Optimal measurements for quantum spatial superresolution
J. Rehacek, Z. Hradil, D. Koutny +3
We construct optimal measurements, achieving the ultimate precision predicted by quantum theory, for the simultaneous estimation of centroid, separation, and relative intensities o…
Multiparameter Quantum Metrology of Incoherent Point Sources: Towards Realistic Superresolution
J. Rehacek, Z. Hradil, B. Stoklasa +4
We establish the multiparameter quantum Cramér-Rao bound for simultaneously estimating the centroid, the separation, and the relative intensities of two incoherent optical point so…
Simple factorization of unitary transformations
Hubert de Guise, Olivia Di Matteo, Luis L. Sanchez-Soto
We demonstrate a method for general linear optical networks that allows one to factorize any SU() matrix in terms of two SU( blocks coupled by an SU(2) entangling beam spl…
Discrete phase-space structures and Wigner functions for qubits
C. Munoz, A. B. Klimov, L. L. Sanchez-Soto
We further elaborate on a phase-space picture for a system of qubits and explore the structures compatible with the notion of unbiasedness. These consist of bundles of discrete…
Joint measurement of complementary observables in moment tomography
Yong Siah Teo, Christian R. Muller, Hyunseok Jeong +3
Wigner and Husimi quasi-distributions, owing to their functional regularity, give the two archetypal and equivalent representations of all observable-parameters in continuous-varia…
Towards optimal quantum tomography with unbalanced homodyning
Yong Siah Teo, Hyunseok Jeong, Luis L. Sanchez-Soto
Balanced homodyning, heterodyning and unbalanced homodyning are the three well-known sampling techniques used in quantum optics to characterize all possible photonic sources in con…
