A revolution in the way computers workRELATED ARTICLES Quantum computing co Qedma raises $26mParticles that can be in several places at the same time could revolutionize the way computers work. One such particle that represents several numbers at once is called a "qubit" - the smallest processing unit in a quantum computer, equivalent to a "bit" in a standard computer. However, today IBM is considered the leading company in the development of a quantum computer and has unveiled a processor called Nighthawk that features 120 physical qubits. IBM's quantum computers and even Google's new chip are not yet efficient enough to compete with Nvidia's supercomputers, so they still have the image of an experimental project. "This is a scientific quantum advantage, but one that heralds the feasibility of reaching a commercial breakthrough within about three years," he says.
