Quantum optics with Rydberg atoms and superconducting resonators is well-established, with attention now towards interfaces with on-chip quantum computing devices [1,2]. We are developing a similar platform using Rydberg excitons – bound states of excitons and holes in a semiconductor. We have measured the largest microwave-optical Kerr coefficient to date [3], and our experiments are able to...
Heat engines convert thermal energy into mechanical work and have been extensively studied in the classical and quantum regimes. In the quantum domain, however, nonclassical forms of energy exist, which are distinct from traditional heat and which can also be harnessed to generate work in cyclic engine protocols.
We introduce the concept of the Pauli engine: a novel quantum many-body...
Rydberg atoms efficiently links photons between the radio-frequency (RF) and optical domains. They provide a medium in which the presence of an RF field imprints on the transmission of a probe laser beam by altering the coherent coupling between atomic quantum states. The immutable quantized energy structure of the atoms underpins quantum-metrological RF field measurements and has driven...
