Chinese physicist Pan Jianwei and his team have created a “quantum Lego block” that refuses to fall apart – even when shaken.
Using a programmable quantum processor named Zuchongzhi 2, Pan’s team has simulated an exotic new state of matter where quantum effects are locked into the corners of a material, according to a paper published in the peer-reviewed journal Science on Friday. These corner states are protected by the deep laws of topology – a kind of quantum armour against errors and…
