Single-atom Bit Forms Smallest Memory In The World
2013-11-18 12:09:44

Karlsruhe Institute of Technology Control of the Magnetic Moment of Single Atoms Is the Key to Compact Data Memories and Quantum Computers One atom equals one bit: According to this design principle, we would like to construct magnetic data memories in the future. Presently, a compound of several million atoms is needed to stabilize a magnetic bit in a way that hard disk data are secure for several years. However, researchers from KIT have just made a big step towards a single-atom...

Quantum World Record Crushed
2013-11-14 15:37:00

University of Oxford 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. An international team including Stephanie Simmons of Oxford University, UK, report in this week's Science a test performed by Mike Thewalt of Simon Fraser University, Canada, and colleagues. In conventional computers data is stored as a string of 1s and 0s. In the experiment quantum bits...

Resonance In 'Artificial Atoms' Control Quantum Communication
2013-08-06 12:26:15

University of Copenhagen - Niels Bohr Institute Researchers at the Niels Bohr Institute, together with colleagues in the US and Australia, have developed a method to control a quantum bit for electronic quantum communication in a series of quantum dots, which behave like artificial atoms in the solid state. The results have been published in the scientific journal Physical Review Letters. In a conventional computer, information is made up of bits, comprised of 0's and 1's. In a quantum...

New Method To Distinguish Between Neighboring Quantum Bits
2013-06-18 09:01:59

University of New South Wales Researchers at the University of New South Wales have proposed a new way to distinguish between quantum bits that are placed only a few nanometers apart in a silicon chip, taking them a step closer to the construction of a large-scale quantum computer. Quantum bits, or qubits, are the basic building blocks of quantum computers - ultra-powerful devices that will offer enormous advantages for solving complex problems. Professor Michelle Simmons, leader of...

Quantum Internet With Combined Optical And Electrical Technique

Professor Weimin Chen and his colleagues at Linköping University, in cooperation with German and American researchers, have succeeded in both initializing and reading nuclear spins, relevant to qubits for quantum computers, at room temperature. The results have just been published in the renowned journal Nature Communications. A quantum computer is controlled by the laws of quantum physics; it promises to perform complicated calculations, or search large amounts of data, at a...

Australian Engineers Create Functional Quantum Bit Based On The Nucleus Of A Single Atom In Silicon
