Abstract: Ultracold polar molecules are promising candidate qubits for quantum computing and quantum simulations. Their long-lived molecular rotational states form robust qubits, and the long-range dipolar interaction between molecules provides quantum entanglement. We demonstrate dipolar spin-exchange interactions between single CaF molecules trapped in an optical tweezer array.
Soft X-ray Generation Using Mid-Infrared Femtosecond Lasers at High kHz Repetition Rates
When
-
Abstract: High harmonic generation is a unique short wavelength light source with high spatial and temporal coherence, enabling ultrafast pump-probe studies of dynamics in chemical reactions, biological systems, and technologically relevant materials. For soft x-ray generation, this requires ultrafast lasers operating at high pulse energy and high repetition rate in the mid-infrared spectral region, which remain a challenging technology.
Exploring superradiance for enhanced sensors
When
-
I’ll discuss two experimental results that utilize the collective emission of strontium atoms within a cavity, aimed at advancing atomic clock technology. In our first investigation, we employ superradiant pulses from the cavity mode as a fast and directed atomic population readout, mapping out a unique Ramsey spectroscopic lineshape and demonstrating the potential for multiple readouts within a single experimental cycle. In our second investigation, we extend these pulses using an incoherent repumping scheme, achieving steady-state lasing for over a millisecond on the kHz tr

Pushing LIGO’s quantum limits
When
-
Abstract: The Advanced LIGO detectors operate at a regime where quantum uncertainty imposes a fundamental limitation to sensitivity in the form of quantum shot noise and quantum radiation pressure noise. During the last gravitational wave observing run O3, the LIGO and Virgo detectors used quantum states of light known as squeezed states of light in order to reduce high frequency quantum shot noise.
