RepetitionCode

class RepetitionCode(d, T=0, xbasis=False, resets=False, delay=0)

Bases: object

Implementation of a distance d repetition code, implemented over T syndrome measurement rounds.

Creates the circuits corresponding to a logical 0 and 1 encoded using a repetition code.

Parameters

• d (int) -- Number of code qubits (and hence repetitions) used.

• T (int) -- Number of rounds of ancilla-assisted syndrome measurement.

• xbasis (bool) -- Whether to use the X basis to use for encoding (Z basis used by default).

• resets (bool) -- Whether to include a reset gate after mid-circuit measurements.

• delay (float) -- Time (in dt) to delay after mid-circuit measurements (and delay).

Additional information:

No measurements are added to the circuit if T=0. Otherwise T rounds are added, followed by measurement of the code qubits (corresponding to a logical measurement and final syndrome measurement round).

Methods

get_circuit_list	returns self.circuit as a list, with
process_results	param raw_results A dictionary whose keys are logical values,
readout	Readout of all code qubits, which corresponds to a logical measurement as well as allowing for a measurement of the syndrome to be inferred.
syndrome_measurement	Application of a syndrome measurement round.
x	Applies a logical x to the circuits for the given logical values.
