Estimation of a parameter encoded in the modal structure of a light beam: a quantum theory
Manuel Gessner, Nicolas Treps, Claude Fabre
Quantum light is described not only by a quantum state but also by the shape of the electromagnetic modes on which the state is defined. Optical precision measurements often estima…
Frequency multiplexed entanglement for continuous-variable quantum key distribution
Olena Kovalenko, Young-Sik Ra, Yin Cai +4
Quantum key distribution with continuous variables already uses advantageous high-speed single-mode homodyne detection with low electronic noise at room temperature. Together with…
Spatiotemporal entanglement in a noncollinear optical parametric amplifier
L. La Volpe, S. De, M. I. Kolobov +4
We theoretically investigate the generation of two entangled beams of light in the process of single-pass type-I noncollinear frequency degenerate parametric downconversion with an…
Spatial optical mode demultiplexing as a practical tool for optimal transverse distance estimation
Pauline Boucher, Claude Fabre, Guillaume Labroille +1
We present the experimental implementation of simultaneous spatial multimode demultiplexing as a distance measurement tool. We first show a simple and intuitive derivation of the F…
Superresolution Limits from Measurement Crosstalk
Manuel Gessner, Claude Fabre, Nicolas Treps
Superresolution techniques based on intensity measurements after a spatial mode decomposition can overcome the precision of diffraction-limited direct imaging. However, realistic m…
Quantum Enhanced Measurement of an Optical Frequency Comb
Y. Cai, J. Roslund, V. Thiel +2
Measuring the spectral properties of an optical frequency comb is among the most fundamental tasks of precision metrology. In contrast to general single-parameter measurement schem…
