Important performance indicators for quantum devices can be traced back to chip design, material quality and defect density. In addition, nano- and micro-fabrication are crucial, as quantum states are ...

(Nanowerk News) Synthetic diamond is durable, inert, rigid, thermally conductive and chemically well-behaved – an elite material for both quantum and conventional electronics. But there’s one problem.

Superconducting quantum devices and arrays constitute a cutting‐edge field at the intersection of superconductivity and quantum mechanics. These systems utilise superconducting circuits—typically ...

Artist’s impression of the quantum spin Hall effect in a graphene-based spintronic device, integrated in a chip. The blue and red spheres are spin-up and spin-down electrons traveling along the edge ...

Researchers have realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution demands. Unlike the ...

Quantum algorithm company Phasecraft Ltd. announced today that it has raised $34 million in new funding to accelerate its work to transform quantum computing’s theoretical promise into practical ...

Researchers from the RIKEN Center for Quantum Computing and Huazhong University of Science and Technology have conducted a theoretical analysis demonstrating how a “topological quantum battery”—an ...

Scientists built a tiny clock from single-electron jumps to probe the true energy cost of quantum timekeeping. They discovered that reading the clock’s output requires vastly more energy than the ...

Imagine a world where quantum devices don’t need to hide inside bulky refrigerators colder than outer space. For decades, this has been the biggest roadblock as quantum states vanish unless they are ...
