Machine Learning Enhanced Quantum State Tomography on FPGA
Hsun-Chung Wu, Hsien-Yi Hsieh, Zhi-Kai Xu +7
Machine learning techniques have opened new avenues for real-time quantum state tomography (QST). In this work, we demonstrate the deployment of machine learning-based QST onto edg…
Generation of heralded optical `Schroedinger cat' states by photon-addition
Yi-Ru Chen, Hsien-Yi Hsieh, Jingyu Ning +7
Optical "Schrödinger cat" states, the non-classical superposition of two quasi-classical coherent states, serve as a basis for gedanken experiments testing quantum physics on mesos…
Experimental Demonstration of Topological Charge Protection in Wigner Current
Yi-Ru Chen, Hsien-Yi Hsieh, Jingyu Ning +7
We experimentally reconstruct Wigner's current of quantum phase space dynamics for the first time. We reveal the ``push-and-pull" associated with damping and diffusion due to the c…
On the Formation of Lines in Quantum Phase Space
Ole Steuernagel, Popo Yang, Ray-Kuang Lee
We study the formation of lines in phase space in Wigner's distribution Whereas lines in phase space do not form in classical systems, unless special initial states are chosen…
The Wigner flow on the sphere
P. Yang, I. F. Valtierra, A. B. Klimov +4
We derive a continuity equation for the evolution of the SU(2) Wigner function under nonlinear Kerr evolution. We give explicit expressions for the resulting quantum Wigner current…
Phase space representation of non-Hermitian system with -symmetry
Ludmila Praxmeyer, Popo Yang, Ray-Kuang Lee
We present a phase space study of non-Hermitian Hamiltonian with -symmetry based on the Wigner distribution function. For an arbitrary complex potential, we derive a…
Direct Measurement of Time-Frequency Analogues of Sub-Planck Structures
Ludmila Praxmeyer, Chih-Cheng Chen, Popo Yang +2
Exploiting the correspondence between Wigner distribution function and a frequency-resolved optical gating (FROG) measurement, we experimentally demonstrate existence of the chessb…
