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.
