Atomic Physics Seminar
Reusable Neutral Atom Qubits for Quantum Information Applications
Date: Thursday, September 15th
Time: 2:00 pm
Place: 5310 Chamberlin
Speaker: Michael Gibbons, Georgia Institute of Technology
Abstract: Most neutral atom quantum computing experiments rely on destructive state detection techniques that eject the detected qubits from the trap. These techniques limit the repetition rate of these experiments due to the necessity of reloading a new quantum register for each operation.

We address this problem by developing reusable neutral atom qubits. Individual 87Rb atoms are trapped in an optical lattice and are held for upwards of 300 s. Each atom is prepared in an initial quantum state and the state is subsequently detected with 95% accuracy and with less than a 1% probability of losing it from the trap. The combination of long storage times and lossless state detection could help facilitate the development of faster and more complex quantum operations that will enable future advancements in the field of neutral atom quantum information.
