Diamond 'flaws' pave way for nanoscale MRI
Breakthrough offers high-sensitivity nanoscale sensors, and could lead to magnetic imaging of neuron activity and thermometry on a single living cell.
How losing information can benefit quantum computing
Suggesting that quantum computers might benefit from losing some data, physicists at the National Institute of Standards and Technology (NIST) have entangled—linked the quantum properties of—two ions ...
Electrified diamonds: Physicists on the trail of quantum information
With the help of tiny diamond crystals, physicists at the University of Basel have discovered new possibilities of quantum information: The scientists discovered at specific circumstances electric currents ...
Student creates world's largest quantum cluster
(Phys.org) —Australian National University PhD student Seiji Armstrong has made a quantum leap towards next-generation computing.
A fresh step towards quantum computing
The researcher Jose Ignacio Pascual of nanoGUNE, together with researchers of the Free University of Berlin, has developed a method to manipulate magnetism in atoms. This research makes it possible to drive forward the exploration ...
X-ray vision for road diggers: The next quantum leap?
Quantum mechanics has been hailed as the next big thing in technology. And quantum computers are a media favourite. But there is a little-known quantum technology that can peer beneath the earth, which could ...
Seeing a photon without absorbing it
Light is of fundamental importance. It allows us to see the world around us and record pictures of our environment. It enables communication over long distances through optical fibers. All current methods ...
Quantum world record smashed
A normally fragile quantum state has been shown to survive at room temperature for a world record 39 minutes, overcoming a key barrier towards building ultrafast quantum computers.
Distant artificial atoms cooperate by sharing light, physicists show
An international team of scientists has shown for the first time that atoms can work collectively rather than independently of each other to share light.
On-chip quantum buffer realized
Nippon Telegraph and Telephone Corp. has realized a quantum buffer integrated on an optical waveguide. The buffer is based on the "slow light effect", where the propagation speed of a pulsed light in a special ...
Physicists 'uncollapse' a partially collapsed qubit
Determining the quantum geometry of a crystal
Geometrical phases occur in many places in nature. One of the simplest examples is the Foucault pendulum: a tall pendulum free to swing in any vertical plane. Due to the earth rotation, the actual plane of ...
A single-atom light switch
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.
Diamond imperfections pave the way to technology gold
(Phys.org) —From supersensitive detections of magnetic fields to quantum information processing, the key to a number of highly promising advanced technologies may lie in one of the most common defects in ...
