Research: what is quantum, the sector for which Emmanuel Macron releases 1.8 billion euros?





Thecomputer quantum, or “the holy grail of IT“, summarizes Nicolas Chateauneuf in the newscast of the 20 Hours of France 2.”Imagine a machine 100 million times faster than the computers most powerful“, explains the journalist. computers of a new kind could indeed “revolutionize research“, in particular to develop”new drugs or vaccines by calculating the best assembly of molecules“, but also “to run more precise climate simulations, develop new materials or strengthen network security“.

The design of thecomputer quantum is different from those of computers current. “Even the most advanced still rely on microprocessors“capable of performing billions of operations per second and have a common language, binary, recalls Nicolas Chateauneuf.”The problem is that the race for performance runs up against the limits of miniaturization. While thecomputer quantum uses precisely quantum physics (…), it notably exploits a particularity which means that an atom, to simplify, can be in different places at the same time“. The calculations can therefore be done in parallel, superimposed, which”multiply the power“.
