The one-dimensional (1D) Bose gas model of particles interacting via a repulsive delta-function potential is a remarkable system for extending our understanding of the physics of interacting quantum many-body systems. On the one hand, the model is exactly solvable in quantum many-body theory. On the other hand, it is now experimentally realizable with ultra-cold alkali atoms in highly anisotrop...

An overlooked problem in Learning From Demonstration is the ambiguity that arises, for instance, when the robot is equipped with more sensors than necessary for a certain task. Simply trying to repeat all aspects of a demonstration is seldom what the human teacher wants, and without additional information, it is hard for the robot to know which features are relevant and which should be ignored....

Achieving high-precision detection of time-dependent signals in noisy environment is a ubiquitous issue physics and critical task metrology. Lock-in amplifiers are detectors that can extract alternating with known carrier frequency from an extremely environment. Here, we present protocol for achieving entanglement-enhanced lock-in amplifier via empoying many-body quantum interferometry periodic...
