"Neutral Atom Quantum Computing and Rydberg blockade"
Cold neutral atoms are promising candidates for quantum information processing as they have long coherence time, excellent scalability, and controllable long-range Rydberg interaction providing means of quantum logic gates. Rydberg interactions can also be used to entangle atoms, such as a superatom, containing non-localized excitation that is shared among its constituents. These superatoms, or ensemble qubits, are alternative building blocks to realize quantum computer and atom-light interface due to its enhanced atom-light coupling and robustness against atom loss. In this talk, I will present experimental results from our group preparing and verifying ensemble qubits, interaction between two ensembles, and non-destructive state-dependent fluorescence detection of atomic qubits. I will discuss the underlying physics that has been limiting us, and present means to overcome the limitations. In the latter part of my talk, I will report recent development on novel 2d trapping technique and higher fidelity entanglement of single-atom qubits.
Minho is a postdoc on Atomic Qubit Array project in Mark Saffman's research group, working toward realization of neutral atom quantum computers. He received his Ph.D in Physics at the University of Wisconsin-Madison, where he explored interesting dynamics of Rydberg atoms in the context of quantum information and computation.
