Will the measurement of a qubit destroy its quantum superposition?
In the realm of quantum mechanics, a qubit represents the fundamental unit of quantum information, analogous to the classical bit. Unlike classical bits, which can exist in either a state of 0 or 1, qubits can exist in a superposition of both states simultaneously. This unique property is at the core of quantum computing and
