Physicists working on the ATLAS experiment at CERN have observed entanglement between pairs of top quarks for the first time. The finding demonstrates that entanglement can occur at energies more than 12 orders of magnitude higher than is typical for laboratory entanglement experiments. They also show that particle-physics facilities such as CERN’s Large Hadron Collider (LHC) can be used to study quantum mechanics and quantum information.

Physics World: Scalable quantum processor simulates non-equilibrium phase transitions
A 20-qubit quantum processor has been used to simulate the classical and quantum nature of non-equilibrium phase transitions. The work was done by researchers in the US and Canada, who used a processor made by Quantinuum, which is based in the UK and US. The team’s success suggests that small-scale quantum processors could soon be solving some problems that are beyond the capability of conventional computers – an achievement called quantum advantage. This advantage could be put to use in fields including condensed matter, quantum optics and metrology.
