We demonstrate a wideband continuous microwave-to-optical conversion scheme based on a warm atomic system. The scheme enables counting microwave pho-tons with 57dB dynamic range, reaching 4K thermal radiation limit, and allows all-optical phase-sensitive detection of weak microwave fields.

We present a room-temperature atomic system used as a microwave-to-optical transducer operating in the single-photon regime. Coherence of the phase-matched conversion and photon-counting detection of microwave blackbody radiation are demonstrated.

Sebasian Borówka, Wiktor Krokosz, Wojciech Wasilewski +2 more

Upconversion of electromagnetic waves to the optical domain gives unique perspectives for novel detection systems. We present a quantum-limited, Rydberg-atom enabled system capable of detecting microwaves from photonic or electronic sources across a broad range of frequencies.

We present a phase-sensitive local oscillator-free detection scheme utilizing the microwave loop scheme using warm Rydberg atoms. We compare its behaviour with the heterodyne detection in the same setup and discuss its limitations.

Continuous wideband microwave-to-optical converter based on room-temperature Rydberg atoms

Abstract The coupling of microwave and optical systems presents an immense challenge due to the natural incompatibility of energies, but potential applications range from optical interconnects for quantum computers to next-generation quantum microwave sensors, detectors and coherent imagers. Several of the engineered platforms that have emerged are constrained by specific conditions, such as cryogenic environments, impulse protocols or narrowband fields. Here we employ Rydberg atoms that allow the wideband coupling of optical and microwave photons at room temperature with the use of a modest set-up. We present continuous-wave conversion of a 13.9 GHz field to a near-infrared optical signal using an ensemble of Rydberg atoms via a free-space six-wave mixing process designed to minimize noise interference from any nearby frequencies. The Rydberg photonic converter exhibits a conversion dynamic range of 57 dB and a wide conversion bandwidth of 16 MHz. Using photon counting, we demonstrate the readout of photons of free-space 300 K thermal background radiation at 1.59 nV cm −1 rad −1/2 s −1/2 (3.98 nV cm −1 Hz −1/2 ) with a sensitivity down to 3.8 K of noise-equivalent temperature, allowing us to observe Hanbury Brown and Twiss interference of microwave photons.Abstract The coupling of microwave and optical systems presents an immense challenge due to the natural incompatibility of energies, but potential applications range from optical interconnects for quantum computers to next-generation quantum microwave sensors, detectors and coherent imagers.
