Heavy electrons in CeRhSn stay entangled for time approaching Planckian limit; effect may enable near room temperature quantum computers

"heavy fermions, electrons acting as if they carry far more mass than usual, stay entangled at near room temperature, for an amount of time approaching Planckian limit (the shortest time interval measurable in classical physics)... since effect appears at close to room temperature, it might be harnessed in solid-state materials for a new type of quantum computer which can operate at that temperature... control/ manipulation of quantum entanglement in solid-state materials like CeRhSn for novel quantum computing architectures"
