Atos announces Q-score, the only universal metrics to assess quantum performance and superiority

Paris, December 4, 2020

Atos introduces “Q-score”, the initially common quantum metrics, applicable to all programmable quantum processors. Atos’ Q-score actions a quantum system’s effectiveness at handling serious-lifestyle difficulties, people which can’t be solved by standard personal computers, somewhat than only measuring its theoretical overall performance. Q-score reaffirms Atos’ motivation to provide early and concrete gains of quantum computing. Around the past five years, Atos has come to be a pioneer in quantum programs as a result of its participation in industrial and tutorial partnerships and funded tasks, operating hand-in-hand with industrials to establish use-cases which will be capable to be accelerated by quantum computing.

Confronted with the emergence of a myriad of processor technologies and programming techniques, corporations hunting to commit in quantum computing want a trusted metrics to assistance them pick the most effective route for them. Remaining components-agnostic, Q-score is an objective, easy and honest metrics which they can rely on,” said Elie Girard, Atos CEO. “Since the start of ‘Atos Quantum’ in 2016, the initially quantum computing sector application in Europe, our goal has remained the very same: progress the improvement of sector and study programs, and pave the way to quantum superiority.”

What does Q-score measure?

Currently the amount of qubits (quantum units) is the most popular determine of advantage for assessing the overall performance of a quantum technique. Having said that, qubits are risky and vastly vary in good quality (speed, security, connectivity, etc.) from one quantum engineering to a further (these kinds of as supraconducting, trapped ions, silicon and photonics), generating it an imperfect benchmark instrument. By concentrating on the ability to fix nicely-recognised combinatorial optimization difficulties, Atos Q-score will give study centers, universities, companies and technological leaders with specific, trusted, objective and equivalent outcomes when fixing serious-earth optimization difficulties.

Q-score actions the true overall performance of quantum processors when fixing an optimization challenge, representative of the close to-expression quantum computing period (NISQ – Noisy Intermediate Scale Quantum). To give a frame of reference for evaluating overall performance scores and sustain uniformity, Q-score relies on a regular combinatorial optimization challenge, the very same for all assessments (the Max-Cut Difficulty, related to the nicely-recognised TSP – Travelling Salesman Difficulty, see underneath). The score is calculated dependent on the maximum amount of variables in just these kinds of a challenge that a quantum engineering can optimize (ex: 23 variables = 23 Q-score or Qs).

Atos will arrange the publication of a yearly list of the most impressive quantum processors in the earth dependent on Q-score. Due in 2021, the initially report will involve true self-assessments offered by brands.

Dependent on an open up obtain program package deal, Q-score is constructed on three pillars:

  • Application pushed: Q-score is the only metrics technique dependent on close to-expression available quantum algorithms and actions a quantum system’s potential to fix useful operational difficulties
  • Openness and ease of use: Common and free of charge, Q-score gains from Atos’ engineering-neutral method. Its program package deal, including tools and methodology, does not need hefty computation electricity to determine the metrics
  • Objectiveness and dependability: Atos combines a components-agnostic, engineering-agnostic method with a powerful know-how in algorithm layout and optimization obtained operating with main sector clientele and engineering leaders in the quantum field​. The methodology used to construct Q-score will be created general public and open up to assessment.

A free of charge program kit, which permits Q-score to be operate on any processor will be available in Q1 2021. Atos invites all brands to operate Q-score on their engineering and publish their outcomes.

Many thanks to the advanced qubit simulation abilities of the Atos Quantum Discovering Device (Atos QLM), its impressive quantum simulator, Atos is capable to determine Q-score estimates for various platforms. These estimates acquire into account the properties publicly offered by the brands. Results assortment close to a Q-score of fifteen Qs, but progress is quick, with an estimated common Q-score relationship from one calendar year ago in the spot of 10 Qs, and an estimated projected common Q-score relationship one calendar year from now to be earlier mentioned 20 Qs.

Q-score has been reviewed by the Atos Quantum Advisory Board, a team of intercontinental gurus, mathematicians and physicists authorities in their fields, which fulfilled on
