically generated two-mode squeezed states is being used as the quantum resource. At the network nodes, optical states are being down-converted to the microwave domain with doubly parametric, membrane-coupled resonator devices developed at NIST and CU-JILA with the world’s best available transduction performance. Implementation with continuous variables makes possible practical and efficient quantum state preparation, manipulation, and measurement with the potential to support on-demand, high-data rate applications. Alternatively, to combat the debilitating impact of loss on quantum signals, a single photon counting approach is being pursued.
