The linear optical response of the quantum vacuum
Margaret Hawton, Luis L. Sanchez-Soto, Gerd Leuchs
We show that the interpretation of as vacuum polarization is consistent with quantum electrodynamics. A free electromagnetic field polarizes…
Quantum field theory and classical optics: determining the fine structure constant
Gerd Leuchs, Margaret Hawton, Luis L. Sanchez-Soto
The properties of the vacuum are described by quantum physics including the response to external fields such as electromagnetic radiation. Of the two parameters that govern the det…
Quantum metrology at the limit with extremal Majorana constellations
F. Bouchard, P. de la Hoz, G. Bjork +8
Quantum metrology allows for a tremendous boost in the accuracy of measurement of diverse physical parameters. The estimation of a rotation constitutes a remarkable example of this…
Extracting the physical sector of quantum states
Dmitri Mogilevtsev, Yong-Siah Teo, Jaroslav Rehacek +6
The physical nature of any quantum source guarantees the existence of an effective Hilbert space of finite dimension, the physical sector, in which its state is completely characte…
Dispelling Rayleigh's Curse
J. Rehacek, M. Paur, B. Stoklasa +3
We devise a systematic method to determine the Fisher information required for resolving two incoherent point sources with a diffraction-limited linear imaging device. The resultin…
Achieving quantum-limited optical resolution
Martin Paur, Bohumil Stoklasa, Zdenek Hradil +2
We establish a simple method to assess the quantum Fisher information required for resolving two incoherent point sources with an imaging system. The resulting Cramér-Rao bound sho…
