Techniques in frequency stabilization of lasers to fixed-spacer optical cavities have advanced to the point where the ultimate frequency stabilities are limited by thermal noise in the cavity materials for standard cavity configurations at room tempe

Magnetic-free optomechanically induced nonreciprocity may stimulate a wide range of practical applications in quantum technologies. However, how to suppress the thermal noise flow from the mechanical reservoir is still a difficulty encountered in ach

10$^{-15}$-level laser stabilization down to fiber thermal noise limit using balanced photodetection
We demonstrate a self-homodyne detection method to stabilize a continuous-wave 1550-nm laser to a 1-km optical fiber delay line, achieving a frequency instability of 6.3x10-15 at a 16-ms averaging time. This result, limited by fiber thermal noise, is

Spin qubits in gate-defined quantum dots (QDs) are emerging as a leading technology due to their scalability and long coherence times. However, maintaining these qubits at ultra-low temperatures typically requires complex cryogenic systems. This pape

Overcoming the Thermal-Noise Limit of Microwave Measurements by Pre-cooling with an Active Cold Load
Autor:
Chen, Kuan-Cheng, Oxborrow, Mark
We introduce a method, which we here name ``active pre-cooling'' (APC), for removing, just prior to performing a measurement, a large fraction of the deleterious thermal photons that would otherwise occupy the electromagnetic modes of a microwave cav

The recent paper by Li et al. on electron quasi-thermal noise in the outer heliosphere is flawed. It assumes the plasma drift speed to be much smaller than the electron thermal speed, even though both quantities are of the same order of magnitude in
