Researchers develop key building block needed to make a quantum computer using silicon A team led by engineers and physicists at the University of New South Wales (UNSW) in Sydney, Australia, have developed one of the key building blocks needed to make a quantum computer using silicon: a "single electron reader". Their work was published today in Nature. Quantum computers promise exponential increases in processing speed over today's computers through their use of the "spin", or magnetic...

Research allows control of a single electron without disturbing other nearby electrons Researchers from two National Science Foundation (NSF)-funded Materials Research Science and Engineering Centers at Princeton University and the University of California, Santa Barbara made a significant breakthrough in the worldwide pursuit of quantum computing. They engineered a method to control the spin of a single electron within a magnetic field without disturbing other nearby electrons. The method...

A roundabout method of reading data can improve quantum memory Researchers who hope to create quantum computers are currently investigating various methods to store data. Nitrogen atoms embedded in diamond show promise for encoding quantum bits (qubits), but the process of reading the information results in an extremely weak signal. Now physicists have demonstrated a roundabout approach for generating a significantly stronger signal from these sorts of qubits. Their experiment is reported in...

An international team of scientists has performed the ultimate miniaturization of computer memory: storing information inside the nucleus of an atom. This breakthrough is a key step in bringing to life a quantum computer - a device based on the fundamental theory of quantum mechanics which could crack problems unsolvable by current technology. In the quantum world, objects such as atoms are allowed to exist in multiple states simultaneously -- that is, they could literally be in two places at...

Quantum computers that store information in so-called quantum bits (or qubits) will be confronted with a fundamental limitation. This is the claim made by Dutch theoretical physicists from the Foundation for Fundamental Research on Matter (FOM) and Leiden University in an article recently published in the journal Physical Review Letters. A quantum computer can only function if the information exists for long enough to be processed. The so-called coherence of the qubit ensures that the...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
