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

Quantum Compressive Sensing: Mathematical Machinery, Quantum Algorithms, and Quantum Circuitry

open access: yes, 2022
Compressive sensing is a sensing protocol that facilitates the reconstruction of large signals from relatively few measurements by exploiting known structures of signals of interest, typically manifested as signal sparsity.

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

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 ...

Quantum ghost imaging for remote sensing

open access: yes, 2022
Paper 111340W, 7 S.We propose an advanced quantum ghost imaging setup for remote sensing applications, which does not rely on preliminary information on the distances of objects and investigate the quantum benefits of this setup for remote sensing ...

Low-Frequency Quantum Sensing

open access: yesPhysical Review Applied, 2022
Exquisite sensitivities are a prominent advantage of quantum sensors. Ramsey sequences allow precise measurement of direct current fields, while Hahn-echo-like sequences measure alternating current fields. However, the latter are restrained for use with high-frequency fields (above approximately $1$ kHz) due to finite coherence times, leaving less ...

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.

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.

Enhancing quantum sensing sensitivity by a quantum memory [PDF]

open access: yesNature Communications, 2016
AbstractIn quantum sensing, precision is typically limited by the maximum time interval over which phase can be accumulated. Memories have been used to enhance this time interval beyond the coherence lifetime and thus gain precision. Here, we demonstrate that by using a quantum memory an increased sensitivity can also be achieved.
