class QbNoiseModel : public qb::NoiseModel 

QB Noise Model: Noise model of QB’s NV quantum devices.

Public Types

enum class Generation

Enum to denote noise model generation.

Values:

enumerator nm1

enumerator nm2

enumerator qdk1

Public Functions

QbNoiseModel(Generation gen = Generation::nm2)

Construct a new Qb Noise Model object.

Parameters: gen – Specifies the noise model generation

QbNoiseModel(Generation gen, double t1_ns, double t2_ns)

Construct a new Qb Noise Model object.

Attention: This is for testability only whereby we allow for variation to T1 and T2 value to verify the noise model.

Parameters

gen – Specifies the noise model generation
t1_ns – T1 value to set (in nanoseconds)
t2_ns – T2 value to set (in nanoseconds)

QbNoiseModel(Generation gen, double t1_ns, double t2_ns, double single_qubit_gate_error, double two_qubit_gate_error)

Construct a new Qb Noise Model object IMPORTANT: This is for testability only whereby we allow for variation to T1, T2, and gate error value to verify the noise model.

Parameters

gen – Specifies the noise model generation
t1_ns – T1 value to set (in nanoseconds)
t2_ns – T2 value to set (in nanoseconds)
single_qubit_gate_error – single qubit gate error (prob between 0 and 1)
two_qubit_gate_error – two qubit gate error (prob between 0 and 1)

NoiseProperties::ReadoutError get_ro_errors(size_t qubit) const

Get the ro errors of a qubit.

Parameters: qubit – Qubit index
Returns: Readout errors

inline NoiseProperties &get_noise_props()

Get the noise props object.

Returns: NoiseProperties associated with the noise model.
