IQIM Postdoctoral and Graduate Student Seminar

This is a Special IQIM Seminar Tuesday, May 19 beginning at 12 noon.

Abstract: Arrays of neutral atoms have emerged as a powerful and versatile tool for exploring quantum science. In this seminar, I will discuss a pair of efforts at the intersection of quantum information processing, frequency metrology and many-body simulation using strontium atoms which are programmably reconfigured in an optical lattice. The first half of the talk will focus on realizing quantum-enhanced optical atomic clocks using Rydberg-mediated entanglement generation. We demonstrate the preparation of GHZ and spin-squeezed states in an optical clock performing below the standard quantum limit, with advances in multi-qubit entangling gates and autoionization-based mitigation of collective decoherence. In the second part, I will discuss a new bottom-up approach to analog quantum simulation in optical lattices. In contrast to the traditional top-down approach of evaporative cooling to a bulk degenerate gas, we demonstrate how a Fock state of individually tweezer-assembled, laser-cooled atoms can be adiabatically connected to near ground states of a Hubbard-compatible optical lattice. We verify the presence of a significant superfluid fraction near the center of the trap using comparison to quantum Monte Carlo calculations.

Following the talk, lunch will be provided on the lawn outside East Bridge.
