内容: The Szilard engine (SZE) is the quintessence of Maxwell’s demon, which can extract the work from a heat bath by utilizing information. We present the first complete quantum analysis of the SZE...
内容: We realize a photonic analog simulator of the quantum Rabi model, based on light transport in femtosecond-laser-written waveguide superlattices, which provides an experimentally accessible test...
内容: The Bloch sphere is a generic picture describing the coherent dynamics of coupled classical or quantum-mechanical twolevel systems under the control of electromagnetic fields1,2. It is commonly...
内容: All evidence so far suggests that the absolute spatial orientation of an experiment never affects its outcome. This is reflected in the standard model of particle physics by requiring all parti...
内容: The key to explaining and controlling a range of quantum phenomena is to study how information propagates around many-body systems. Quantum dynamics can be described by particle-like carriers o...
内容: With the advent of quantum information, the violation of a Bell inequality is used to witness the absence of an eavesdropper in cryptographic scenarios such as key distribution and randomness e...
