  DARPA: Taking the Next Step in Quantum Information Processing

  Universal quantum computers with millions of quantum bits, or qubits – which can represent a one, a zero, or a coherent linear combination of one and zero – would revolutionize information processing for commercial and military applications. Realizing that vision, however, is still decades away. The problem is the performance and reliability of quantum devices depend on the length of time the underlying quantum states can remain coherent. If you wait long enough, interactions with the environment will make the state behave like a conventional classical system, removing any quantum advantage. Often, this coherence time is significantly short, which makes it difficult to perform any meaningful computations. To exploit quantum information processing before fully fault-tolerant quantum computers exist, DARPA today announced its Optimization with Noisy Intermediate-Scale Quantum devices (ONISQ) program. This effort will pursue a hybrid concept that combines intermediate-sized quantum devices with classical systems to solve a particularly challenging set of problems known as combinatorial optimization. ONISQ seeks to demonstrate the quantitative advantage of quantum information processing by leapfrogging the performance of classical-only systems in solving optimization challenges. A Proposers Day for interested proposers is scheduled for March 19, 2019, at the Executive Conference Center in Arlington, Virginia: https://go.usa.gov/xEp8M “A number of current quantum devices with more than 50 qubits exist, and devices with greater than 100 qubits are anticipated soon,” said Tatjana Curcic, program manager in DARPA's Defense Sciences Office. “Qubits' short lifetime and noise in the system limit how many operations you can do efficiently, but a new quantum optimization algorithm has opened the door for a hybrid quantum/classical approach that could outperform classical systems.” Solving combinatorial optimization problems – with their mindboggling number of potential combinations – is of significant interest to the military. One potential application is enhancing the military's complex worldwide logistics system, which includes scheduling, routing, and supply chain management in austere locations that lack the infrastructure on which commercial logistics companies depend. ONISQ solutions could also impact machine-learning, coding theory, electronic fabrication, and protein-folding. ONISQ researchers will be tasked with developing quantum systems that are scalable to hundreds or thousands of qubits with longer coherence times and improved noise control. Researchers will also be required to efficiently implement a quantum optimization algorithm on noisy intermediate-scale quantum devices, optimizing allocation of quantum and classical resources. Benchmarking will also be part of the program, with researchers making a quantitative comparison of classical and quantum approaches. In addition, the program will identify classes of problems in combinatorial optimization where quantum information processing is likely to have the biggest impact. “If we're successful, the outcome of ONISQ will be the first demonstration of a quantum speedup compared to the best classical method for a useful problem,” Curcic said. ONISQ seeks multidisciplinary teams with expertise in experimental and theoretical physics, computer science and applied mathematics among others. DARPA plans to release a Broad Agency Announcement (BAA) solicitation in several weeks at: http://go.usa.gov/Dom. https://www.darpa.mil/news-events/2019-02-27

  Boeing dévoile son avion sans pilote

  Louis Neveu Lors du salon aéronautique Avalon 2019 en Australie, Boeing a dévoilé la maquette d'un futur drone militaire omnirôle. Doué d'intelligence artificielle, ce Boeing Airpower Teaming System pourrait épauler un véritable avion de chasse. Actuellement en Australie, près de Melbourne, se tient le salon professionnel aéronautique international Avalon 2019. C'est sur cet équivalent du salon du Bourget destiné à la zone Asie-Pacifique que Boeing vient de dévoiler son projet Airpower Teaming System. Il s'agit d'un drone à vocation militaire doté d'intelligence artificielle. Sur le stand de Boeing, une maquette de cet appareil, dont le concept sera baptisé Loyal Wingman, dévoilait des lignes conçues pour atténuer la signature radar de l'appareil. Cet avion sans pilote de 11,7 mètres de longueur disposera d'un rayon d'action d'environ 3.700 kilomètres. Ses missions seraient multiples : reconnaissance, renseignement et surveillance. Flexible, modulable, économique Il devrait également accompagner les avions de combat en soutien. Ainsi, le patron de la recherche chez Boeing a expliqué que quatre à six de ces avions pourront évoluer aux côtés d'un F/A-18 Super Hornet, l'avion de combat majoritaire des forces aériennes royales australiennes. Dans cette situation, en plus de pouvoir être télécommandé à partir du sol ou en l'air, l'appareil serait boosté par de l'intelligence artificielle pour pouvoir évoluer de façon autonome en sécurité lors des formations de vol serrées. Boeing expliquait également que pour réduire les coûts, l'avion sera propulsé par un seul réacteur provenant de l'aviation civile. Avec une telle motorisation, pour le moment, il est donc difficile de savoir quelles pourraient être ses limites en accompagnement d'un véritable avion de chasse. L'appareil sera développé entièrement par la filiale australienne de Boeing. Pour l'avionneur, ce sera d'ailleurs le plus grand budget consacré à un programme de drone en dehors des États-Unis. Ce développement sera soutenu par un investissement de près de 30 millions de dollars américains de la part du département de la défense du pays. Le premier vol d'un démonstrateur est prévu dès 2020, pour aboutir dans la foulée à la production en série d'un Airpower Teaming System directement opérationnel. https://www.futura-sciences.com/sciences/actualites/avion-boeing-devoile-son-avion-pilote-75181/
