The measure of how long a qubit maintains quantum state before decoherence is called ________ Time.

  1. Coherence
  2. Stratified
  3. Knowledge
  4. Kubernetes

Answer: Coherence

Coherence time (T1 for energy relaxation, T2 for phase decoherence) determines how many quantum operations can be performed before errors dominate. Longer coherence enables more complex algorithms.
