It accelerates development with optimized application subroutines, cutting‑edge noise mitigation, performance analytics tools, and a collaborative workspace. ### Product Capabilities Work in a collaborative JupyterLab setup simplifying development. Track experiments, job histories, and circuit metrics. Quickly iterate development with insights into algorithms, middleware, and circuit performance Develop and deploy applications on different quantum processors.. Employ middleware that reduces noise, optimizes circuits, and improves reliability on noisy Quantum Processing Units (QPUs). Take advantage of utility routines optimized for performance at large scales, including efficient data loading and QML warm-starting. ### Quick Start To create your quantum application with Haiqu, follow [simple end-to-end workflow example](quickstart) or choose the guide that matches your needs: Quantum circuit analysis is important for understanding the structure, complexity, and feasibility of executing a circuit on quantum hardware or simulators. It helps to identify key properties such as gate composition, depth, connectivity, and noise susceptibility, which impact performance and accuracy. In this example, you'll learn how to execute quantum circuits using the Haiqu SDK on a variety of backends — from ideal simulators to real quantum hardware (e.g. via IBM Quantum). We will cover different scenarios and walk you through the steps required to execute the circuits on a quantum device or simulator. A key challenge in quantum computing applications — such as quantum machine learning, finance, and optimization — is efficiently encoding classical data into quantum states. This process, dubbed as Quantum Data Loading, involves preparing quantum circuits that convert classical information into a suitable quantum representation. Effective data loading is critical for running practical quantum algorithms beyond synthetic benchmarks. In this example, we'll follow the Qiskit Finance tutorial on Pricing European Call Options. We recommend reviewing that tutorial to better understand the problem and its quantum solution. ### Learn More Lean more about Haiqu. Lean the key quantum computing terms. Join the Haiqu team.
