Pioneering pressure-quench protocol for ambient-pressure superconductors

Scientists just cracked a problem that's plagued superconductor research for decades: how to make these wonder materials work without crushing them under diamond-anvil pressures. In February 2025, teams at SLAC and Stanford stabilized nickelate superconductors at everyday pressure using substrate compression, while University of Houston researchers locked in a superconducting state using a rapid pressure-release technique. Both still require ultra-cold temperatures, but eliminating the pressure constraint opens the door to real experiments—and eventually, to lossless power grids and fault-tolerant quantum computers.
