# cirq.Moment¶

class cirq.Moment(operations: Iterable[cirq.ops.raw_types.Operation] = ())[source]

A simplified time-slice of operations within a sequenced circuit.

Note that grouping sequenced circuits into moments is an abstraction that may not carry over directly to the scheduling on the hardware or simulator. Operations in the same moment may or may not actually end up scheduled to occur at the same time. However the topological quantum circuit ordering will be preserved, and many schedulers or consumers will attempt to maximize the moment representation.

operations

A tuple of the Operations for this Moment.

qubits

A set of the qubits acted upon by this Moment.

__init__(operations: Iterable[cirq.ops.raw_types.Operation] = ()) → None[source]

Constructs a moment with the given operations.

Parameters: operations – The operations applied within the moment. Will be frozen into a tuple before storing. ValueError – A qubit appears more than once.

Methods

 operates_on(qubits) Determines if the moment has operations touching the given qubits. with_operation(operation) Returns an equal moment, but with the given op added. without_operations_touching(qubits) Returns an equal moment, but without ops on the given qubits.
