Theoretical studies on quantum imaging with time-integrated single-photon detection under realistic experimental conditions
Byeong-Yoon Go, Changhyoup Lee, Kwang-Geol Lee
We study a quantum-enhanced differential measurement scheme that uses quantum probes and single-photon detectors to measure a minute defect in the absorption parameter of an analyt…
Multiplexed sensing of magnetic field and temperature in real time using a nitrogen vacancy spin ensemble in diamond
Jeong Hyun Shim, Seong-Joo Lee, Santosh Ghimire +7
Nitrogen-Vacancy (NV) spin in diamond is a versatile quantum sensor, being able to measure physical quantities such as magnetic field, electric field, temperature, and pressure. In…
Quantum Plasmonic Sensors
Changhyoup Lee, Benjamin Lawrie, Raphael Pooser +3
The extraordinary sensitivity of plasmonic sensors is well known in the optics and photonics community. These sensors exploit simultaneously the enhancement and the localization of…
Experimental quantum polarimetry using heralded single photons
Seung-Jin Yoon, Joong-Sung Lee, Carsten Rockstuhl +2
We perform experimental quantum polarimetry using a heralded single photon to analyze the optical activity of linearly polarized light traversing a chiral medium. Three kinds of es…
Quantum plasmonic sensing using single photons
Joong-Sung Lee, Seung-Jin Yoon, Hyungju Rah +5
Reducing the noise below the shot-noise limit in sensing devices is one of the key promises of quantum technologies. Here, we study quantum plasmonic sensing based on an attenuated…
Quantum noise reduction in intensity-sensitive surface plasmon resonance sensors
Joong-Sung Lee, Trung Huynh, Su-Yong Lee +5
We investigate the use of twin-mode quantum states of light with symmetric statistical features in their photon number for improving intensity-sensitive surface plasmon resonance (…
A planar dielectric antenna for directional single-photon emission and near-unity collection efficiency
K. G. Lee, X. W. Chen, H. Eghlidi +5
Single emitters have been considered as sources of single photons in various contexts such as cryptography, quantum computation, spectroscopy, and metrology. The success of these a…
Resolution and enhancement in nanoantenna-based fluorescence microscopy
Hadi Eghlidi, Kwang Geol Lee, Xue-Wen Chen +2
Single gold nanoparticles can act as nanoantennas for enhancing the fluorescence of emitters in their near-fields. Here we present experimental and theoretical studies of scanning…
