New research has demonstrated a way to make bismuth electrons and nuclei work together as qubits in a quantum computer. The discovery, published in Nature Materials, takes us a key step further to creating practical quantum computing which could tackle complex programs that would otherwise take the lifetime of the universe to finish. The collaboration partners are based in the University of Warwick, UCL, ETH Zurich and the USA Sandia National Labs. Information on our normal computers...

Griffith Uni researchers lead light breakthrough Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise. The research collaboration, involving Griffith University, The University of Queensland and University of Science and Technology of China, was able to amplify the noisy quantum state of a single photon subjected to loss, without adding noise in the process; in fact, their amplification reduced...

A research team from the University of Bristol's Centre for Quantum Photonics (CQP) have brought the reality of a quantum computer one step closer by experimentally demonstrating a technique for significantly reducing the physical resources required for quantum factoring. The team have shown how it is possible to recycle the particles inside a quantum computer, so that quantum factoring can be achieved with only one third of the particles originally required. The research is published in...

Quantum Computing And Mechanics See Two Breakthroughs

April Flowers for redOrbit.com - Your Universe Online Two new studies, both published in Nature this week, outline incredible breakthroughs in the field of quantum mechanics. Australian engineers led an international team of researchers to create the first working quantum bit based on a single atom in silicon, potentially making another important step toward ultra-powerful quantum computing that theoreticians have dreamt of for decades. The team describes how they were able to read...

April Flowers for redOrbit.com - Your Universe Online An international team of researchers, including physicists from the University of Vienna and the Austrian Academy of Sciences, has achieved quantum teleportation over a record distance of 143 kilometers. The experiment marks a major step towards satellite-based quantum communication. The team transmitted quantum states between the two Canary Islands of La Palma and Tenerife over a distance of 143 kilometers, beating the previous...

Michael Harper for redOrbit.com — Your Universe Online Some of us were born naturally inclined to understand numbers and their relationships to one another. The rest of us, sadly, depend on the work of these mathematically savvy individuals just to function in everyday life. As such, while some may have no issues understanding prime numbers and calculating them in their heads, others may get a headache once they count past 10. There are computers that exist, of course, which can...
