Definition

A quantum mechanics concept defining a model element, mathematical object, or experimental method used to predict measurable outcomes. It applies when required assumptions and definitions are specified and yields computable probabilities and expectation values. It does not ensure correctness without validation of approximations, numerical stability, and consistency of units and conventions.

Definition

A class of coherent control pulse-sequence methods that suppress unwanted system–environment interactions by applying sequences of rapid unitary operations (pulses or modulations) so that the effective interaction Hamiltonian averages toward zero over the control cycle, thereby extending the system's coherent lifetime under appropriate noise spectra.
