Quantum physics and modern technology came a step closer together this week with announcements from Canadian company, D-Wave, who claim to be ready to produce the first quantum computer.
Simplified, this means that computers as we know them process data by passing electrons through transistors. A ‘bit’, representing a simple unit of information is represented by a ‘1’ or a ‘0’. A quantum computer works on the laws of quantum physics, dealing with energy and matter at atomic levels. Data would be processed using caged atoms known as quantum bits or Qubits. A qubit can also represent a ‘1’ or a ‘0’ but more importantly can be both at the same time.
This will allow the quantum computer to speed the processing of information to a scale beyond our current comprehension. Problem solving that uses massive amounts of data and variables could be dealt with simultaneously. Unlike to be on your desk at any time in the future, it is hoped these computers will be developed for use in applications such as the searching of vast databases, creating uncrackable ciphers or simulating atomic structures of substances.
Surely, if an ‘uncrackable’ cipher could be created with a quantum computer, it could just as easily be cracked with another, thus defeating the object?
Some scientists have dismissed these claims because they haven’t seen any concrete proof, like D-Wave are going to be showing off their ideas for other people to steal! However, they would do well to remember what happened the last time somebody messed with atoms for the greater good of mankind.
