  3. 3.  A qubit (or QUantum BIT) is similar in concept to a standard 'bit' - it is a memory element. It can hold not only the states '0' and '1' but a linear superposition of both states, α|0> +β |1> In physicicts terms, we denote the states |0> and |1> respectively.
  4. 4.  A quantum computer is a computer design which uses the principles of quantum physics in order to boost the computational power beyond what is attainable by a traditional computer.  These new generation computers represent the new paradigm for computing devices: computers whose components are individual quantum systems, and in which the properties of quantum mechanics are exploited to make possible new algorithms and new ways of processing information.
  5. 5.  DWAVE is a quantum computing company founded in 1999 in Canada ,in order to achieve its goal by making things happen now and avoid waiting 20 years to apply quantum computers in an efficient way …so It gathered a dedicated team of scientists and engineers to do researches. It came up with the quantum machine that blew the world with its unbelievable capacity.  The estimated cost of the commercialized DWAVE quantum computer is about $10,000,000 .
  6. 6. Faster Stronger
  7. 7.  It all began back to a 1959 speech by Richard Feynman , in which Richard spoke about the effects of miniaturization , including the idea of creating more powerful computers based on the quantum effects.  Before being able to realize this theory , scientists and engineers worked hard to fully develop a the technology of traditional computers . For this reason , over the years there was a little progress in the idea of bringing Feynman’s theory into reality.  The idea of quantum computing was first introduced by Yuri Manin in 1980 and Richard Feynman in 1982.
  8. 8.  Therefore , companies like GOOGLE , NASA and DWAVE have come together in order to build the world’s first quantum computer .
  9. 9.  Quantum computers were made, based on the quantum theory , covering superposition* , entanglement* , and tunneling.
  10. 10.  In fact , current computers were based on a binary system , where basically everything is either 0 or 1  With quantum computers , the base level can be 0 or 1 or both at the same time.  So , in addition to the standard binary bits , the computer also now uses quantum theory in order to create a qbit which can be both 1 or 0 or both at the same time.
  11. 11. Evolution of the number of qbits in quantum computers over the years 600 Number of qbits in the computer 500 400 300 200 100 0 2002 2003 2006 2007 2008 2011 2013
  12. 12. Quantum Computer Year 4q Calypso 2003 16q Europa II 2006 28q Leda 2007 128q Rainier 4 2010 512q Vesuvius 2012
  13. 13.  … while this photo is of an actual laboratory .
  14. 14.  “Quantum computers have the potential to solve problems that would take a classical computer longer than the age of the universe “ – Professor David Deutsch ,Oxford  In fact, the ability of quantum to solve problems thousands of times faster than traditional computers is attracting attention from some of the world's largest and most powerful institutions.
  15. 15.  Theory continues in advance , many researchers are looking for various algorithms and communication protocols to exploit the properties of quantum systems.
  16. 16.  Moreover, quantum computers can also be used to efficiently simulate other quantum systems. Perhaps some day quantum computers will be used to design the next generation of classical computers.  Qubits are interesting both from a physicist and an engineer's point of view and are definitely worth investigating further. With enough qubits, it is possible to run quantum computations, which can outperform current technology in some specific cases, and may provide other means of replacing (or enhancing) semiconductor systems. The fabrication technology is improving all the time and soon qubits will be routinely implemented into superconducting circuits.  In fact ,DWAVE are working more and more to commercialize their product and make it suitable for everyone’s use.  Finally, no one knows what DWAVE will come up in the coming years , but definitely it is going to be a quantum pc filled with huge numbers of bits overpassing the 512 qbit superconducting Vesuvius.
