Piezoelectric Control of Quantum States in Solid-State Defects (PIQS)
Abstract
Electromechanically active materials offer a remarkable opportunity to manipulate and enhance the quantum properties of solid-state defects by directly modifying their quantum states. But for these materials to be optimally suited for such applications, it is essential to integrate thin-film electromechanical actuators with spin-host materials that possess exceptional optical and spin properties. The interfaces between these materials must also be rigid and efficiently transfer strain. Furthermore, electromechanical actuators need to demonstrate robust electromechanical effects at cryogenic temperatures, where solid-state defects manifest their most favorable characteristics. Meeting these criteria continues to pose a significant challenge. The Piezoelectric Control of Quantum States in Solid-State Defects (PIQS) team will create next-generation, multi-functional hybrid devices composed of optically active solid-state spin qubits embedded in materials with superior coherence properties that are atomically interfaced to cutting-edge thin-film electromechanical actuators. Mechanically robust interfaces with atomic precision will deliver strain at low voltage levels to defects in nanoscale form factors. High strain application at low temperatures and voltages will enable previously unattainable direct control of the quantum states of optically active spin defects. PIQS will also combine electromechanical actuation with nanophotonics and nanomechanics to achieve transduction between spins, photons, and phonons in the single particle regime.
