The Many Moods of Decoherence

“I happen to dress based on mood.”
“But you essentially wear the same thing all the time.”
“Seemingly, but within that basic framework there are many subtle variations only discernible to an acute observer that reflect the many moods, the many shades, the many sides of George Costanza.”
“And what mood is this?”
“This is morning mist.”

Scientists have always believed that the quantum world–as strange as it is–was pretty clear in at least one thing.
Particles were either entangled. Or they weren’t. The entangled particle is an intimate state between particles that allows them to “communicate” over vast, spooky distances. The unentangled state is called, decoherence.
However, new research indicates that, like George Costanza’s many moods, decoherence comes in multiple variations.
Rainer Blatt and his team at at the Institute of Experimental Physics of the University of Innsbruck have been working  on creating a quantum computer.
The physicists have found not a single state of decoherence. The found several states or flavors when they exposed four entangled ions to a noisy environment.

“At the beginning the ions showed very strong connections,” says Julio Barreiro. “When exposed to the disturbing environment, the ions started a journey to the classical world. In this journey, their entanglement showed a variety of flavors or properties.”

Was one of them “morning mist”?
