Quantum Spin Defies Classical Physics, Enabling New Quantum Tech

Physicists have demonstrated that the precession of a nuclear spin can deviate from classical physics under specific conditions. This discovery, achieved by researchers using a single antimony nucleus (Sb-123) implanted in a silicon chip, confirms that the spin of an atomic nucleus is a quantum phenomenon. The team measured the spin's orientation at seven points during each rotation and found that the probability of finding the spin in a positive direction exceeded classical limits, reaching 0.636 against an expected 0.571. This indicates the spin exists in a quantum superposition state, behaving as if it were in two opposing orientations simultaneously, akin to a Schrödinger's cat state. This breakthrough, achieved in [Country] on [Date], not only challenges established physics but also opens avenues for quantum computing, quantum sensors, and advanced quantum technologies by providing a method to certify and manipulate quantum states directly.
