A major technological breakthrough has arrived in computing world--- Quantum Computing is a reality. Recently a Canadian company D-wave demonstrated a viable quantum computer in Silicon Valley. Quantum computing get is name because it uses quantum mechanics rather than the conventional physics associated with digital processing, to drive the computation.
The quantum chip which is at the heart of quantum computing was designed by D-wave and built by NASA. Quantum chip is a processor built from the superconducting materials aluminum and niobium, chilled in a tank of helium. It achieves supercomputing speeds because its basic data units-called qubits, can hold both values “0” and “1” at the same time and also share those values with other qubits. The demonstration had a chip capable of running at 16 qubits and by end 2008 they are planning to reach 1024 qubits.
Quantum computers are not just faster than conventional computers. They change what computer scientists call the computational scaling of many problems.
