Quantum Computing: The Future of IT as We Know It?Book Now
‘Quantum Computing: The Future of IT as We Know It?’
Quantum Computing and quantum computers are believed by many to be the future of high-performance computing. Quantum computing, we're meant to understand, is set to change the world. But despite its promise, it's neither widely available nor particularly useful yet. Or is it soon set to be?
A quantum computer is a computer that makes use of quantum physics and - unlike a normal digital systems which rely on data encoded into binary digits or bits —quantum computation uses quantum properties to represent data and perform operations. A quantum computer uses not bits but qubits (quantum bits). Each of its qubits can represent a 0, a 1, or—crucially—anything in between. We’re into Schrödinger and Heisenberg territory now!
Because each qubit can assume such a wide range of values, a modest number of them can hold a gigantic quantity of information; this is what lends quantum computers their theoretical power. Just 100 qubits can store 1,267,650,600,228,229,401,496,703,205,375 different numbers—many trillion times the storage capacity of all computers ever made
Recent announcements have given enormous impetus to further work: Scientists have achieved an “exciting breakthrough” in quantum computing, creating a solid state memory system made from silicon that was operational at room temperature for 39 minutes.
This achievement breaks one of the major barriers to building quantum computers: the need to run the systems at incredibly cold temperatures. The previous record for storing information at room temperature in a quantum computer was just 25 seconds.
Although 39 minutes may not sound like a long time, but since a single operation on a quantum computer takes just one-hundred-thousandth of a second, this means that theoretically over 20 million operations could be performed before the qubits’ data decayed by one per cent.
BOOK HERE to find out more, examine what ‘Quantum Computing’ really is, gain further insight into how it might well change the face of computing and IT as we know it and how it can be used to all our advantage - and perhaps disadvantage - and to ask very difficult questions of our world-renowned speaker at the Real Time Club dinner and debate on Tuesday 17th December 2013
Professor Jeremy O’Brien
Jeremy O'Brien is professor of physics and electrical engineering and Director of the Centre for Quantum Photonics (CQP) at the University of Bristol, developing what is believed to be the Government’s 9th Great Technology – Quantum Technologies and Processes – which are the forerunner science and technologies leading to true Quantum Computing and the first true quantum computers.
Jeremy received his Doctorate in physics from the University of New South Wales in 2002 for experimental work progressing towards the fabrication of devices for a silicon quantum computer.
CQP's efforts are focused on the fundamental and applied quantum mechanics at the heart of quantum information science and technology, in particular leading to prototypes for scalable quantum computing.
