SCIENTISTS now are expecting quantum communications to fundamentally change human development over the next two or three decades, as there is enormous potential in applying the next generation communication technology to fields like military and finance.

    In addition to quantum communications, quantum computers have also drawn attention from scientists and governments worldwide.

    Quantum computing could dwarf the processing power of today’s supercomputers.

    In normal silicon computer chips, data is rendered in one of two states: 0 or 1. However, in quantum computers, data can exist in both states simultaneously, creating a capacity for exponentially more information.

    One analogy to explain the concept of quantum computing is that it is like being able to read all the books in a library at the same time, whereas conventional computing is like having to read them one after another.

    Scientists say that a quantum computer will take just 0.01 second to deal with a problem that takes Tianhe-2, one of the most powerful supercomputers in the world, 100 years to solve.  (SD-Xinhua)
