Magnetic 'Headphones' for Qubits: A New Way to Fight Quantum Noise ⚡ экспресс
Original: "Beyond the Purcell Effect: Controlling Pure Quantum Dephasing with Spin Noise Metasurfaces"
Scientists have devised ultra-thin magnetic patterns that act like noise-canceling headphones, shielding quantum bits from harmful magnetic interference.

Picture an ultra-thin magnetic film that works as a noise-suppressing screen for quantum bits. A properly engineered nanopattern slows the disintegration of quantum information by an order of magnitude, bringing quantum computers closer to reality.
🎯 Paradoxically, the magnetic alloy CoFeB used in regular films actually speeds up quantum state decay. But with a cleverly designed nanopattern, it transforms into a shield, effectively soaking up stray magnetic fields.
