L'informatique quantique est une technologie émergente et potentiellement une rupture technologique pour nos domaines scientifiques. À l'IN2P3, vous possédez une expertise dans ce domaine. La question est, devrions-nous coordonner nos activités? Quel serait le bon niveau d'engagement? Dans une première discussion, nous voulons parler de ces points.
CR Quantum Computing @IN2P3

Introduction (V. Beckmann, IN2P3):
• Technologie à fort potentiel pour nos sciences
• Matériel pas encore au niveau pour être utlisé par nos sciences
• Difficile à prévoir quand du matériel plus mature sera disponible
• Explorez ce que ces nouvelles technologies pourraient apporter à notre domaine
QC for many-body systems at the nucleonic scale or below (D. Lacroix, IPNO):
• QC is not a new subject
• Simple problems easily described in a CC can be very difficult on a QC
• QC can lead to major breakthroughs in complex problems
• US: quantum computing for nuclear physics started group 2017, with significant investment over 5 years of 20 postdocs and 30 PhD grants, addressing many fields
• QC is very challenging and exciting
• intellectually satisfactory
• might lead to major breakthrough in different IN2P3 fields
• natural synergies between private and public sector
• emerging strong collaborations
• rapid actions needed if IN2P3 wants to be competitive
• risk that finally QC will not fulfill the promises
Résumé atelier Quantum Computing @ CERN, November 2018 (B. Vulpescu, LPC)
• https://indico.cern.ch/event/719844/
• organized by OpenLab (CERN)
• 400 representatives of the HEP community present at workshop
• quantum technologies as a key topic for the future of particle physics, 2nd quantum revolution
• quantum co-processor: augmenting, not replacing traditional HPC systems
• Different levels need to be developed: quantum chip, control electronics, compilers/runtimes, application algorithms.
• various companies in the field: DWave, Microsoft, rigetti, IBM, Google
• training and tutorials for HEP, co-developed and delivered together with Google
Discussion:
• QC with >1000 qbits (as e.g. offered by DWave) are not “real” QC but very noisy, thus solving QC problems statistically
• these “fake” QC seem to be popular in the private sector and are seen as a great opportunity
• to be competitive, significant investment (especially RH!) would be necessary
• IN2P3 cannot contribute to building QC hardware, but can add to solving fundamental physics problems in the context of QC.
• first step to enter QC field is certainly self formation: read about QC, qubits, etc. and try out some of the open source software available
• two main motivations within IN2P3 to deal with quantum computing: concrete use cases and academic interest
• interest in diffierent topics: hardware development, software development and interfacing, and as user of both existing QC or software
• a common workshop (with hands-on possibilities) would help to coordinate and inform the interested colleagues
•
Next steps
Denis Lacroix (IPNO) to coordinate the interest group
Investigate training opportunities and collaborations with
• CERN OpenLab (Federico Carminati),
• CEA (Philippe Chomaz)
• INRIA (Anthony Leverrier)
• INS2I
• Private sector, e.g. DWave
• Paris Centre for Quantum Computing (PCQC): http://www.pcqc.fr/
Evaluate relevance / opportunities of the European Quantum Flagship initiative
Discuss possibility to organize IN2P3 workshop (preferentially before Christmas)
