Determination of the asymptotic limits of adaptive photon counting measurements for coherent-state optical phase estimation
August 10, 2022
Physical realizations of the canonical phase measurement for the optical phase are unknown. Single-shot phase estimation, which aims to determine the phase of an optical field in a single shot, is cri…
General quantum measurements optimally interpolate between measurement paradigms
July 18, 2022
The ability to distinguish between two different quantum states can enable optical communication, cryptography, and networking. However, any overlap between the two states fundamentally limits how wel…
Channel-noise tracking for sub-shot-noise-limited receivers with neural networks
February 24, 2021
(a) A sender (Alice) and receiver (Bob) attempt to communicate across a noisy channel. Bob implements a state discrimination measurement based on photon counting to decode the information sent by Alic…
Optical phase estimation approaching the quantum limit in a single shot.
December 3, 2020
Optical phase estimation is at the center of many metrological tasks where the value of a physical parameter of a system is mapped to the phase of an electromagnetic field, and single-shot measurement…
Four CQuIC Faculty Receive EAGER Awards
September 2, 2020
EArly-concept Grants for Exploratory Research (EAGER) are awarded by the National Science Foundation (NSF) each year to support exploratory work in its early stages on untested, but potentially transf…
Phase tracking for sub-shot-noise-limited receivers
July 6, 2020
Nonconventional receivers for phase-coherent states based on non-Gaussian measurements such as photon counting surpass the sensitivity limits of shot-noise-limited coherent receivers, the quantum nois…
Becerra Chavez publishes Low Power Light article in Nature Partner Journals
April 17, 2020
Light has intrinsic quantum noise, which limits how well we can measure it, especially at low powers, and bounds how much information we can communicate. A team led by F. Elohim Becerra at the Univers…
Becerra’s group publishes article on robust measurements at low powers by counting photons
July 30, 2018
Optical communication uses light to encode and transmit information over long distances, such as in optical fibers with losses, and requires reliable detection schemes to read out information from low…
Becerra’s group publishes article on multiple coherent states in Journal of Optical Society of America B
March 19, 2018
Measurement strategies for multiple coherent states based on single-shot measurements with photon counting can be useful for high bandwidth communications with high spectral efficiency. The quantum-op…
