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

Paris, December 4, 2020

Atos introduces “Q-score”, the 1st universal quantum metrics, applicable to all programmable quantum processors. Atos’ Q-score actions a quantum system’s effectiveness at dealing with real-existence troubles, those people which simply cannot be solved by conventional pcs, instead than basically measuring its theoretical performance. Q-score reaffirms Atos’ motivation to supply early and concrete rewards of quantum computing. About the previous 5 several years, Atos has come to be a pioneer in quantum apps via its participation in industrial and academic partnerships and funded initiatives, working hand-in-hand with industrials to produce use-cases which will be in a position to be accelerated by quantum computing.

Confronted with the emergence of a myriad of processor technologies and programming strategies, corporations seeking to spend in quantum computing need to have a trusted metrics to enable them pick out the most economical route for them. Remaining components-agnostic, Q-score is an aim, simple and fair metrics which they can count on,” explained Elie Girard, Atos CEO. “Since the start of ‘Atos Quantum’ in 2016, the 1st quantum computing field method in Europe, our intention has remained the same: progress the growth of field and analysis apps, and pave the way to quantum superiority.”

What does Q-score measure?

Right now the number of qubits (quantum models) is the most widespread figure of benefit for examining the performance of a quantum program. Nonetheless, qubits are volatile and vastly fluctuate in top quality (speed, security, connectivity, and so forth.) from 1 quantum technological know-how to yet another (these as supraconducting, trapped ions, silicon and photonics), generating it an imperfect benchmark device. By focusing on the potential to clear up nicely-identified combinatorial optimization troubles, Atos Q-score will supply analysis centers, universities, corporations and technological leaders with explicit, trusted, aim and similar outcomes when fixing real-earth optimization troubles.

Q-score actions the true performance of quantum processors when fixing an optimization difficulty, consultant of the close to-expression quantum computing period (NISQ – Noisy Intermediate Scale Quantum). To supply a body of reference for comparing performance scores and retain uniformity, Q-score depends on a typical combinatorial optimization difficulty, the same for all assessments (the Max-Slice Difficulty, identical to the nicely-identified TSP – Travelling Salesman Difficulty, see below). The score is calculated based mostly on the optimum number of variables in just these a difficulty that a quantum technological know-how can enhance (ex: 23 variables = 23 Q-score or Qs).

Atos will arrange the publication of a annually checklist of the most potent quantum processors in the earth based mostly on Q-score. Because of in 2021, the 1st report will involve true self-assessments provided by manufacturers.

Based on an open up accessibility program offer, Q-score is crafted on three pillars:

  • Application pushed: Q-score is the only metrics program based mostly on close to-expression obtainable quantum algorithms and actions a quantum system’s capacity to clear up functional operational troubles
  • Openness and relieve of use: Universal and free of charge, Q-score rewards from Atos’ technological know-how-neutral technique. Its program offer, such as tools and methodology, does not require major computation electric power to estimate the metrics
  • Objectiveness and trustworthiness: Atos brings together a components-agnostic, technological know-how-agnostic technique with a potent skills in algorithm layout and optimization acquired working with major field shoppers and technological know-how leaders in the quantum field​. The methodology used to create Q-score will be made general public and open up to evaluation.

A free of charge program package, which enables Q-score to be run on any processor will be obtainable in Q1 2021. Atos invitations all manufacturers to run Q-score on their technological know-how and publish their outcomes.

Many thanks to the superior qubit simulation abilities of the Atos Quantum Learning Device (Atos QLM), its potent quantum simulator, Atos is in a position to estimate Q-score estimates for different platforms. These estimates consider into account the traits publicly provided by the manufacturers. Success vary about a Q-score of fifteen Qs, but progress is quick, with an approximated regular Q-score courting from 1 yr back in the space of ten Qs, and an approximated projected regular Q-score courting 1 yr from now to be earlier mentioned twenty Qs.

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