Two papers in this week's edition of Science report on research using quantum dots—solid state qubits—to make both a simple quantum logic ... gate, but the researchers who carried out this ...

Quantum logic gates between different isotopic species are ... of £270m over five years to help get quantum technology out of laboratories and into the marketplace. Oxford was chosen to lead ...

"Similar to building a huge wall out lots of small bricks, large quantum circuits require very many logic gates to function. However, if larger bricks are used the same wall could be built with ...

Scientists have for the first time demonstrated improvement in quantum computers by using codes designed to detect and discard errors in the logic gates of ... the entropy out of the system ...

Scientists have managed to make quantum Fredkin logic gates ... of the gate is a measure of how well this works: in our case, 99.9% precision means that, on average, 999 times out of 1,000 we ...

Classical computers deal with binary logic ... quantum computing. Now Steel and co-workers at Michigan, Michigan State, the Naval Research Laboratory and the University of California at San Diego have ...

Now a team of researchers has managed to create the world’s first quantum logic gate in faithful old silicon. Engineers from the University of New South Wales have developed a device that allows ...

One is the sheer number of elemental gates required to build quantum logic circuits ... The results show that the Toffoli carries out its most important and experimentally challenging quantum ...
