Conditional quantum plasmonic sensing

open access: yesNanophotonics, 2022
Abstract The possibility of using weak optical signals to perform sensing of delicate samples constitutes one of the main goals of quantum photonic sensing. Furthermore, the nanoscale confinement of electromagnetic near fields in photonic platforms through surface plasmon polaritons has motivated the development of highly sensitive ...

On the weekly cycle of atmospheric ammonia over European agricultural hotspots

open access: yesScientific Reports, 2022
The presence of a weekly cycle in the abundance of an atmospheric constituent is a typical fingerprint for the anthropogenic nature of its emission sources. However, while ammonia is mainly emitted as a consequence of human activities, a weekly cycle has

A Molecular Approach to Quantum Sensing [PDF]

open access: yesACS Central Science, 2021
The second quantum revolution hinges on the creation of materials that unite atomic structural precision with electronic and structural tunability. A molecular approach to quantum information science (QIS) promises to enable the bottom-up creation of quantum systems.

Temporal analog of Fabry-Pérot resonator via coherent population trapping

open access: yesnpj Quantum Information, 2021
Ramsey spectroscopy via coherent population trapping (CPT) is essential in precision measurements. The conventional CPT-Ramsey fringes contain numbers of almost identical oscillations and so that it is difficult to identify the central fringe.

Strategies for Positive Partial Transpose (PPT) States in Quantum Metrologies with Noise

open access: yes, 2021
Quantum metrology overcomes standard precision limits and has the potential to play a key role in quantum sensing. Quantum mechanics, through the Heisenberg uncertainty principle, imposes limits on the precision of measurements.

Thermally activated charge fluctuations in GaAs double quantum dots [PDF]

open access: yes, 2014
In this thesis, laterally defined GaAs quantum dots and double quantum dots are investigated by means of real-time charge sensing. A quantum dot charge sensor, adjacent to the investigated double dot system, detects single electron tunneling with ...

Trends in spectrally resolved outgoing longwave radiation from 10 years of satellite measurements

open access: yesnpj Climate and Atmospheric Science, 2021
In recent years, the interest has grown in satellite-derived hyperspectral radiance measurements for assessing the individual impact of climate drivers and their cascade of feedbacks on the outgoing longwave radiation (OLR).

Quantum Plasmonic Sensing Using Squeezed Light [PDF]

open access: yes, 2021
Quantum sensing is an emerging field of quantum optics that seeks to take advantage of quantum correlations available in quantum states of light to enable sensitivities beyond the fundamental classical limits. The sensitivity of measurements and sensing

Quantum-Inspired Terahertz Sensing

open access: yes, 2022
Quantum-inspired terahertz sensing using nonlinear interferometers enables detection of terahertz spectral properties while only measuring visible light, which never interacted with the sample. Applications in spectroscopy and thickness determination are
