Detailed Description

template<typename Time = Types::time_type>
class Circuits::Delay< Time >

Delay (idle) operation class.

Represents a physical delay or idling period on a target qubit with duration tau. In ideal noiseless simulation, it acts as an identity operation. In noisy simulation, it triggers wall-clock thermal relaxation, continuous Ornstein-Uhlenbeck dephasing, and coherent detuning rotation.

Template Parameters

Time	The time type used for operation timing.
