Real-time shot-noise-limited differential photodetection for atomic quantum control
F. Martin Ciurana, G. Colangelo, Robert J. Sewell +1
We demonstrate high-efficiency, shot-noise-limited differential photodetection with real-time signal conditioning, suitable for feedback-based quantum control of atomic systems. Th…

Ultrasensitive Atomic Spin Measurements with a Nonlinear Interferometer
R. J. Sewell, M. Napolitano, N. Behbood +3
We study nonlinear interferometry applied to a measurement of atomic spin and demonstrate a sensitivity that cannot be achieved by any linear-optical measurement with the same expe…
