Picocavity QED: A New Materials Platform for Room-Temperature Control of Quantum Coherence
Abstract
The goal of this project is quantum coherent control of electronic transitions and of vibrational quanta in single molecules at room temperature, through strong quantum-mechanical coupling to the optical field in engineered optical pico-cavities, We will design, synthesize, and assemble integrated single-molecule / pico-cavity systems with atomic precision. We will thereby develop scalable platforms for strong coupling of electronic and vibrational transitions in individual engineered molecules to both classical and quantized electromagnetic fields. Through this project, we aim to demonstrate that optimal quantum control can be used to perform quantuminformation tasks at room temperature in strongly coupled single-molecule /pico-cavity systems. Key research outcomes will be (i) the demonstration of single molecule electronic and vibration strong coupling to pico-cavities at room temperature; (ii) the development of scalable pico-cavity platforms with singlemolecule placement and engineered radiation properties; (iii) the identification and minimization of coupling to dissipative electronic and vibrational bath modes; and (iv) ultrafast optimal quantum-coherent control of the strongly coupled systems. Building on the first near-term goal of the proof-of-concept measurement of Rabi oscillations in pico-cavity single molecule strong coupling (year 2), we will through this project refine quantum protocols towards the demonstration of molecular qubit operation with quantum electromagnetic fields (year 3-4). This research will enable the development of new, room-temperature, solid-state quantum-information platforms across the visible to infrared spectral range. It will also demonstrate a new paradigm for quantum information, in which dissipation is not avoided but is exploited, in concert with rapid driving forces, to drive systems into desired output states. In this way, it will provide benchmarks and fundamental limits for quantum information processing in highly dissipative environments broadly relevant to solid-state quantum-information platforms at all temperatures.
