Tiniest spin devices becoming more stable

(Phys.org)—In 2011, the research group of Roland Wiesendanger, Physics Professor at the University of Hamburg in Germany, fabricated a spin-based logic device using the spins of single atoms, a feat that represents the ...

Researchers build first 3D magnetic logic gate

(Phys.org) —The integrated circuits in virtually every computer today are built exclusively from transistors. But as researchers are constantly trying to improve the density of circuits on a chip, they are looking at alternative ...

New spin control method brings billion-qubit quantum chips closer

Australian engineers have discovered a new way of precisely controlling single electrons nestled in quantum dots that run logic gates. What's more, the new mechanism is less bulky and requires fewer parts, which could prove ...

Full control of a six-qubit quantum processor in silicon

Researchers at QuTech—a collaboration between the Delft University of Technology and TNO—have engineered a record number of six, silicon-based, spin qubits in a fully interoperable array. Importantly, the qubits can be ...

Researchers build switchable magnetic logic gate

(Phys.org)—A team of scientists from several research centers in South Korea, has succeeded in building a logic circuit that is based on switchable magnetism, rather than electronics. They describe their research and a ...

Researchers find possible evidence of Majorana fermions

(Phys.org) -- Researchers working out of Delft University of Technology in the Netherlands have constructed a device that appears to offer some evidence of the existence of Majorana fermions; the elusive particles that are ...

Sustained quantum information processing demonstrated

Raising prospects for building a practical quantum computer, physicists at the National Institute of Standards and Technology have demonstrated sustained, reliable information processing operations on electrically charged ...
