Quandela Announces Quandela Cloud 2.0 for Developing Quantum Photonics Applications

Insider’s memory

  • Quandela has announced the release of its new version of its quantum computing cloud service, Quandela Cloud 2.0.
  • The service provides access to the most advanced quantum servers available from Quellela.
  • It includes easy-to-use software for generating and manipulating quantum circuits, as well as middleware for running hybrid quantum-classical workflows.

PRESS RELEASE — Quandela, the European quantum computing provider, announces the release of its new version of its quantum computing cloud service, Quandela Cloud 2.0, offering end users the most powerful platform for developing quantum applications photonics.

Originally launched in January 2023 and now with hundreds of enterprise users, Quandela Cloud is a comprehensive platform for discovering, learning, testing and developing quantum solutions. It provides access to the most advanced quantum servers available from Quandela, easy-to-use software for generating and manipulating quantum circuits, and middleware for running hybrid quantum-classical workflows in heterogeneous computing environments.

For quantum developers, researchers and engineers, this announcement has multiple advantages:

  • Quandela Cloud 2.0 offers significant improvements in circuit construction, compilation time and memory consumption compared to the previous version.
  • Perceval, the open source framework for programming photonic quantum computers, provides developers with versatile and powerful user tools for mapping circuits onto quantum hardware and running them on simulators or real QPUs.
  • The introduction of new application-centric SDKs and APIs aims to facilitate seamless integration into cloud system data flow and hybrid computing with conventional processors (CPU and GPU) in data center infrastructures.

This release follows the successful launch of two quantum computing systems with cloud providers in Europe and North America. As Quandela continues its journey, it remains dedicated to on-time deliveries and continued technical advancements.

Discover the main improvements of this new version:

Quantum toolbox

This comprehensive suite includes pre-optimized primitives tailored to specific applications such as Variational Quantum Eigensolver (VQE) and graphical analysis. It accelerates the production of quantum algorithms for industry-specific use cases, by providing native optimization of these algorithms with Quandela QPUs and select GPUs. Supported by the expertise of the Quandela application team, users will receive direct assistance to maximize the usefulness and effectiveness of these tools.

Exqalibur – GPU-enhanced emulation

Introducing a new emulator for photonic qubits that leverages the capabilities of the most powerful GPU and enables calculations on an unprecedented scale. With this advancement, users can now explore up to 150 billion parameter spaces across 20 photonic qubits at kilohertz frequencies, facilitating faster prototyping and optimization of quantum algorithms.

Exclusive QPU reservation service

In addition to standard on-demand access, the new system offers premium users an intuitive booking platform to secure QPU time on designated dates and times. This tailored booking model improves user experience by facilitating seamless coordination between development teams.

QPU Progress – Altair Overview

With the release of Quandela Cloud 2.0, significant improvements have been made to quantum computing hardware. Altair, the latest 10-qubit quantum processor, takes center stage and is now available to developers around the world. This enhanced quantum processing unit builds on the success of its predecessor, Ascella, which launched in January 2023 and operated for more than 12,900 hours. Ascella achieved a remarkable availability rate of 92% over a 6-month operation.

Built-in error mitigations

Two powerful patented error mitigation techniques have been introduced for Altair control, allowing us to further increase the fidelity and speed of quantum gates:

  • AI-driven quantum fidelity enhancement: This technique leverages the power of machine learning’s “see-through box” methodology to significantly mitigate hardware imperfections. This innovative approach increases qubit fidelity by several percentage points, ensuring even higher reliability and performance in quantum computing applications. Further details are provided below.
  • Photon recycling: This unprecedented technique leverages lossy output photon states to consolidate the statistics of lossless states, enabling more accurate estimation of the probability distribution with fewer numbers of shots.

Combined with AI-enhanced error mitigation software and transpilation technique, Altair achieves fidelities of: 1-qubit gate: 99.94% and 2-qubit gate: 98.2% and a Q score of 6.
