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 …

Controlled-Z gate. This is a Clifford and symmetric gate. Can be applied to a QuantumCircuit with the cz() method. Circuit symbol:

Controlled Z (CZ) gate is one of controlled phase gates. See discussed in Section 7.3. 7.2.1. Definition. When gate CZ q 0 q 1 acts on | q 1 q 0 , Z is applied to q 1 if q 0 = 1 and nothing is …

Quamtum Gate - Controlled Z. The Controlled-Z (CZ) gate is a two-qubit gate used in quantum computing. It operates on a pair of qubits, with one qubit acting as the control and the other as …

May 27, 2021 · IBM Quantum Experience and other Algorithm Creators generally draw the CZ gates like this: Does it not matter which qubit is the control and which is the target? If so why?

The CZ gate (or CPhase gate) is two-qubit operation defined as: \ CZ = \begin {pmatrix} 1 & 0 & 0 & 0 \\ 0 & 1 & 0 & 0 \\ 0 & 0 & 1 & 0 \\ 0 & 0 & 0 & -1 \end {pmatrix} CZ = 1 0 0 0 0 1 0 0 0 0 1 0 …

Feb 29, 2024 · Harnessing the state-of-the-art fabrication techniques and a model-free pulse-optimization process based on reinforcement learning, we translate the theoretical DTC …

The matrix representation of a controlled Z gate applied to control qubit 1 and target qubit 2 is [ 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 − 1 ] . If the control qubit is in the | 0 〉 state, then this gate leaves …

Explore the quantum CZ gate and its function as a controlled Z gate. Learn how it phase-flips the second qubit of a multipart qubit.

Nov 21, 2024 · In this work, we report on a two-qubit gate that achieves that milestone and sustains it for 12 h. Superconducting qubits, with their ease of scalability and controllability, are …
