#Quantum 'world record' smashed

A fragile quantum memory state has been held stable at room temperature for a "world record" 39 minutes - overcoming a key barrier to ultrafast computers.

luiy's insight:

"Qubits" of information encoded in a silicon system persisted for almost 100 times longer than ever before.

 

Quantum systems are notoriously fickle to measure and manipulate, but if harnessed could transform computing.

 

The new benchmark was set by an international team led by Mike Thewalt of Simon Fraser University, Canada.

"39 minutes may not seem very long. But these lifetimes are many times longer than previous experiments”

"This opens the possibility of truly long-term storage of quantum information at room temperature," said Prof Thewalt, whose achievement is detailed in the journal Science.

In conventional computers, "bits" of data are stored as a string of 1s and 0s.

 

But in a quantum system, "qubits" are stored in a so-called "superposition state" in which they can be both 1s and 0 at the same time - enabling them to perform multiple calculations simultaneously.

How Social Activists are Transforming Digital Technologies

he Occupy movement is not only harnessing digital tools, but adding to the evolution of new media available to today’s advocates, developing new tools and appropriating existing ones. This first became apparent in the U.K., with the “Uncut” protests, where student protesters developed a new tool called Sukey to help each other avoid police barricades.
