cirq.q

Constructs a qubit id of the appropriate type based on args.

cirq.q(
    *args
) -> Union['cirq.LineQubit', 'cirq.GridQubit', 'cirq.NamedQubit']

Used in the notebooks

Used in the tutorials

This is shorthand for constructing qubit ids of common types:

>>> cirq.q(1) == cirq.LineQubit(1)
True
>>> cirq.q(1, 2) == cirq.GridQubit(1, 2)
True
>>> cirq.q("foo") == cirq.NamedQubit("foo")
True

Note that arguments should be treated as positional only.

*args One or two ints, or a single str, as described above.

cirq.LineQubit if called with one integer arg. cirq.GridQubit if called with two integer args. cirq.NamedQubit if called with one string arg.

ValueError if called with invalid arguments.
