Noise That Helps: A Quantum 'Pendulum' on a Chip ⚡ экспресс
Original: "Noise-stabilized discrete time crystals on digital quantum processors"
Errors on an IBM quantum chip helped create a stable time crystal — rhythmic oscillations that never fade.

Noise, which usually disrupts quantum systems, played the role of a conductor on the IBM chip: it made the 'pendulum' swing longer, creating a semblance of perpetual ticking. This trick could make quantum computers more stable by turning errors from foes into allies.
🎯 The concept of time crystals was first proposed by physicist [scientist:Frank Wilczek]Frank Wilczek[/scientist] in 2012, and at first many thought it contradicted the laws of physics.
🎬 The idea of time crystals echoes sci-fi plots about time machines or perpetual motion machines, but in reality they need periodic energy input.
