Digital Quantum Simulation and Circuit Learning for the Generation of Coherent States
Ruilin Liu, Sebastián V. Romero, Izaskun Oregi +3
Coherent states, known as displaced vacuum states, play an important role in quantum information processing, quantum machine learning,and quantum optics. In this article, two ways…
Tighter monogamy relations of entanglement measures based on fidelity
Meiming Zhang, Naihuan Jing
We study the Bures measure of entanglement and the geometric measure of entanglement as special cases of entanglement measures based on fidelity, and find their tighter monogamy in…
Dynamics of a quantum wave emitted by a decaying and evanescent point source
F. Delgado, J. G. Muga
We put forward a model that describes a decaying and evanescent point source of non-interacting quantum waves in 1D. This point-source assumption allows for a simple description th…
Separability criteria based on the Weyl operators
Xiaofen Huang, Tinggui Zhang, Ming-Jing Zhao +1
Entanglement as a vital resource for information processing can be described by special properties of the quantum state. Using the well-known Weyl basis we propose a new Bloch deco…
Optimizing Counterdiabaticity by Variational Quantum Circuits
Dan Sun, Pranav Chandarana, Zi-Hua Xin +1
Utilizing counterdiabatic (CD) driving - aiming at suppression of diabatic transition - in digitized adiabatic evolution have garnered immense interest in quantum protocols and alg…
Robust control of linear systems and shortcut to adiabaticity based on superoscillations
Qi Zhang, Xi Chen, David Guéry-Odelin
With the advent of quantum technologies, control issues are becoming increasingly important. In this article, we address the control in phase space under a global constraint provid…
