Twice Around To Return Home: Hidden Reset Button For Spins And Qubits
Introduction: A Hidden Reset Button in Rotations Rotations govern a vast array of physical systems, from classical gyroscopes to quantum qubits. In three dimensions, the mathematical language describing these motions is the rotation group SO(3) for classical objects and its quantum counterpart SU(2). A striking and practical insight emerges when we consider walks through these…
