Software & Hardware
P 7WORKSHOP QUANTUM COMPUTING, BPI FRANCE, JUNE 20, 2019
• Go beyond the limitations of classical computing
• Massively parallel processing (entangled qubits registers ↦ #operations = exp(#qubits)
• Open up new application areas : chemistry, material science, optimization
• Success lies in the joint development of dedicated hardware and software
• Find repercussion in financial markets, big data, large industries, army, and State in general…
• Quantum computing is a multi-facetted technology, and of strategical importance

QUANTUM COMPUTING
AN EXAMPLE OF ADVANCED APPLICATION2
P 9
• Planning & cohesion of the territories
• Multi-scalar flux optimization (transport of individuals and energy, etc.) within established
networks of human beings, such as Metropoles (intra & inter)
• Increased meshing of service access (transport network, internet & information capabilities,
etc.)
➢ Impact on transport networks (flux & access), energy (distribution & access), communication,
& diffusion (technologies, education, culture)
Of strategical importance for the Ministry for the Cohesion of the Territories

QUANTUM COMPUTING
VISION ON THE NEEDS / TIMESCALE2
• 0 – 5 years
• Protected logical qubits using error corrections or topologically
• New quantum algorithms (predictive, error correction)
• Influence of algorithms on hardware architectures (2D, 3D) and conversely
• 5 – 10 years
• Middle-size Q processors solving problems in Q chemistry (novel molecules),
Material Science (high-Tc supra), and Machine Learning
• Optimization of data flux (energy, individuals, smart grids, transport, etc.)
• > 10 years
• Integration of large-scale Q processors, including control systems
• Quantum/classical advantage for complex mathematical problems (factorization)
• Hardware/Software/Error Correction joint optimization (fault-tolerant)

INTEGRATION CHALLENGES2
P 12
• How to scale up ?
• Ability to manipulate from several to hundreds (already a challenge), even thousands of logical qubits
• Integrate auxiliary qubits for error correction
• Future architectures with error correcting codes
• Software-to-Hardware influence ↦ substantial reduction of the necessary auxiliary qubits
• Control and read-out systems of the Quantum registers
• Identify suitable interfaces
• Classical ↔︎ Quantum
• Between the qubit carriers (spins, photons, superconducting, etc.)
• End-user ↔︎ Machine
• Solutions compatible with industrialization
• Large scale design and fabrication quality
• Political importance : national sovereignty, resource sustainability, energy consumption, etc.
