While digital computing requires data to be encoded into binary digits (definite states 0 or 1), quantum computation uses quantum bits (qubits), which is usually in superposition of states.
Quantum computing was initiated by the work of Yuri Manin and Paul Benioff in 1980, and often conceived to be of theoretical similarities with non-deterministic and probabilistic computers.
Albeit, the development of actual quantum computers is still in its infancy, successful experiments have been carried out in which quantum computational operations were executed on a small number of quantum bits.
It is invariably the technology that many scientists, and big businesses expect to provide a so-called quantum leap into the future of computing.
As large-scale quantum computers, according to the theory, would be able to solve certain problems much more quickly than any digital computer using even the best currently known algorithms.
Meanwhile, Google is reportedly testing new encryption technology that could protect its Chrome web browser from attackers using quantum computers. Which may perhaps prompt the question; has the age of quantum computing arrived?
