Hybrid Quantum Technology Using Solid-State Spin Centers
Abstract
We propose to acquire a dilution refrigerator in order to improve our capability to study cavity quantum-electrodynamics (cavity QED), quantum optics, and light-matter interactions using solid-state quantum spin centers integrated into a hybrid systems architecture. The millikelvin temperatures in a dilution refrigerator will expand the types of materials/centers we are able to research and enable sophisticated experiments that combine solid-state spin qubits with both microwave and optical photons. These experiments are motivated by a desire to build quantum networks, quantum sensors, and quantum computers. Sensitive quantum technologies require cryogenic temperatures to avoid thermal noise. We currently study solid-state quantum spin centers at temperatures of 1.7 K using a helium flow cryostat (Attodry 2100), or at 4 K using Montana Instruments cryostats. This works well for optical characterization but is not suitable for hybrid systems research that combines photonics with other quantum platforms that require colder temperatures. Furthermore, the limited sample space in our current cryostats prohibits useful, spatially large components such as cryogenic microwave electronics. These issues: temperature, materials constraints, and sample space, can all be solved with a dilution refrigerator. The proposed experiments will involve many researchers over the next decade and will greatly contribute to ongoing or pending sponsored DoD projects.(This abstract is approved for public release.)
