Definition: Quantum time refers to a state or measurement of time that differs from classical physics, where particles have an exact duration defined by their mass. It's often used in quantum mechanics to describe phenomena like superposition, entanglement, and decoherence. Definition: "Quantum time" is the concept of measuring something as if it has a finite duration in contrast to classical physics, which only specifies its duration. This extends our understanding of time beyond that found in Newtonian mechanics.
