User provided error values that override machine values for emulation of Quantinuum Systems hardware.

See the Quantinuum Systems documentation for details of each parameter.

Args:

p1: Probability of a fault occurring during a 1-qubit gate. p2: Probability of a fault occurring during a 2-qubit gate. p_meas:

Probability of a bit flip being applied to a measurement. Either a float or a tuple of 2 floats. If it is a single float then that error rate is used to bitflip both 0 and 1 measurement results. If a tuple is supplied, the first element is the probability a bit flip is applied if a 0 result occurs during measurement while the second error rate if a 1 is measured.

p_init: Probability of a fault occurring during initialization of a qubit. p_crosstalk_meas: Probability of a crosstalk measurement fault occurring. p_crosstalk_init: Probability of a cross-talk fault occurring during initialization of a

qubit.

p1_emission_ratio: Fraction of p1 that is spontaneous emission for a single qubit instead

of asymmetric depolarizing noise.

p2_emission_ratio: Fraction of p2 that is spontaneous emission for a 1- qubit in a 2-qubit

gate instead of asymmetric depolarizing noise.

quadratic_dephasing_rate: The frequency, f, in applying RZ(fd)during transport and idling. linear_dephasing_rate: The probability of applying Z with p=rd where r is rate and

d is duration. This models the memory error. Note both the quadratic and linear term can be applied in the same simulation.

coherent_to_incoherent_factor: A multiplier on the quadratic term when running stabilizer

simulations to attempt to account for increases in error due to coherent effects in the circuit.

coherent_dephasing: A boolean value determining whether quadratic dephasing is applied. transport_dephasing: A boolean affecting whether memory noise is applied during transport. idle_dephasing: A boolean affecting if memory noise is applied due to qubit idling. przz_a: Parameter a in parameterized angle scaling. See Emulator User Guide for details. przz_b: Parameter b in parameterized angle scaling. See Emulator User Guide for details. przz_c: Parameter c in parameterized angle scaling. See Emulator User Guide for details. przz_d: Parameter d in parameterized angle scaling. See Emulator User Guide for details. przz_power: Polynomial power in parameterized angle scaling. See Emulator User Guide for

details.

scale: Scale all error rates in the model linearly. p1_scale: Scale the probability of a fault occurring during a 1-qubit gate. p2_scale: Scale the probability of a fault occurring during a 2-qubit gate. meas_scale: Scale the probability of a fault occurring during measurement. init_scale: Scale the probability of a fault occurring during initialization of a qubit. memory_scale: Linearly scale the probability of dephasing causing a fault. emission_scale: Scale the probability that a spontaneous emission event happens during a

1- or 2-qubit gate.

crosstalk_scale: Scale the probability that measurement or initialization crosstalk events

get applied to qubits. During mid-circuit measurement and reset (initialization), crosstalk noise can occur that effectively measures other qubits in the trap or cause them to leak.

leakage_scale: Scale the probability that a leakage even happens during 1- or 2-qubit

gates as well as during initialization or crosstalk; on the device half the time, spontaneous emission leads to a leakage event.
