Abstract: Cold atoms provide an ideal platform for many aspects of quantum science, from metrology to simulation to quantum computing and networking.  These applications stem from their status as simple quantum objects, whose degrees of freedom can be controlled and entangled, and whose properties are identical and constant.

Black Marble: Exploring the Earth's Dark Side

Abstract: In this talk I present a method to solve the equations of motion of open quantum many-body systems. It is based on a combination of generalized wave function trajectories and matrix product states. More specifically, we developed an adaptive quantum stochastic propagator, which minimizes the expected entanglement in the many-body quantum state, thus minimizing the computational cost of the matrix product state representation of quantum trajectories.

Lunch will be provided.

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.

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.
