Geometric Invariants of Quantum Metrology
Christopher Wilson, John Drew Wilson, Luke Coffman +2
We establish a previously unexplored conservation law for the Quantum Fisher Information Matrix (QFIM) expressed as follows; when the QFIM is constructed from a set of observables…
Noise constraints on sensitivity scaling in super-Heisenberg quantum metrology
Noah Lordi, John Drew Wilson, Murray J. Holland +1
Quantum-enhanced metrology surpasses classical metrology by improving estimation precision scaling with a resource (e.g., particle number or energy) from to .…
Engineering tunable decoherence-free subspaces with collective atom-cavity interactions
Lyryl H. C. Vaecairn, Jarrod T. Reilly, John Drew Wilson +2
We propose schemes to design and control a time-dependent decoherence-free subspace (DFS) in a dissipative atom-cavity system. These schemes use atoms with three internal energy le…
Universal Gate Set for Optical Lattice Based Atom Interferometry
Catie LeDesma, Kendall Mehling, John Drew Wilson +2
In this paper, we propose a new paradigm for atom interferometry and demonstrate that there exists a universal set of atom optic components for inertial sensing. These components c…
