Researchers at ETH Zurich have shown that quantum states of single electron spins can be controlled by currents of electrons whose spins are evenly aligned. In the future, this method could be used in electronic circuit elements.
The quantum internet would be a lot easier to build if we could use existing telecommunications technologies and infrastructure. Over the past few years, researchers have discovered defects in silicon—a ubiquitous semiconductor ...
A joint research team that included members from Tohoku University has unveiled a new topological insulator (TI), a unique state of matter that differs from conventional metals, insulators, and semiconductors.
Deep under the ground at Fermi National Accelerator Laboratory is a brand-new quantum sensor and computing research center called QUIET, and at the surface—100 meters above—sits its twin called LOUD.
They say that one can miss the forest for the trees. But it's often worth taking a closer look at the trees to make sense of the dense, brambly whole. That's what a Stanford University group did to tackle a thorny quantum-information ...
In support of the development of large-scale superconducting quantum computers, researchers with the National Institute of Advanced Industrial Science and Technology (AIST), one of the largest public research organizations ...
Quantum computers hold the promise of being able to quickly solve extremely complex problems that might take the world's most powerful supercomputer decades to crack.
Quantum computers, computing devices that leverage the principles of quantum mechanics, could outperform classical computing on some complex optimization and processing tasks. In quantum computers, classical units of information ...
The entanglement of quantum systems is the foundation of all quantum information technologies. Complex forms of entanglement between several quantum bits are particularly interesting.
Researchers at the Universities of Melbourne and Manchester have invented a breakthrough technique for manufacturing highly purified silicon that brings powerful quantum computers a big step closer.
