Vint Cerf Doesn’t Think The Internet Is In Any Danger

Vint Cerf knows a thing or two about the Internet – he helped invent it. So, what does he think about all the doom and gloom that’s directed towards the future of the Internet? He’s not worried in the least. In a response to Danny Hillis’ concern that the Internet may one day fail, Cerf says the ubiquity of the …

German Physicists Build First Quantum Network

It was recently reported that scientists were able to overcome some of the problems with data degradation caused by computing in a quantum environment, and now Nature reports that physicists were able to build the first-ever working quantum network. Though, the the fibre optic network is in its infancy, as researchers reported a mere .2 percent accuracy in data that …

Scientists Create First Quantum Network

Scientists at the Max Planck Institute of Quantum Optics in Garching, Germany have successfully created the world’s first quatum network. A team of scientists led by Professor Gerhard Rempe, director at the institute and head of the Quantum Dynamics devision, set up the first elementary quantum network by coupling single-atom nodes that communicate quantum information via the coherent exchange of …

Quantum Computing Makes Another Leap Forward

Scientists have overcome a major hurdle facing quantum computing: how to protect quantum information from degradation by the environment while simultaneously performing computation in a solid-state quantum system. The research was reported in the April 5 issue of Nature. A group led by physicist Viatsheslav Dobrovitski made this big step forward on the path to using the motions of single …

Quantum Cryptography Foils Hackers

A research team led by University of Toronto Professor Hoi-Kwong Lo has found a new quantum encryption method to foil even the most sophisticated hackers. The discovery is outlined in a recent issue of Physical Review Letters. Quantum cryptography is, in principle, a foolproof way to prevent hacking. It ensures that any attempt by an eavesdropper to read encoded communication …

Quantum Computer Built Inside a Diamond

Diamonds are forever – or, at least, the effects of this diamond on quantum computing may be. A team that includes scientists from USC has built a quantum computer in a diamond, the first of its kind to include protection against “decoherence” – noise that prevents the computer from functioning properly. The demonstration shows the viability of solid-state quantum computers, …

IBM Banks Heavily On Quantum Computing

Scientific researchers at IBM Research in Yorktown Heights, N.Y. say they have come up with a quantum computing solution that harnesses the underlying quantum mechanics of Matter. The researchers say that they could deliver the technology within the next decade. A quantum computer would bring to reality a theoretical device capable of performing millions of computations at once. Matthias Steffen, …

Transistor the Size of a Single Atom Made

The race to build a quantum computer just got a huge boost. A team in Australia has constructed a transistor that is the size of a single atom. And, they say it is “perfect”. The tiny electronic device, described today in a paper published in the journal Nature Nanotechnology, uses as its active component an individual phosphorus atom patterned between …
