no code implementations • 22 Jan 2021 • Tao Peng, Xingchen Zhao, Yanhua Shih, Marlan O. Scully

We propose and demonstrate a method for measuring the time evolution of the off-diagonal elements $\rho_{n, n+k}(t)$ of the reduced density matrix obtained from the quantum theory of the laser.

Non-invasive imaging of object behind strongly scattering media via cross-spectrum

no code implementations • 11 Dec 2020 • Xingchen Zhao, Tao Peng, Zhenhuan Yi, Lida Zhang, M. Suhail Zubairy, Yanhua Shih, Marlan O. Scully

We develop a method based on the cross-spectrum of an intensity-modulated CW laser, which can extract a signal from an extremely noisy environment and image objects hidden in turbid media.
