Copper compound as promising quantum computing unit

Quantum computers could vastly increase the capabilities of IT systems, bringing major changes worldwide. However, there is still a long way to go before such a device can actually be constructed, because it has not yet ...

Researchers report success with complex quantum states

Scientists from the Niels Bohr Institute at the University of Copenhagen have, for the first time, succeeded in producing, controlling and understanding complex quantum states based on two electron spins connected to a superconductor. ...

New tool for characterizing quantum simulators

Physicsts are developing quantum simulators, to help solve problems that are beyond the reach of conventional computers. However, they first need new tools to ensure that the simulators work properly. Innsbruck researchers ...

A quantum spin on molecular computers

If quantum computers existed, they would revolutionize computing as we know it. Based on fundamental properties of matter, the potential power of these theoretical workhorses would solve problems in a new way, cracking extremely ...

Researchers take two big steps toward quantum computing

(Phys.org)—"Spooky action at a distance," Einstein's famous, dismissive characterization of quantum entanglement, has long been established as a physical phenomenon, and researchers are keen to develop practical applications ...

What are these nanostars in 2D-superconductor supposed to mean?

Physicists from France and Russia have discovered magnetic disturbances in two-dimensional (2D) layered superconductors resembling small oscillating stars. These star-like electronic excitations are located around individual ...

Screens set to go green

Fitting the screens of electronic devices, such as televisions and smartphones, with a new display technology called 'organic light-emitting diodes' (OLEDs) will reduce their energy consumption, but such screens currently ...
