QubitProp

cqlib_core::device::device_impl

Struct QubitProp 

Source 
pub struct QubitProp { /* private fields */ }
Expand description

Represents the physical and operational properties of a single quantum qubit.

This includes coherence metrics (T1 relaxation time, T2 dephasing time), operational frequency, and measurement error rates. It also maintains a list of InstructionProp which defines the specific native single-qubit instructions supported by this qubit along with their calibrated fidelities and durations.
