Pauli Z gate
Installation Required: This functionality requires MATLAB Support Package for Quantum Computing.
Pauli Z Gate and Its Matrix Representation
Create a Pauli Z gate that acts on a single qubit.
g = zGate(1)
g = SimpleGate with properties: Type: "z" ControlQubits: [1×0 double] TargetQubits: 1 Angles: [1×0 double]
Get the matrix representation of the gate.
M = getMatrix(g)
M = 1 0 0 -1
Array of Pauli Z Gates
Create an array of Pauli Z gates that act on qubits with indices 1 to 4.
g = zGate(1:4)
g = 4×1 SimpleGate array with gates: Id Gate Control Target 1 z 1 2 z 2 3 z 3 4 z 4
targetQubit — Target qubit of gate
positive integer scalar | positive integer vector
Target qubit of the gate, specified as a positive integer scalar index or vector of qubit indices.
Matrix Representation of Pauli Z Gate
The matrix representation of a Pauli Z gate applied to a single qubit is
This gate leaves the state as is and maps the state to . This gate is also known as a phase-flip gate.
