Abstract:
Neutral atom-based qubits are highly scalable and controllable. With optical excitation of high-lying, strongly interacting Rydberg states, one can achieve on-demand, laser-controlled interactions for quantum logic operations. We present studies of entangling operations within a two-atom system employing individually-trapped ultra-cold cesium atoms that interact via direct laser coupling to a Rydberg level [1], where the Rydberg-dressed many-body Hamiltonian permits pairwise and beyond-pairwise interaction regimes. We also present a detailed study of a controlled-phase (CPHASE) gate that is insensitive to the detrimental effects of atomic motion and spurious light shifts, and that should enable high-quality entangling operation between atom pairs or within larger ensembles. Towards this end, we also present work towards using digital holography to generate reconfigurable trap arrays.

Biography:
Michael (Mike) Martin received a BS in physics from Harvey Mudd College in 2006, and a PhD in physics from JILA/University of Colorado-Boulder in May 2013. At JILA, he worked in the group of Jun Ye to develop next-generation optical frequency standards, including ultrastable laser systems with <50 mHz linewidth and 1 part in 1016 fractional frequency stability. After completing his PhD, he pursued postdoctoral studies at the California Institute of Technology as an Institute for Quantum Information and Matter Postdoctoral Fellow, working to combine nano-photonic devices with ultracold atomic systems. He joined Sandia National Laboratories (SNL) as a Truman postdoctoral fellow to develop strongly-interacting systems of Rydberg atoms. He is currently a Senior Member of the Technical Staff at SNL.
