Near-Optimal Variance-Based Uncertainty Relations
Frontiers in Physics, 2022 Learning physical properties of a quantum system is essential for the developments of quantum technologies. However, Heisenberg’s uncertainty principle constrains the potential knowledge one can simultaneously have about a system in quantum theory. Aside

Phenolic Contents of Different Potato Genotypes Grown in the Central Northern Region in Turkey
Turkish Journal of Agriculture: Food Science and Technology, 2021 Potato (Solanum tuberosum L.) is one of the most significant vegetable crops for humans along with corn, wheat, and rice. In this study, quantitative analysis of phenolic compounds was carried out for 21 promising potato clones and three commercial ...

Non-Perturbative Theory for Dispersion Self-Energy of Atoms [PDF]
, 2014 We go beyond the approximate series-expansions used in the dispersion theory of finite size atoms. We demonstrate that a correct, and non-perturbative, theory dramatically alters the dispersion selfenergies of atoms.

Quantum error correction for continuously detected errors with any number of error channels per qubit [PDF]
, 2004 It was shown by Ahn, Wiseman, and Milburn [PRA {\bf 67}, 052310 (2003)] that feedback control could be used as a quantum error correction process for errors induced by weak continuous measurement, given one perfectly measured error channel per qubit ...

Phase-noise protection in quantum-enhanced differential interferometry
New Journal of Physics, 2014 Differential interferometry (DI) with two coupled sensors is a most powerful approach for precision measurements in the presence of strong phase noise. However, DI has been studied and implemented only with classical resources.

Long-range correlation of thermal radiation [PDF]
, 1998 A general theory is presented for the spatial correlations in the intensity of the radiation emitted by a random medium in thermal equilibrium. We find that a non-zero correlation persists over distances large compared to the transverse coherence length ...

DC field induced enhancement and inhibition of spontaneous emission in a cavity [PDF]
, 2003 We demonstrate how spontaneous emission in a cavity can be controlled by the application of a dc field. The method is specially suitable for Rydberg atoms. We present a simple argument for the control of emission.Comment: 3-pages, 2figure.

Thermal photon statistics in laser light above threshold [PDF]
, 1999 We show that the reduction in photon number fluctuations at laser threshold often cited as a fundamental laser property does not occur in typical semiconductor lasers such as the ones commonly used in modern technological applications today. Indeed, such
