Quantum Gates
Last Updated: April 2, 2025What are Quantum Gates? In quantum computing, quantum gates are the fundamental operations that manipulate the state of qubits. They are analogous to classical logic gates (like AND, OR, NOT) in classical computing. However, they have unique properties that enable quantum computers to perform certain tasks more efficiently than classical computers. Key Properties of Quantum...
Measurement on Basis(x,y,z)
Last Updated: April 7, 2025In quantum computing, operations on qubits are performed using quantum gates, which are mathematically represented by unitary matrices. A key characteristic of these gate matrices is that they preserve the total probability of quantum states. This is guaranteed by their unitarity: when a gate’s matrix is multiplied by its conjugate transpose, the result is the...
Circuit Composer Area
Last Updated: April 7, 2025Here in this section, you can build your quantum circuit by dragging gates onto the horizontal qubit “wires” that make up your quantum register. If you need to edit parameters of the gate and its settings, just select the gate on the horizontal qubit wire and click the Edit icon. Here is a brief video...
Code Editor Area
Last Updated: April 7, 2025“As a unified platform, you can build your circuit or code once and execute it across multiple quantum frameworks such as Qiskit, CirQ, and CudaQ. To support this, the platform offers three different language formats, making it easy to create quantum circuits and generate code in a variety of quantum programming languages. Any changes made...

Running Circuits
Last Updated: April 2, 2025Running Quantum Circuits: A Guide 1. Platform Selection CPU (Simulators): Simulators: Ideal for initial circuit design, testing, and debugging. They offer high fidelity and can simulate small- to medium-sized circuits efficiently. Advantages: Fast execution, low cost, easily accessible. Disadvantages: Limited to smaller circuits due to exponential resource growth with increasing qubit number....
Visualization
Last Updated: April 2, 2025The visualizations are shown in the window at the bottom of the Qniverse workspace. You can choose from a combination of histograms, state vectors, or probability distributions at the bottom of the workspace. Visualizations: Visualizations characterize your circuit as you build it. They use a single-shot state vector simulator, which is different from the system...
