Quantum Particles Can Flow Backward ⚡ экспресс
Original: "General quantum backflow in realistic wave packets"
A new approach allows particles to move backward nearly three times more often — up to a 13% probability.

Quantum backflow is when a particle moves backward even though its momentum points forward. Previously, the limit was 4%, but a new approach raises the bar to nearly 13%. It's like a crowd where every seventh person is walking against the flow. This effect will simplify experiments and could be useful in nanotechnology.
🎯 Backflow is one of the most elusive effects in quantum mechanics. Although it follows from the equations, it hasn't been directly observed in almost a hundred years.
