Resolving the phase space
Zdenek Hradil, Jaroslav Rehacek
We show that the effective resolution of quantum inference is determined by a sampling Gram operator that defines the experimentally accessible degrees of freedom and the reconstru…
Fundamental and operational limitations of Fisher-information-based quantum metrology
ZdenÄk Hradil, Jaroslav ÅeháÄek
Quantum-enhanced sensing is commonly benchmarked using the quantum Fisher information (QFI), often interpreted as a direct indicator of achievable precision. However, such an inter…
Sampling the spatial coherence of light
M. Vitek, M. Peterek, D. Koutny +6
We introduce a novel application of the Hartmann sensor, traditionally designed for wavefront sensing, to measure the coherence properties of optical signals. By drawing an analogy…
Robust quantum metrology with random Majorana constellations
A. Z. Goldberg, J. R. Hervas, Ãngel S Sanz +8
Even the most classical states are still governed by quantum theory. A number of physical systems can be described by their Majorana constellations of points on the surface of a sp…
