Exploring parameter shift for quantum Fisher information

In a recent publication in EPJ Quantum Technology, Le Bin Ho from Tohoku University's Frontier Institute for Interdisciplinary Sciences has developed a technique called time-dependent stochastic parameter shift in the realm ...

Uncovering universal physics in the dynamics of a quantum system

New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws the system out of equilibrium. ...

Quantum chemistry: Molecules caught tunneling

Tunneling reactions in chemistry are difficult to predict. The quantum mechanically exact description of chemical reactions with more than three particles is difficult, with more than four particles it is almost impossible. ...

Non-inertial torques and the Euler equation

Classical mechanics is the framework for studying motion of objects under the influence of forces. Its domain of applicability is limited to the macroscopic world (i.e., not applicable in the atomic/subatomic world) and to ...
