Quantum Software Development with QuantumPath®：Unleashing the Power of Quantum Computing

1. Introduction

Quantum theory is a revolutionary physics theory that describes the behavior of matter at sub - atomic levels. Quantum computers, based on principles like superposition and entanglement, aim to exponentially boost computational power. This has led to interesting developments in various fields such as cryptography, artificial intelligence, and communications.

However, developing quantum software currently faces numerous challenges. There is a wide variety of quantum programming languages, development environments, simulators, and hardware. Moreover, there is no established methodology for high - quality quantum software development.

QuantumPath® (QPath®) is a quantum software development platform designed to support the design, implementation, and execution of quantum software applications.

2. QPath® Principles and Functionalities

QPath® is built on several key principles:
- Agnosticism : Supports both quantum gate - based and annealing technology.
- Extensibility : Can adapt to the continuous research and evolution of quantum technologies through a well - designed extension model.
- Integration : Enables the integration of quantum/classical (hybrid) information systems.
- Independency : Follows the “write once, run everywhere” principle, masking the complexities of different environments.
- Optimization : Collects and analyzes stored telemetry.
- Scalability : Can be deployed on multiple servers to accommodate user and process growth.
- Security : Provides secure access to service layers and protects system assets.
- Software engineering : Supports the quantum software life cycle and its engineering.
- Usability : Helps visually design quantum assets, define requirements, and explore results without worrying about quantum computer languages.

QPath® is composed of two large functional units:
- CORE Modules : The core of the QuantumPath platform, which can manage solutions independent of quantum technology with the help of general - purpose tools.
- The APPs platform : Integrates with the CORE modules and simplifies the management of hybrid software project life cycles for development teams.

2.1 Management of Solutions and Their Assets

QPath® includes all the necessary elements for a “quantum application,” such as the application solution and its relationship to the quantum execution context, quantum circuits, direct code units, intermediate language treatment of assets, and main flows for algorithm coordination and execution control. All data in the cloud system is encrypted from origin to storage.

2.2 Tools for the Design of Quantum Assets

• Circuit Editor : Allows the graphical design of quantum gate circuits through a web UI based on the Quirk Quantum Circuit Simulator. It supports drag - and - drop and generates an intermediate QpIL language for running algorithms on any quantum gate hardware.
• Annealer Compositor : A high - level tool for graphically modeling optimization problems. The design is simplified to four elements:
  • Parameters : Variables with constant values for parameterizing problem properties.
  • Auxiliary data : Arrays of data used in problem rules.
  • Classes : Define different types of real variables in the problem.
  • Rules : Model the objective function and constraints of the problem.
    After editing, it compiles the circuit and generates code in annealing meta - language.
• Flow Editor : Coordinates the execution of circuits and other elements in an application.
• Direct Code Editor : Allows users to create code for specific hardware. It simplifies the process by letting users write code inside a module abstraction and provides managed items for integration into the QPath® pipeline. The defined code can be encapsulated as a standard circuit.

2.3 Connection Points and qSOA

QPath® enables the interconnection of quantum applications in a classic solution ecosystem. It provides a REST API service layer, allowing classic applications to easily consume quantum algorithms stored in the system or create new ones using QPath® IL. For example, the following Connection Point checks the completion status and outcome of a job token:

(/api/connectionPoint/GetQuantumExecutionResponse/jobtoken/idSolution/idFlow)
HTTP GET HEADERS
content - type: application/json
Authorization: Bearer tokenJWT
RESPONSE
{
    "ExitCode": "OK",
    "ExitMessage": null,
    "ExecutionData": {
        "Solution": "WEBINARAnneal",
        "Flow": "BoxFlows",
        "Device": "dwave_ExactSolver_simulator",
        "Histogram": "histogram struct ",
        "Duration": 157226789
    }
}

QPath® supports the qSOA (Quantum Service Oriented Architecture) based on connection points, which simplifies the integration of quantum services into classical systems.

2.4 Enterprise Backend

The backend is responsible for the overall operation of the platform. It is designed with security, high availability, load balancing, and asynchronous customer processing in mind. It manages connections to quantum simulators and computers, collects telemetry, and provides knowledge and automatic assistance. QPath® allows users to work with various quantum technologies from different providers and third - party simulators.

3. QPath® Advantages

QPath® offers several advantages:
- Facilitates Quantum Workforce Development : The shortage of specialized workforce is a major obstacle in the quantum computing industry. QPath® simplifies the development of quantum software, enabling engineers and programmers without “universal” skills to work on quantum projects. It supports multidisciplinary teams and focuses on the functional knowledge required for quantum solutions in different fields. Additionally, QPath® developers have access to aQuantum Knowledge, a portal with useful resources.
- Solves the Quality Problems of Quantum Computing Platforms :
| Quality Problem | How QPath® Solves It |
| — | — |
| Lower level of programming abstractions | QPath® is agnostic about quantum programming languages and supports visual designers and the Annealer Compositor. |
| Platform heterogeneity | Provides tools for development teams to focus on solutions without worrying about platform specificities. |
| Remote software development and deployment | Offers a complete set of tools for asset design, construction, testing, and execution. |
| Dependency on known quantum algorithms | Supports the creation, testing, implementation, and reuse of quantum algorithms, and has extensibility for new connectors. |
| Limited portability of software | Allows automatic lifecycle management from model to results, following the “write once, run everywhere” principle. |
| Lack of native quantum operating system | The enterprise backend is designed with security, high availability, load balancing, and asynchronous processing. |
| Fundamentally different programming model | Supports the integration of hybrid software and simplifies the management of hybrid project life cycles. |

4. Example of Quantum Development with QPath®

Let’s take the example of adding a simple QRNG (Quantum Random Number Generator) into a Navision data form using a pre - configured quantum provider in the NAV environment.
The steps are as follows:
1. Define the solution and assets in QPath® .
2. Define the QNRG using the circuit editor .
3. Compose the corresponding flow .
4. Execute the QNRG and select different quantum machines to explore the results .
5. Extend Navision using the qSOA REST API .
6. Use the Navision QPath Setup Dialog (custom NAV extensions developed) .
7. Validate and seal customer data with hash using the QRNG numbers obtained. Generate a hash for validated and sealed customers using a developed protocol .

In this example, all executions are recorded with telemetry, and the results are applied to the NAV data. If the QRNG improves over time, Navision can execute the call more accurately without code modification.

The following mermaid flowchart shows the process:

This example demonstrates how QPath® can be used in a practical scenario to integrate quantum computing into existing software systems.
