Quantum Computing

Tricking the perfect code machine

They don't often pose for goofy photographs - the members of the Quantum Hacking group at the Norwegian University of Science and Technology (NTNU), and the Centre for Quantum Technologies at the National University of Singapore. But everyone wants their picture taken with Eve.

Team's quantum object is biggest by factor of billions

Researchers have created a "quantum state" in the largest object yet. Such states, in which an object is effectively in two places at once, have until now only been accomplished with single particles, atoms and molecules.

Quantum computing: Is it possible, and should you care?

What is a quantum computer and when can I have one? It makes use of all that "spooky" quantum stuff and vastly increases computing power, right? And they'll be under every desk when scientists finally tame the spooky stuff, right? And computing will undergo a revolution no less profound than the one

Quantum computing device hints at powerful future

One of the most complex efforts toward a quantum computer has been shown off at the American Physical Society meeting in Dallas in the US. It uses the strange "quantum states" of matter to perform calculations in a way that, if scaled up, could vastly outperform conventional computers.

Quantum computing could head to 'the cloud', study says

Quantum computing will use the inherent uncertainties in quantum physics to carry out fast, complex computations. This "blind quantum computing" can be carried out without a cloud computer ever knowing what the data is.

Quantum computer slips onto chips

Researchers have devised a penny-sized silicon chip that uses photons to run Shor's algorithm - a well-known quantum approach - to solve a maths problem.

Quantum computing

Quantum computing is the use of quantum-mechanical phenomena such as superposition and entanglement to perform computation. Computers that perform quantum computation are known as a quantum computers.

D-Wave Systems

D-Wave Systems, Inc. [2] is a quantum computing company, based in Burnaby, British Columbia, Canada. D-Wave is the world's first company to sell computers which exploit quantum effects in their operation.

Spin-based electronics gets boost

The next generation of computers may make use of the "spin" of electrons instead of their charge. Spintronics relies on manipulating these spins to make them capable of carrying data.
