Top 10 Quantum Cloud Computing Companies of 2023

Quantum computing is a new technology that can solve problems much faster than normal computers. Companies are now providing access to quantum computers through cloud computing services. These “quantum cloud computing” platforms allow more organizations to use quantum computers remotely. In this article, we rank the top 10 quantum cloud computing companies.

What is Quantum Cloud Computing?

Quantum cloud computing means accessing quantum computers over the internet cloud. It allows users to develop and run quantum algorithms without needing to build the actual quantum hardware. Quantum cloud providers offer services like:

  • Virtual access to real quantum processors
  • Development tools and APIs for building quantum programs
  • Quantum simulators for testing algorithms
  • Hybrid quantum-classical computing capabilities
  • Quantum security services

By providing these services remotely through the cloud, quantum power can be democratized beyond labs working on quantum hardware

Here are Top 10 Companies of 2023 providing these services

1. IBM Quantum

IBM was an early pioneer in quantum computing and made its quantum systems available through the cloud. The IBM Quantum platform includes the Quantum Composer for assembling quantum programs and the Qiskit open-source SDK. Over 200,000 users have run hundreds of billions of executions on IBM’s quantum systems.

2. Amazon Braket

Amazon Web Services launched Braket in 2019 as a fully managed quantum computing service. Users can get started quickly by choosing from quantum hardware providers like D-Wave, IonQ, and Rigetti. Braket provides a development environment to build quantum algorithms and test them in simulation before running on actual quantum processors.

3. Azure Quantum

Microsoft entered the quantum space by offering quantum computing access through Azure. Azure Quantum provides a managed environment for developing and running quantum programs on various hardware backends. It also integrates with other Azure services for building hybrid quantum-classical solutions.

4. D-Wave Leap

D-Wave Systems is focused on building quantum annealing computers. The Leap cloud service provides real-time access to D-Wave quantum processors with minimal setup. Users can submit problems and get results back through an intuitive interface and Python SDK. Over 200 early applications have been built on Leap.

5. Rigetti Quantum Cloud Services

Rigetti Computing offers both quantum hardware and software. The Rigetti Quantum Cloud Services platform enables coding, testing, and running quantum algorithms on Rigetti’s quantum processors. Users can access Rigetti’s quantum machines and simulators through forest SDK tools.

6. IonQ Quantum Cloud Service

IonQ makes trapped ion quantum computers available through cloud APIs and SDKs. Developers can build and test quantum circuits with the IonQ API before executing them on IonQ hardware. Benchmarking shows that IonQ quantum computers outperform classical computers on certain workloads.

7. Xanadu Quantum Cloud

Xanadu offers photonic quantum computing via the cloud. Users can access Xanadu’s quantum photonic hardware and simulators remotely to run quantum machine learning and optimization algorithms. The Xanadu Quantum Cloud integrates with PennyLane for quantum programming.

8. Pasqal Quantum Cloud Platform

Pasqal provides neutral atom quantum processors accessible over the cloud. Users can connect to Pasqal quantum processors through Python and REST APIs to run quantum algorithms. The Pasqal Quantum Cloud Platform also includes simulators and development tools.

9. Quantinuum H1 Cloud

Quantinuum (formerly Cambridge Quantum) makes its H1 quantum computing system available through the cloud. Developers can use Python SDKs like TKET and PyCQ to build quantum programs and run them on H1 hardware with error correction. Quantinuum also provides cybersecurity keys generated on quantum devices.

10. Zapata Quantum Computing

Zapata Computing focuses on quantum algorithms and software. The Orquestra Platform enables developers to access Zapata’s quantum-classical frameworks through a web interface or Python SDKs. Users can run algorithms for chemistry, machine learning, optimization, and more on various quantum backends.

Each company on this list offers cloud-based access to real quantum computers and/or simulators. Key players include Amazon, Microsoft, IBM, Google, D-Wave, Rigetti, and IonQ. We expect more companies to move into the quantum cloud space as the technology matures.


Quantum cloud computing opens up powerful capabilities in simulation, optimization, and machine learning. Leading technology companies like Amazon, Microsoft, IBM, and Google provide on-demand access to real quantum computers over the internet. We expect more organizations to adopt quantum cloud services as practical applications emerge across industries like finance, pharmaceuticals, energy, and logistics. The growth of quantum cloud computing platforms will accelerate innovation in the quantum space.
