Quantum Maxwell’s demon ‘teleports’ entropy out of a qubit

Posted by in categories: computing, law, quantum physics

Researchers from the Moscow Institute of Physics and Technology, ETH Zurich, and Argonne National Laboratory, U.S, have described an extended quantum Maxwell’s demon, a device locally violating the second law of thermodynamics in a system located 1–5 meters away from the demon. The device could find applications in quantum computers and microscopic refrigerators cooling down tiny objects with pinpoint accuracy. The research was published Dec. 4 in Physical Review B.

The second law says that the entropy — that is, the degree of disorder or randomness — of an isolated system never decreases.

“Our demon causes a device called a qubit to transition into a more orderly state,” explained the study’s lead author Andrey Lebedev of MIPT and ETH Zurich. “Importantly, the demon does not alter the qubit’s energy and acts over a distance that is huge for quantum mechanics.”

What if consciousness is just a product of our non-conscious brain?

Posted by in category: neuroscience

‘’If we are indeed “subjects of unconscious authoring” then continuing to characterise psychological states in terms of being conscious and non-conscious is unhelpful. It constrains the theoretical understanding of psychological processes. ‘’

If consciousness is a by-product of our brains’ nonconscious processes, where does that leave us?

Researchers demonstrate teleportation using on-demand photons from quantum dots

Posted by in categories: cybercrime/malcode, quantum physics

A team of researchers from Austria, Italy and Sweden has successfully demonstrated teleportation using on-demand photons from quantum dots. In their paper published in the journal Science Advances, the group explains how they accomplished this feat and how it applies to future quantum communications networks.

Scientists and many others are very interested in developing truly —it is believed that such networks will be safe from hacking or eavesdropping due to their very nature. But, as the researchers with this new effort point out, there are still some problems standing in the way. One of these is the difficulty in amplifying signals. One way to get around this problem, they note, is to generate photons on-demand as part of a quantum repeater—this helps to effectively handle the high clock rates. In this new effort, they have done just that, using semiconductor .

Scientists added rabbit DNA to a houseplant, and now it’s an air purifier

Posted by in categories: biotech/medical, genetics

Plants are very good at producing oxygen that we all need in order to breath, but what about clearing the air of harmful chemicals? Past research has revealed that plants do a bit of housekeeping when it comes to cleaning the air of certain compounds but researchers wondered if they could help boost that function with a genetic tweak.

In new research published in Environmental Science & Technology, researchers explain how they were able to give a common house plant more power to clean the air around it, and it’s all thanks to DNA from a mammal.
