(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 ...
Physicists at EPFL propose a new "quantum simulator": a laser-based device that can be used to study a wide range of quantum systems. Studying it, the researchers have found that photons can behave like magnetic dipoles at ...

The field of experimental quantum communication promises ways of efficient and unconditional secure information exchange in quantum states. The possibility of transferring quantum information forms a cornerstone of the emerging ...
Superconducting circuits, which have zero electrical resistance, could enable the development of electronic components that are significantly more energy-efficient than most chips used today. Importantly, superconducting ...
The discovery of superconductivity more than a century ago has significantly changed our world.
A research group at the NIMS International Center for Materials Nanoarchitectonics (MANA) has proved that the electrical resistance of a metal single atomic layer on a silicon surface becomes zero by superconductivity.
