Researchers may have overcome a crucial hurdle in quantum computing. They've demonstrated a two-qubit logic gate, which is the central building block of a quantum computer.
Researchers at NIST have managed to teleport quantum information over 100 kilometers of optical fiber, which is four times farther than the previous record.
Scientists may already be working on a way to secure data for the quantum computers of the future.
Physicists have revealed a new quantum computation scheme in which operations occur without a well-defined order, which may be able to accomplish a task more efficiently than a standard quantum computer.
Robots, mathematics, physics, climate simulations: All of these things rely on computers and computing. Computers, though, are quickly reaching their limits; they simply aren't fast enough and can't store enough information with smaller amounts of space.
Scientists have taken a closer look at quantum computing and have found that quantum tools can help robots learn and respond much faster to the stimuli around them.
Quantum computers have the potential to revolutionize the way computations are performed. Now, scientists may be one step closer to creating such a computer; they've demonstrated a new level of reliability in a five-qubit array.
Quantum computing could be closer than ever. Scientists have used a laser to place individual rubidium atoms near the surface of a lattice of light, which means that there's a new method for connecting particles which, in turn, could help develop quantum computing systems.
A new and innovative computing machine is currently attracting a great deal of attention in specialist circles. A team under the leadership of Matthias Troyer, a professor at ETH Zurich, has now confirmed that the machine uses quantum effects. However, it is not any faster than a traditional compute...
An international research group of scientists and engineers led by the University of Bristol, UK, has made an important advance towards a quantum computer by shrinking down key components and integrating them onto a silicon microchip.
Radical new treatments for cancer could be available in hospitals in 2014, while quantum computing could allow scientists to model chemical reactions at the atomic level for the first time – these are some of the predictions made by researchers in Horizon’s poll of major developments this year. ...
With just a single atom, light can be switched between two fibre optic cables at the Vienna University of Technology. Such a switch enables quantum phenomena to be used for information and communication technology.
