Entropic uncertainty relation under quantum channels with memory [PDF]
arXiv, 2017 Recently, Xu et al. [Phys. Rev. A 86, 012113(2012)] explored the behavior of the entropic uncertainty relation under the influence of local unital and nonunital noisy channels for a class of Bell-diagonal states. We here reform their results and investigate the entropic uncertainty relation under the influence of unital and nonunital noisy channels ...

Channel-Adapted Quantum Error Correction [PDF]
—Error correction procedures are considered which are designed specifically for the amplitude damping channel. Amplitude damping errors are analyzed in the stabilizer formalism. This analysis allows a generalization of the [4; 1] “approximate ” amplitude

Advanced Science, EarlyView.This study prepares copper tungstate (CuWO4, CWO) nanoparticles for synergistic sono‐enhanced cuproptosis‐based cancer therapy. With an ultrasmall bandgap (1.71 eV), CWO facilitates efficient charge carrier separation under ultrasound, enhancing the generation of reactive oxygen species and the controlled release of Cu2+ ions cascade amplify oxidative ...

Self‐Oscillation in Active Wires with Asymmetric Willis‐Type Viscosity
Advanced Science, EarlyView.This study suggests a self‐oscillation strategy enabled by a new set of material parameters, namely the asymmetric Willis‐type viscosity, to bias and independently control oscillation mode shapes as well as frequencies. The exemplified active wire can benefit the development of autonomous materials to construct soft motors, agitators, pumps, and ...

Preserving information from the beginning to the end of time in a Robertson–Walker spacetime
New Journal of Physics, 2014 Preserving information stored in a physical system subjected to noise can be modeled in a communication-theoretic paradigm, in which storage and retrieval correspond to an input encoding and output decoding, respectively.

Advanced Science, EarlyView.A series of oxygen‐enhanced Zr‐Hf‐Ti‐Nb MPEAs with high strength and outstanding damping capacity are developed through tailoring the BCC structural stability by an elaborate composition regulation. Strengthening mechanism for high strength and damping mechanism related to various Snoek‐type relaxations reveals that the existence of multiple separate O‐
