-
class
RepetitionCode(d, T=0)[ソース]¶ 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.
- パラメータ
d (int) – Number of code qubits (and hence repetitions) used.
T (int) – Number of rounds of ancilla-assisted syndrome measurement.
- 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).
-
__init__(d, T=0)[ソース]¶ Creates the circuits corresponding to a logical 0 and 1 encoded using a repetition code.
- パラメータ
d (int) – Number of code qubits (and hence repetitions) used.
T (int) – Number of rounds of ancilla-assisted syndrome measurement.
- 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
__init__(d[, T])Creates the circuits corresponding to a logical 0 and 1 encoded using a repetition code.
- returns
self.circuit as a list, with
process_results(raw_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([reset, barrier])Application of a syndrome measurement round.
x([logs, barrier])Applies a logical x to the circuits for the given logical values.

get_circuit_list()[ソース]¶ - 戻り値
self.circuit as a list, with circuit_list[0] = circuit[『0』] circuit_list[1] = circuit[『1』]

process_results(raw_results)[ソース]¶ - パラメータ
raw_results (dict) – A dictionary whose keys are logical values, and whose values are standard counts dictionaries, (as obtained from the get_counts method of a
qiskit.Resultobject).- 戻り値
- Dictionary with the same structure as the input, but with
the bit strings used as keys in the counts dictionaries converted to the form required by the decoder.

results
- Additional information:
The circuits must be executed outside of this class, so that their is full freedom to compile, choose a backend, use a noise model, etc. The results from these executions should then be used to create the input for this method.

readout()[ソース]¶ Readout of all code qubits, which corresponds to a logical measurement as well as allowing for a measurement of the syndrome to be inferred.
