Core SDK Examples

These examples use the Quantum Rings Core SDK APIs (QuantumRingsLib), including:

• Building circuits with QuantumCircuit

• Acquiring a backend with QuantumRingsProvider

• Executing with backend.run(...) and inspecting results

If you are migrating existing Qiskit code to run on Quantum Rings backends, see Qiskit Toolkit Examples instead.

Prerequisites

• Install the SDK (Install (CPU-only) or Install (GPU-enabled))

• Configure credentials (Quantum Rings credentials)

If you want a 5-minute end-to-end run first, start here: Quick Start (5 Minutes)

Feature demos

These are focused, “starting points” that highlight one or more Core SDK capabilities.

• GHZ state — build and run a GHZ circuit and inspect measurement counts.

Algorithm templates

These examples are longer-form templates for foundational algorithms. Use them as starting points for customization.

• Bernstein-Vazirani Algorithm — Bernstein–Vazirani

• Simon’s Algorithm — Simon’s algorithm

• Grover’s Search Algorithm — Grover search

• Shor’s Algorithm — Shor’s algorithm

• Quantum Fourier Transform — Quantum Fourier transform (and related circuits)

Optimization and variational algorithms

These examples focus on optimization workflows and variational patterns.

• Optimization Problems — classical optimization background (conceptual)

• Quadratic Unconstrained Binary Optimization (QUBO) — QUBO / Ising mapping concepts and setup

• Quantum Approximation Optimization Algorithm (QAOA) — QAOA (general template)

• Solving the Max-Cut problem using QAOA — Max-Cut as a QAOA application

• Variational Quantum Eigensolver (VQE) — VQE (variational eigensolver)
