The Significance of Emerging Quantum Computers
Richard Feynman once used to say that no one understands quantum theory, followed by Stephen Hawking, The Grand Design, noting that using common sense is an inaccurate way to explain quantum physics. Such understandings will be demolished as quantum computer makes a breakthrough within 5 years. Emergence of quantum computation will force to change the common sense of this existing world.
Computers that we use today recognize a packet of data as a bit, which reads either 0 or 1. It computes as much as the number of bits present. In quantum theory a packet become a quantum bit, the information 0 and 1 with an ability of superposition. This allows to calculate 2 to the power of the number of Q-bit, where its output can be astronomical. The research group of quantum physics, with cooperations of several universities in UK, Japan, Israel and Netherlands, invented the first photonic chip that can be used for quantum computing.
Quantum theory exceeds the understanding of human common sense. It will became unclear to make a distinction between 0 and 1. “A system has not just one history but every possible history”, Feynman said. Crichton wrote a novel “Timeline”, a story of time travel by using quantum computer to eliminate any contradictions against the history of time. Q-bit allows 2n calculation, therefore huge numbers of parallel world is created as the number of photons is increased.
Quantum computer is not just a distributive computer using numbers of processors, but extreme distribution of calculation that single computer does. Using the quantum theory leaps even more developed encryption, as well as complex simulation to sight the world. Quantum computer will soon be a necessary tool for our practical living within a few decades. It also challenges our cognitive horizon at the same time, and changes our understanding of a new intelligence architecture.
