In a recently leaked paper, the tech giant revealed to had built a quantum computer that solved a problem that would take traditional supercomputers 10,000 years. In the paper, Google says that it has achieved quantum supremacy, a major milestone towards the development of quantum computers.
Today’s computing is limited to having a single value of either 0 or 1 for each bit, quantum computing uses quantum bits (qubits) that are simultaneously in both states (0 and 1) at the same time. This phenomenon is called as the SUPERPOSITION. The consequence of this superposition is that quantum computers are able to test every solution to a problem at once. Further, because of this exponential relationship, such computers should be able to double their quantum computing power with each additional qubit.
