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

Paris, December four, 2020

Atos introduces “Q-score”, the to start with universal quantum metrics, applicable to all programmable quantum processors. Atos’ Q-score actions a quantum system’s performance at handling actual-daily life complications, those people which can’t be solved by conventional computers, relatively than simply measuring its theoretical functionality. Q-score reaffirms Atos’ motivation to supply early and concrete positive aspects of quantum computing. Over the past five years, Atos has become a pioneer in quantum applications by way of its participation in industrial and tutorial partnerships and funded jobs, performing hand-in-hand with industrials to create use-instances which will be able to be accelerated by quantum computing.

Faced with the emergence of a myriad of processor systems and programming ways, corporations hunting to invest in quantum computing require a trusted metrics to help them select the most successful path for them. Staying hardware-agnostic, Q-score is an objective, easy and honest metrics which they can rely on,” reported Elie Girard, Atos CEO. “Since the start of ‘Atos Quantum’ in 2016, the to start with quantum computing sector system in Europe, our intention has remained the exact same: advance the growth of sector and investigation applications, and pave the way to quantum superiority.”

What does Q-score measure?

These days the quantity of qubits (quantum units) is the most typical figure of merit for assessing the functionality of a quantum technique. However, qubits are volatile and vastly fluctuate in top quality (speed, balance, connectivity, and many others.) from 1 quantum technologies to yet another (these kinds of as supraconducting, trapped ions, silicon and photonics), earning it an imperfect benchmark device. By concentrating on the ability to solve very well-recognised combinatorial optimization complications, Atos Q-score will give investigation facilities, universities, companies and technological leaders with express, trusted, objective and comparable benefits when resolving actual-planet optimization complications.

Q-score actions the precise functionality of quantum processors when resolving an optimization dilemma, representative of the in close proximity to-term quantum computing period (NISQ – Noisy Intermediate Scale Quantum). To give a frame of reference for comparing functionality scores and manage uniformity, Q-score depends on a regular combinatorial optimization dilemma, the exact same for all assessments (the Max-Cut Difficulty, identical to the very well-recognised TSP – Travelling Salesman Difficulty, see underneath). The score is calculated centered on the highest quantity of variables within these kinds of a dilemma that a quantum technologies can optimize (ex: 23 variables = 23 Q-score or Qs).

Atos will organize the publication of a yearly listing of the most potent quantum processors in the planet centered on Q-score. Owing in 2021, the to start with report will involve precise self-assessments provided by brands.

Based on an open up access computer software package, Q-score is created on 3 pillars:

  • Software driven: Q-score is the only metrics technique centered on in close proximity to-term out there quantum algorithms and actions a quantum system’s capability to solve simple operational complications
  • Openness and relieve of use: Universal and free, Q-score positive aspects from Atos’ technologies-neutral approach. Its computer software package, which includes tools and methodology, does not have to have hefty computation electric power to calculate the metrics
  • Objectiveness and reliability: Atos combines a hardware-agnostic, technologies-agnostic approach with a strong experience in algorithm style and optimization acquired performing with main sector purchasers and technologies leaders in the quantum field​. The methodology used to construct Q-score will be created general public and open up to evaluation.

A free computer software kit, which allows Q-score to be operate on any processor will be out there in Q1 2021. Atos invites all brands to operate Q-score on their technologies and publish their benefits.

Many thanks to the highly developed qubit simulation capabilities of the Atos Quantum Discovering Device (Atos QLM), its potent quantum simulator, Atos is able to calculate Q-score estimates for several platforms. These estimates take into account the qualities publicly provided by the brands. Success array all-around a Q-score of 15 Qs, but progress is rapid, with an approximated typical Q-score relationship from 1 12 months in the past in the place of 10 Qs, and an approximated projected typical Q-score relationship 1 12 months from now to be earlier mentioned twenty Qs.

Q-score has been reviewed by the Atos Quantum Advisory Board, a group of worldwide professionals, mathematicians and physicists authorities in their fields, which satisfied on
