Spectral analysis of spin noise in an optically spin-polarized stochastic Bloch equation driven by noisy magnetic fields

M. M. Kim, Sangkyung Lee

We provide a closed-form autocorrelation function and power spectral density (PSD) of the solution, along a prescribed probing direction, to a noisy version of an optically pumped…

Noise-robust single-pixel imaging in photon counting regime with a pulsed source

Junghyun Kim, Sangkyung Lee, Yonggi Jo +6

We present a method to classically enhance noise-robustness of single-pixel imaging in photon counting regime with a pulsed source. By using time-domain cross-correlations between…

Heralded single-pixel imaging with high loss-resistance and noise-robustness

Junghyun Kim, Taek Jeong, Su-Yong Lee +6

Imaging with non-classically correlated photon-pairs takes advantages over classical limits in terms of sensitivity and signal-to-noise ratio. However, it is still a challenge to a…

Quantum illumination receiver using double homodyne detection

Yonggi Jo, Sangkyung Lee, Yong Sup Ihn +2

A quantum receiver is an essential element of quantum illumination (QI) which outperforms its classical counterpart, called classical-illumination (CI). However, there are only few…

Cancellation of Collisional Frequency Shifts in Optical Lattice Clocks with Rabi Spectroscopy

Sangkyung Lee, Chang Yong Park, Won-Kyu Lee +1

We analyze both the s- and p-wave collision induced frequency shifts and propose a over- pulse scheme to cancel the shifts in optical lattice clocks interrogated by a Rabi pulse…

Optical repumping of triplet -states enhances magneto-optical trapping of ytterbium atoms

Jun Woo Cho, Han-gyeol Lee, Sangkyung Lee +5

Radiative decay from the excited state to metastable and states is expected to limit attainable trapped atomic population in a magneto-optic trap of ytterbi…

Coherent transients mimicked by two-photon coherent control of a three-level system

Jongseok Lim, Jae-uk Kim, Sangkyung Lee +1

We show that two-photon coherent control in a -shape three-level system projects one-photon coherent transient in a simple two-level system. Higher order chirps of a shaped lase…

Nonlocality improves Deutsch algorithm

Koji Nagata, Sangkyung Lee, Jaewook Ahn

Recently, [{arXiv:0810.3134}] is accepted and published. We show that the Bell inequalities lead to a new type of linear-optical Deutsch algorithms. We have considered a use of ent…
