tqec.circuit.qubit_map.QubitMap#

class QubitMap(i2q: dict[int, ~tqec.circuit.qubit.GridQubit] = <factory>)[source]#

Represent a bijection between GridQubit instances and indices.

This class aims at representing a bidirectional mapping (hence the “bijection”) between qubits and their associated indices.

Raises:: TQECException – if the provided mapping from indices to qubits is not a bijection (i.e., if at least to values represent the same qubit).

__init__(i2q: dict[int, ~tqec.circuit.qubit.GridQubit] = <factory>) → None#

Methods

`__init__`([i2q])
`filter_by_qubits`(qubits_to_keep)	Filter the qubit map to only keep qubits present in the provided qubits_to_keep.
`from_circuit`(circuit)
`from_qubits`(qubits)	Creates a qubit map from the provided qubits, associating indices using the order in which qubits are provided.
`items`()
`to_circuit`()	Get a circuit with only QUBIT_COORDS instructions representing self.
`with_mapped_qubits`(qubit_map)	Change the qubits involved in self without changing the associated indices.
