Quantum logic gates are the building blocks of quantum circuits, like classical logic gates are for conventional digital circuits. Unlike many classical logic gates, quantum logic gates are reversible. It is possible to perform classical computing using only reversible gates.

Quantum gates like X, Y, and Z are fundamental operations used to manipulate qubits in quantum computing. They are analogous to classical logic gates but operate on quantum states, which can exist in superpositions.

Apr 13, 2020 · The Z-gate is a unitary gate that acts on only one qubit. Specifically it maps 1 to -1 and leaves 0 unchanged. It does this by rotating around the Z axis of the qubit by π radians (180 degrees).

Equivalent to a \pi π radian rotation about the Z axis. A global phase difference exists between the definitions of RZ(π) and Z. The gate is equivalent to a phase flip. Create new Z gate. Get the base class of this instruction. This is guaranteed to be in the inheritance tree of self.

Mar 20, 2024 · The Z gate, also known as the Pauli-Z gate, is a quantum gate that performs a phase flip on the quantum state it is applied. The Z gate has the effect of multiplying the quantum state by -1 if it is in the ‘one’ state and leaving it unchanged if it is in the ‘zero’ state.

May 15, 2020 · The Z-gate is a unitary gate that acts on only one qubit. Specifically it maps 1 to -1 and leaves 0 unchanged. It does this by rotating around the Z axis of the qubit by π radians (180 degrees).

We’ll begin by considering the action of a quantum gate on a single quantum bit. A single classical bit (cbit) is relatively boring; either it’s in a zero state, or a one state. In contrast a quantum bit is a much richer object that can exist in a quantum superposition of zero and one.

Dec 2, 2016 · The phase of these drives can be used to generate zero-duration arbitrary "virtual" Z-gates which, combined with two $X_{\pi/2}$ gates, can generate any SU(2) gate. Here we show how to best utilize these virtual Z-gates to both improve algorithms and correct pulse errors.

Aug 31, 2017 · Here we show how to best utilize these virtual Z-gates to both improve algorithms and correct pulse errors. We perform randomized benchmarking using a Clifford set of Hadamard and Z-gates and show that the error per Clifford is reduced versus a set consisting of standard finite-duration X and Y gates.

The Pauli-Z gate is a single-qubit rotation through π \pi π radians around the z-axis. Z = σ z = σ 3 = (1 0 0 − 1) \ Z = \sigma_z = \sigma_3 = \begin{pmatrix} 1 & 0 \\ 0 & -1 \end{pmatrix} Z = σ z = σ 3 = (1 0 0 − 1 ) Examples:
