It is well known that the quantum fluctuation of entanglement(QFE) between Unruh–De Witt detector(modeled by a two-level atom) is always investigated in a rela
We simulate pulse shaping of bright-dark vector soliton pair in an optical fiber system.Through changing input pulse parameters(amplitude ratio,projection angle
We demonstrate a 300-km+200-km cascaded coherent phase transfer via fiber link.The transfer is divided into a 300-km span and a 200-km span with independent pha
