Coherence of Rabi oscillations with spin exchange

Autor: C. Kiehl, D. Wagner, T.-W. Hsu, S. Knappe, C. A. Regal, T. Thiele

Publikováno v: Physical Review Research, Vol 5, Iss 1, p L012002 (2023)

Rabi measurements in atomic vapor cells are of current interest in a range of microwave imaging and sensing experiments, but are increasingly in a parameter space outside of theoretical studies of coherence defined by spin-exchange collisions. Here,

Single-Atom Trapping in a Metasurface-Lens Optical Tweezer

Autor: T.-W. Hsu, W. Zhu, T. Thiele, M. O. Brown, S. B. Papp, A. Agrawal, C. A. Regal

Publikováno v: PRX Quantum, Vol 3, Iss 3, p 030316 (2022)

Optical metasurfaces of subwavelength pillars have provided new capabilities for the versatile definition of the amplitude, phase, and polarization of light. In this work, we demonstrate that an efficient dielectric metasurface lens can be used to tr

Autor: B. M. Brubaker, J. M. Kindem, M. D. Urmey, S. Mittal, R. D. Delaney, P. S. Burns, M. R. Vissers, K. W. Lehnert, C. A. Regal

Publikováno v: Physical Review X, Vol 12, Iss 2, p 021062 (2022)

The demonstration of a quantum link between microwave and optical frequencies would be an important step toward the realization of a quantum network of superconducting processors. A major impediment to quantum electro-optic transduction in all platfo

Improving Broadband Displacement Detection with Quantum Correlations

Autor: N. S. Kampel, R. W. Peterson, R. Fischer, P.-L. Yu, K. Cicak, R. W. Simmonds, K. W. Lehnert, C. A. Regal

Publikováno v: Physical Review X, Vol 7, Iss 2, p 021008 (2017)

Interferometers enable ultrasensitive measurement in a wide array of applications from gravitational wave searches to force microscopes. The role of quantum mechanics in the metrological limits of interferometers has a rich history, and a large numbe

Strong Optomechanical Squeezing of Light

Autor: T. P. Purdy, P.-L. Yu, R. W. Peterson, N. S. Kampel, C. A. Regal

Publikováno v: Physical Review X, Vol 3, Iss 3, p 031012 (2013)

We create squeezed light by exploiting the quantum nature of the mechanical interaction between laser light and a membrane mechanical resonator embedded in an optical cavity. The radiation-pressure shot noise (fluctuating optical force from quantum l

Cooling a Single Atom in an Optical Tweezer to Its Quantum Ground State

Autor: A. M. Kaufman, B. J. Lester, C. A. Regal

Publikováno v: Physical Review X, Vol 2, Iss 4, p 041014 (2012)

We report cooling of a single neutral atom to its three-dimensional vibrational ground state in an optical tweezer. After employing Raman sideband cooling for tens of milliseconds, we measure via sideband spectroscopy a three-dimensional ground-state
