Immunizing quantum computers against errors

EurekAlert   -   Scientific News Websites

Researchers at ETH Zurich have used trapped calcium ions to demonstrate a new method for making quantum computers immune to errors. To do so, they created a periodic oscillatory state of an ion that circumvents the usual limits to measurement accu...

Now you see heat, now you don't

EurekAlert   -   Scientific News Websites

Hiding an object from heat-sensing cameras could be useful for military and technology applications as well as for research. Efforts to develop such a method have been underway for decades with varying degrees of success. Now, researchers report i...

Yale researchers create a 'universal entangler' for new quantum tech

EurekAlert   -   Scientific News Websites

One of the key concepts in quantum physics is entanglement, in which two or more quantum systems become so inextricably linked that their collective state can't be determined by observing each element individually. Now Yale researchers have d...

'Immunizing' quantum bits so that they can grow up: New material enhances supercurrent in topological-insulator nanoribbon Josephson junctions

ScienceDaily   -   General News Websites

Qubits need a better immune system before they can grow up. A new material, engineered into a thin strip, is one step closer to 'immunizing' qubits against noise, such as heat and other parts of a computer, that interferes with how well ...

'Immunizing' quantum bits so that they can grow up

Phys.org   -   Scientific News Websites

Quantum computers will process significantly more information at once compared to today's computers. But the building blocks that contain this information – quantum bits, or "qubits" – are way too sensitive to their surroundings to ...
