Published the study as open access
The intrinsic current limit of a superconductor — the point where Cooper pairs tear apart — has been known theoretically for decades but never measured directly. Vortex motion and self-heating always destroyed the supercurrent first. A team at the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg has now bypassed both by firing picosecond electrical pulses, far too short for vortices to move.

Publication venue for the quadsqueezing result
Physicists at the University of Oxford have generated a quantum interaction that existed only on paper until now. Using a single trapped ion and two carefully tuned forces, the team produced 'quadsqueezing'—a fourth-order quantum-squeezing effect—more than 100 times faster than conventional methods predicted should be possible.
