Optical tomography dynamic for time-dependent coherent states generated by an open qubit-cavity system

open access: yesResults in Physics, 2021
Optical tomography is investigated for time-dependent quantum states, which are generated from coherent even and odd coherent cavity fields interacting with a two-level system (qubit) in the presence of phase damping.

Cross-Polarization Optical Coherence Tomography for Brain Tumor Imaging

open access: yesFrontiers in Oncology, 2019
This paper considers valuable visual assessment criteria for distinguishing between tumorous and non-tumorous tissues, intraoperatively, using cross-polarization OCT (CP OCT)—OCT with a functional extension, that enables detection of the polarization ...

Optical Coherence Tomography [PDF]

open access: yesScience, 1991
A technique called optical coherence tomography (OCT) has been developed for noninvasive cross-sectional imaging in biological systems. OCT uses low-coherence interferometry to produce a two-dimensional image of optical scattering from internal tissue microstructures in a way that is analogous to ultrasonic pulse-echo imaging.

Optical tomography dynamics induced by qubit-resonator interaction under intrinsic decoherence

open access: yesScientific Reports, 2022
A superconducting circuit with a qubit and a resonator coupled via a two-photon interaction is considered. When the resonator is initially in a superposition of coherent states, optical tomography and quantum coherence dynamics are examined in the ...
