The world of technology has got one step closer to creating quantum computers. Dutch scientists have recently created a 2-qubit (quantum bit) processor running on a silicon chip.
While standard computers work with bits of information that can have only two states, 0 or 1, quantum processors are based on the fact that bits can exist in both states at the same time. As a result, they have the tremendous computing power and can do things that no classical computer can do. Quantum computers can be used for solving complex problems and can manage a much larger number of calculations at once.
Scientists explain that they are still in the early stages of developing a real quantum processor. Hardware manufacturer IBM has already built a 50-qubit computer, but with superconductive materials that need extreme cooling. Putting a quantum processor on a silicon chip, which is already used in the computer industry, maybe the first step toward mass production.
In such quantum processors, electrons can be in many states at once. This is called superposition. In the lab, scientists have managed to keep electrons between both positions at the same time, however, such electrons are not stable and quickly fall apart. By linking these electrons together on a silicon chip qubit hardware manufacturers could produce quantum processors for commercial use.
