A quantum computer uses “qubits” that can exist in what is known as a superposition. Instead of being either 0 or 1 as is the case with conventional devices, they can be in both states simultaneously. Consequently, certain calculations can be performed simultaneously and far faster than ever before, solving problems that would require computing power that cannot be achieved with today’s systems. With operations that are thousands of times faster, quantum computers offer new possibilities, for instance, in searching through large databases, simulation of chemical and physical reactions, and in material design. However, this operating power may also enable attacks on currently used encryption algorithms that are practically impossible to break with the technologies available today.
