Aberystwyth University scientist proposes a new mechanism for building quantum computers
A new mechanism for building quantum computers has been proposed by an international team of scientists led by Dr Daniel Klaus Burgarth at Aberystwyth University. Writing in the scientific journal Nature Communications ( http://www.nature.com/ncomms/index.html ), Dr Burgarth et al describe how the frequent observation of a basic building block of a quantum system, known as a qubit, could lead to the creation of far more powerful computers. The paper, Exponential rise of dynamic complexity in quantum computing through projections http://www.nature.com/ncomms/2014/141010/ncomms6173/full/ncomms6173.html is published today, Friday 10 October 2014. While the possibility of using quantum effects to develop a new type of computer has been known for over 30 years, only small “quantum computers” have been built until now. Scientists are now engaged in a world wide effort to build large quantum computers which will be able perform some very complex computations in a very short time, tasks tha...
