Proof-of-randomness protocol for blockchain consensus: a case of Macau algorithms
Wen-Zhuo Zhang, Victor Kai
A proof-of-randomness (PoR) protocol is presented as a fair and low energy-cost consensus mechanism for blockchains. Each network node of a blockchain may use a true random number…
Ground test of satellite constellation based quantum communication
Sheng-Kai Liao, Hai-Lin Yong, Chang Liu +22
Satellite based quantum communication has been proven as a feasible way to achieve global scale quantum communication network. Very recently, a low-Earth-orbit (LEO) satellite has…
Measurement-enhanced determination of BEC phase transitions
Mark G. Bason, Robert Heck, Mario Napolitano +6
We demonstrate how dispersive atom number measurements during evaporative cooling can be used for enhanced determination of the parameter dependence of the transition to a Bose-Ein…
Enhanced cooling of rubidium atoms in two-frequency diffuse lights
Wen-Zhuo Zhang, Hua-Dong Cheng, Ling Xiao +2
In this paper we describe an experiment of efficient cooling of Rb atoms in two-frequency diffuse laser lights. Compared with single frequency diffuse light, two-frequency d…
