Bases: ConstantOp
The \(P_0\) projection operator.
\[
P0 = \begin{bmatrix} 1 & 0 \\ 0 & 0 \end{bmatrix}
\]
Bases: ConstantOp
The \(P_1\) projection operator.
\[
P1 = \begin{bmatrix} 0 & 0 \\ 0 & 1 \end{bmatrix}
\]
Bases: PrimitiveOp
A phase operator.
\[
\text{PhaseOp}(\theta) = e^{i \theta} I
\]
Bases: PrimitiveOp
Reset operator for qubits and wires.
Bases: PrimitiveOp
Reset qubits to the one state. Mainly needed to accommodate cirq's GeneralizedAmplitudeDampingChannel
Bases: PrimitiveOp
A phase shift operator.
\[
\text{Shift}(\theta) = \begin{bmatrix} 1 & 0 \\ 0 & e^{i \theta} \end{bmatrix}
\]
Bases: ConstantOp
\(S_{-}\) operator.
\[
Sn = \frac{1}{2} (S_x - i S_y) = \frac{1}{2} \begin{bmatrix} 0 & 0 \\ 1 & 0 \end{bmatrix}
\]
Bases: ConstantOp
\(S_{+}\) operator.
\[
Sp = \frac{1}{2} (S_x + i S_y) = \frac{1}{2}\begin{bmatrix} 0 & 1 \\ 0 & 0 \end{bmatrix}
\]
Bases: PrimitiveOp
The rotation operator U3(theta, phi, lam). Note that we use the convention from the QASM2 specification, namely
\[
U_3(\theta, \phi, \lambda) = R_z(\phi) R_y(\theta) R_z(\lambda)
\]
