Quantum gates that are commonly used in the literature.
This module creates Gate instances for the following gates: X,Y,Z: Pauli gates. H,S: Clifford gates. T: A non-Clifford gate. CZ: Controlled phase gate. CNOT: Controlled not gate.
Each of these are implemented as EigenGates, which means that they can be raised to a power (i.e. cirq.H**0.5). See the definition in EigenGate.
Classes
class CNotPowGate: A gate that applies a controlled power of an X gate.
class CXPowGate: A gate that applies a controlled power of an X gate.
class CZPowGate: A gate that applies a phase to the |11⟩ state of two qubits.
class HPowGate: A Gate that performs a rotation around the X+Z axis of the Bloch sphere.
class Rx: A gate, with matrix e^{-i X rads/2}, that rotates around the X axis of the Bloch sphere.
class Ry: A gate, with matrix e^{-i Y rads/2}, that rotates around the Y axis of the Bloch sphere.
class Rz: A gate, with matrix e^{-i Z rads/2}, that rotates around the Z axis of the Bloch sphere.
class XPowGate: A gate that rotates around the X axis of the Bloch sphere.
class YPowGate: A gate that rotates around the Y axis of the Bloch sphere.
class ZPowGate: A gate that rotates around the Z axis of the Bloch sphere.
