YGate

The Pauli Y gate.

This causes a bit flip (with a complex phase): Y|0> = 1j|1>, Y|1> = -1j|0>

Registers

• q: The qubit.

from qualtran.bloqs.basic_gates import YGate

Example Instances

y_gate = YGate()

Graphical Signature

from qualtran.drawing import show_bloqs
show_bloqs([y_gate],
           ['`y_gate`'])

show_bloq(y_gate, 'musical_score')

CYGate

A controlled Y gate.

Registers

• ctrl: The control qubit.

• target: The target qubit.

from qualtran.bloqs.basic_gates import CYGate

Example Instances

cy_gate = YGate().controlled()
assert isinstance(cy_gate, CYGate)

Graphical Signature

from qualtran.drawing import show_bloqs
show_bloqs([cy_gate],
           ['`cy_gate`'])

show_bloq(cy_gate, 'musical_score')
