Compressing Quantum Fisher Information
Rui Jie Tang, Jeremy Guenza Marcus, Noah Lupu-Gladstein +5
We show that the quantum Fisher information about any phase parameter encoded in a family of pure quantum states can be faithfully compressed into a single qubit, accompanied by a…
Spin coherence scale: operator-ordering sensitivity beyond the Heisenberg-Weyl group
Aaron Z. Goldberg, Andre J. Rodrigues, Y. Batuhan Yilmaz +2
We introduce the spin coherence scale as a measure of quantum coherence for spin systems, generalizing the quadrature coherence scale (QCS) previously defined for quadrature observ…
Generating a 4-photon Tetrahedron State: Towards Simultaneous Super-sensitivity to Non-commuting Rotations
Hugo Ferretti, Y. Batuhan Yilmaz, Kent Bonsma-Fisher +5
It is often thought that the super-sensitivity of a quantum state to an observable comes at the cost of a decreased sensitivity to other non-commuting observables. For example, a s…
Negative quasiprobabilities enhance phase estimation in quantum-optics experiment
Noah B. Lupu-Gladstein, Batuhan Y. Yilmaz, David R. M. Arvidsson-Shukur +4
Operator noncommutation, a hallmark of quantum theory, limits measurement precision, according to uncertainty principles. Wielded correctly, though, noncommutation can boost precis…
