A hybrid method of generating spin-squeezed states for quantum-enhanced atom interferometry
Liam Fuderer, Joseph J Hope, Simon A Haine
We introduce a new spin-squeezing technique that is a hybrid of two well established spin-squeezing techniques, quantum nondemolition measurement (QND) and one-axis twisting (OAT).…
Achieving the fundamental quantum limit of linear waveform estimation
James W. Gardner, Tuvia Gefen, Simon A. Haine +2
Sensing a classical signal using a linear quantum device is a pervasive application of quantum-enhanced measurement. The fundamental precision limits of linear waveform estimation,…
Fundamental Limits of Feedback Cooling Ultracold Atomic Gases
Zain Mehdi, Simon A. Haine, Joseph J. Hope +1
We investigate the fundamental viability of cooling ultracold atomic gases with quantum feedback control. Our study shows that the trade-off between the resolution and destructiven…
Signatures of Quantum Gravity in the Gravitational Self-Interaction of Photons
Zain Mehdi, Joseph J. Hope, Simon A. Haine
We propose relativistic tests of quantum gravity using the gravitational self-interaction of photons in a cavity. We demonstrate that this interaction results in a number of quantu…
Feedback cooling Bose gases to quantum degeneracy
Matthew L. Goh, Zain Mehdi, Richard L. Taylor +5
Degenerate quantum gases are instrumental in advancing many-body quantum physics and underpin emerging precision sensing technologies. All state-of-the-art experiments use evaporat…
Mutual friction and diffusion of two-dimensional quantum vortices
Zain Mehdi, Joseph J. Hope, Stuart S. Szigeti +1
We present a microscopic open quantum systems theory of thermally-damped vortex motion in oblate atomic superfluids that includes previously neglected energy-damping interactions b…
