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…
Information gain and measurement disturbance for quantum agents
Arthur O. T. Pang, Noah Lupu-Gladstein, Y. Batuhan Yilmaz +4
The traditional formalism of quantum measurement (hereafter ``TQM'') describes processes where some properties of quantum states are extracted and stored as classical information.…
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…
Experimental Comparison of Bohm-like Theories with Different Ontologies
Arthur O. T. Pang, Hugo Ferretti, Noah Lupu-Gladstein +5
The de Broglie-Bohm theory is a hidden variable interpretation of quantum mechanics which involves particles moving through space with definite trajectories. This theory singles ou…
