qualtran.surface_code.PhysicalParameters(
    physical_error=attr_dict['physical_error'].default,
    cycle_time_us=attr_dict['cycle_time_us'].default
)

Attributes

physical_error

The error rate of the underlying physical qubits.

cycle_time_us

The number of microseconds it takes to do one cycle of error correction.

Methods

View source

@classmethod
make_beverland_et_al(
    qubit_modality: str = 'superconducting',
    optimistic_err_rate: bool = False
)

The physical parameters considered in the Beverland et al. reference.

Args

qubit_modality

One of “superconducting”, “ion”, or “majorana”. This sets the cycle time, with ions being considerably slower.

optimistic_err_rate

In the reference, the authors consider two error rates, which they term “realistic” and “optimistic”. Set this to True to use optimistic error rates.
