No pairs: the first ‘open flavour’ tetraquark has been spotted at CERN (Courtesy: Shutterstock/paul_june) The first tetraquark composed of four quarks of different flavours has been discovered by physicists working on the LHCb experiment at CERN. Dubbed X(2900), the “open flavour” tetraquark has a mass of about 2.9 GeV/c2 and has been spotted in two spin

Party line: the new protocol allows 10 parties to share information securely. (Courtesy: University of Witwatersrand) A “quantum secret sharing” scheme that allows 10 parties share information securely – the highest number so far – has been developed and demonstrated by researchers in South Africa. The protocol involves each party performing quantum operations on the photon without

Courtesy: Chinese Physics Letters In 2019, researchers discovered that two intrinsically magnetic materials, MnBi2Te4 and MnBi2Te7, can behave as topological insulators – materials that are electrically insulating in bulk, but conduct electricity well on the surface. A team led by Yangpeng Qi from ShanghaiTech University has
