Get ready for the Quantum revolution

The quantum shift is coming, it will enable to solve some complex problems faster than the current most powerful HPC systems

As a computing leader in Europe, Atos launched in 2016 the quantum program led by a high level advisory board and implemented by the Atos Quantum lab.

What’s New?

Atos and OVHcloud partner to accelerate development of quantum computing

Atos and OVHcloud, the European leader in cloud computing, announce a partnership in the field of quantum computing to make Atos’ quantum emulator available “as a service” through OVHcloud offers. This European premiere will make quantum emulations technologies more accessible, thereby expanding the quantum technologies ecosystem.

Atos announces its first reseller agreement in Quantum computing in the US with Aspen Systems Inc.

Aspen Systems Inc. will resell the most powerful Quantum emulator on the market. Atos developed QLM (Quantum Learning Machine) since 2016. This appliance emulates up to 41 Qubits hardware, incorporate noise simulation, generate circuit for all existing Quantum Computer, and optimize those circuits in function of the targeted hardware.

The Atos Quantum Learning Machine added value explained

With this statement in mind, Atos has created the Quantum Learning Machine, a complete on-premise environment designed to prepare today the Quantum revolution of tomorrow…

The Atos Quantum Learning Machine approach

  • Help people learn and experiment with quantum computers
  • Develop applications and algorithms
  • Without the need to wait for quantum machines to be physically available

Inside the Quantum Learning Machine

The Atos Quantum Learning Machine is a complete appliance

  • Offering an universal programming environment to avoid the vendor lock-in
  • Simulating up to 41 qubits, on a simple business server physical dimensions
  • Gathering universal quantum programming language (AQASM, Atos Quantum Assembly Language, quantum hybrid language based on Python)
  • Allowing programmers to develop their own algorithms on any existing or future quantum programming framework

QLM for Combinatorial Optimization

First revealed in June 2020 and officially showcased at SC20, Atos’ QLM for Combinatorial Optimization environment will allow users to prepare codes to tackle combinatorial optimization problems using either quantum annealing or gate-based quantum computing.

As an additional feature of the Atos Quantum Learning Machine (QLM), Atos then allows users to simulate their code either on noisy or noiseless digital quantum simulators or using quantum-inspired modules like Simulated Quantum Annealing (SQA) or Simulated Bifurcation Algorithm (SBA).

Quantum Computing promises to solve larger optimization problems faster and more accurately, which will generate tangible benefits for industries, such as portfolio management, logistics, antenna location, chip design or clinical trial database search.

Key benefits of using both approaches in the Atos QLM

Better understand the specificities of quantum annealing and digital quantum computing

Compare the benefits and constraints of two quantum computing technological paths applied to combinatorial optimization problems

Prepare code to then run on NISQ accelerators or Quantum Annealing machines using the same programming environment

Atos QLM E

Atos Quantum Learning Machine EnhancedAtos QLM E – is a new range of GPU-accelerated Atos Quantum Learning Machine. Atos QLM E offers an acceleration up to 12 times to simulate variational algorithms that a particularly well-suited for NISQ (Noisy Intermediate Scale Quantum) devices, which will be the first quantum accelerators to be commercialized in the next few years.


By promising to apply, in the near-term, computation capabilities that are beyond the reach of even the most powerful existing computers to solve complex, real-life problems, NISQ devices will play an important role in determining the commercial potential of quantum computing. Herein lies a double challenge for the industry: developing NISQ algorithms is as important as building the machines, since both are required to identify concrete applications. Atos QLM E has been optimized to drastically reduce the compilation time of hybrid quantum-classical algorithms simulations, leading to quicker advancement in application research.

Atos QLM E[nhanced] accelerating research in the NISQ era

  • Accelerate your quantum simulations up to 12x
  • Optimized for variational algorithms best suited for the NISQ* era (up to 30 qubits)
  • Upgrade your QLM to a QLM E very easily to benefit from these enhanced features

Accelerate research on variational algorithms using Atos QLM E:

Quantum Approximate Optimization Algorithm

Variational Quantum Eigensolver / Variational Imaginary Time Evolution

Atos cybersecurity Data Protection Governance

Variational Quantum Factoring

Variational Quantum Classifier
