Scientists simulated a magnetic material with a kagome pattern on a quantum computer. They found that noise from extra qubits doesn't disrupt but actually prolongs periodic oscillations (a time crystal), and sometimes even creates them. This is a way to control quantum states using unavoidable error

On an IBM quantum processor, scientists cyclically rotated 28 quantum tops. Without any external force, their spinning synchronized. A symmetry, like a hidden rule, protected this rhythm. With 156 tops, some synchronized while the rest spun chaotically—a quantum chimera paving the way to ultra-stabl

Quantum systems usually quickly forget their initial state, but physicists found a way to slow this process. On an IBM processor, 144 qubits evolved for 5000 cycles, and entropy — a measure of disorder — grew so slowly it resembled a black hole evaporating in slow motion. This proves the ability to
