What's the noise eating quantum bits?

Super powerful quantum computing relies on quantum bits, aka qubits, which are the equivalent of the classical bits used in today's computers. SQUIDs are being investigated for the development of qubits. However, system noise ...

New sensor devices recycle atoms

Next-generation sensors to be used in fields as diverse as mineral exploration and climate change will be turbo boosted thanks to University of Queensland and University of Sussex research.

How to outwit noise in quantum communication

How to reliably transfer quantum information when the connecting channels are impacted by detrimental noise? Scientists at the University of Innsbruck and TU Wien (Vienna) have presented new solutions to this problem.

Cleaning up quantum devices

A paper, based on NPL collaborative research, has been published in the journal Physical Review Letters The work paves the way for the identification and elimination of small amounts of surface defects whose presence on the ...

Bringing the chaos in light sources under control

Noise is an issue in optical telecommunications. And findings means of controlling noise is key to physicists investigating light-emitting diodes or lasers. Now, an Italo-Iraqi team has worked on a particular type of light ...

Scientists 'squeeze' light one particle at a time

A team of scientists has successfully measured particles of light being "squeezed", in an experiment that had been written off in physics textbooks as impossible to observe.
