According to a study published Wednesday in Nature, Google scientists announced a new step forward toward a future quantum computer with an experiment that significantly reduces the error rate, a major obstacle on the way to the “Holy Grail” of computing. .

A universal quantum computer will radically change computer systems, having enormous computing power, incomparable to the power of ordinary computers.

However, this revolutionary computer, which computer scientists consider the “Grail”, will not be possible soon, as many technological obstacles must be overcome, especially the too high error rate, to be able to develop reliable programs.

An experiment by Google’s Quantum AI research arm has shown that error correction can be vastly improved, allowing the digital giant to become a pawn in the quantum computing race.

Superconducting quantum processors, such as Google’s and rival IBM’s, use the amazing properties of quantum physics to control the world on an infinitesimally small scale.

They use quantum bits called qubits. These are the building blocks of quantum computing with an infinity of possible states that can overlap (0 and 1 at the same time) and become entangled, whereas classical computer bits have only two possible states (0 or 1). (full on Agerpres)
