Austrian and Chinese scientists have succeeded in teleporting three-dimensional quantum states for the first time. High-dimensional teleportation could play an important role in future quantum computers.

Researchers from the Austrian Academy of Sciences and the University of Vienna have experimentally demonstrated what was previously only a theoretical possibility. Together with quantum physicists from the University of Science and Technology of China, they have succeeded in teleporting complex high-dimensional quantum states. The research teams report this international first in the journal Physical Review Letters.

Practical anonymous communication protocol developed for quantum networks

Posted by in categories: internet, quantum physics

The ability to securely transmit information over the internet is extremely important, but most of the time, eavesdroppers can still generally determine who the sender and receiver are. In some highly confidential situations, it is important that the sender’s and receiver’s identities remain anonymous.

Over the past couple of decades, researchers have been developing protocols for anonymously transmitting messages over classical networks, but similar protocols for are still in much earlier stages of development. The anonymity methods that have been proposed for quantum networks so far face challenges such as implementation difficulties or require that strong assumptions be made about the resources, making them impractical for use in the .

In a new paper, Anupama Unnikrishnan, Ian MacFarlane, Richard Yi, Eleni Diamanti, Damian Markham, and Iordanis Kerenidis, from the University of Oxford, MIT, Sorbonne University, the University of Paris and CNRS, have proposed the first practical for anonymous communication in quantum networks.

“Qutrit”: Complex quantum teleportation achieved for first time

Posted by in categories: computing, particle physics, quantum physics

Researchers from the Austrian Academy of Sciences and the University of Vienna have experimentally demonstrated what was previously only a theoretical possibility. Together with quantum physicists from the University of Science and Technology of China, they have succeeded in teleporting complex high-dimensional quantum states. The research teams report this international first in the journal “Physical Review Letters”.

In their study, the researchers teleported the quantum state of one photon (light particle) to another distant one. Previously, only two-level states (“qubits”) had been transmitted, i.e., information with values “0” or “1”. However, the scientists succeeded in teleporting a three-level state, a so-called “qutrit”. In quantum physics, unlike in classical computer science, “0” and “1” are not an ‘either/or’ – both simultaneously, or anything in between, is also possible. The Austrian-Chinese team has now demonstrated this in practice with a third possibility “2”.

Novel experimental method.

Newly Discovered State of Matter Could Vastly Enhance Computing

Posted by in categories: computing, quantum physics

A team of physicists claims to have discovered a new state of matter — a breakthrough that could vastly improve traditional as well as quantum computing.

The new state, called “topological superconductivity,” could help to increase storage capabilities in electronic devices and enhance quantum computing.

A classic quantum theorem may prove there are many parallel universes

Posted by in categories: cosmology, particle physics, quantum physics

By Leah Crane

Some ideas about the quantum world appear to suggest there are many versions of you spread out across many parallel universes. Now, two scientists have formulated a proof that attempts to show this is really true.

The proof involves a fundamental construct in quantum mechanics called Bell’s theorem. This theorem deals with situations where particles interact with each other, become entangled, and then go their separate ways. It is what’s called a “no-go theorem”, one designed to show that some assumption about how the world works is not true.
