Quantum Machine Learning (QML) frameworks, like AutoQML and quantum k-means, demonstrate the potential of cloud-based quantum computing in various domains. Quantum chemistry simulations, such as molecular hydrogen and beryllium hydride, showcase the advantages of quantum cloud computing in computational chemistry. Other applications include quantum cryptography, homomorphic encryption, and secure healthcare data processing. Quantum Cloud Providers and Platforms: Leading quantum hardware vendors, including IBM, IonQ, and Rigetti, offer cloud-based access to their quantum computers. Cloud providers like Amazon Braket and Microsoft Azure Quantum collaborate with third-party quantum hardware vendors to offer quantum computing services. These platforms provide access to a variety of quantum technologies, including superconducting, trapped ions, neutral atoms, and quantum annealing. Quantum Cloud Resource Management: Challenges in quantum cloud resource management, such as job scheduling, load balancing, and fault tolerance, require novel approaches. Distributed quantum computing techniques, like quantum serverless and quantum microservices, aim to address these challenges. Quantum Cloud Security and Privacy: Securing quantum cloud environments and protecting user data are critical concerns, requiring the development of quantum-safe cryptography and privacy-preserving techniques. Blockchain-based architectures and quantum homomorphic encryption are explored to enhance security and privacy in quantum cloud computing. The paper concludes by discussing the open problems and future research directions in quantum cloud computing, highlighting the potential opportunities and ongoing efforts to fully realize the benefits of this emerging paradigm.

Stats

Quantum cloud computing can solve certain problems, such as optimization, financial modeling, molecule simulation, and machine learning, much faster than classical computers. Quantum cloud providers offer access to quantum simulators with up to 5,000 qubits to support numerical studies, noise/error modeling, and parallel quantum device emulation. The number of qubits is not the only metric for benchmarking quantum computer performance; other factors include qubit quality, error rate, and connectivity.
