Unusual quantum liquid on crystal surface could inspire future electronics

Posted by in categories: particle physics, quantum physics

For the first time, an experiment has directly imaged electron orbits in a high-magnetic field, illuminating an unusual collective behavior in electrons and suggesting new ways of manipulating the charged particles.

The study, conducted by researchers at Princeton University and the University of Texas-Austin was published Oct. 21, in the journal Science. The study demonstrates that the electrons, when kept at very low temperatures where their quantum behaviors emerge, can spontaneously begin to travel in identical elliptical paths on the surface of a crystal of bismuth, forming a quantum fluid state. This behavior was anticipated theoretically during the past two decades by researchers from Princeton and other universities.

“This is the first visualization of a quantum fluid of electrons in which interactions between the electrons make them collectively choose orbits with these unusual shapes,” said Ali Yazdani, the Class of 1909 Professor of Physics at Princeton, who led the research.

Stanford created scalable optical quantum annealing computer using special lasers and electrical circuits

Posted by in categories: computing, quantum physics

An entirely new type of computer that blends optical and electrical processing could get around this impending processing constraint and solve superlarge optimization problems. If it can be scaled up, this non-traditional computer could save costs by finding more optimal solutions to problems that have an incredibly high number of possible solutions.

There is a special type of problem – called a combinatorial optimization problem – that traditional computers find difficult to solve, even approximately. An example is what’s known as the “traveling salesman” problem, wherein a salesman has to visit a specific set of cities, each only once, and return to the first city, and the salesman wants to take the most efficient route possible. This problem may seem simple but the number of possible routes increases extremely rapidly as cities are added, and this underlies why the problem is difficult to solve.

Glad to see others sharing this perspective.


Quantum effects could be the key to unlocking the mystery of machine learning, and maybe even consciousness.

Biocentrism: Where The SOUL Goes After Death [VIDEO]

Posted by in categories: chemistry, life extension, neuroscience, quantum physics

Now, from the wild side.


Quantum Theory Proves Consciousness Moves To Another Universe After Death. There is an interesting new theory emerging from a scientist long familiar with physics, quantum mechanics and astrophysics. Biocentrism teaches that life and consciousness are fundamental to the universe. It is consciousness that creates the material universe, not the other way around. At least, the new thinking that has given birth to the new theory of biocentrism, which the professor, Dr. Robert Lanza, freely espouses. Lana has been voted the 3rd most important scientist alive by the NY Times. Lanza is an expert in regenerative medicine and scientific director of Advanced Cell Technology Company. Before he has been known for his extensive research which dealt with stem cells, he was also famous for several successful experiments on cloning endangered animal species. Biocentrism—is a concept proposed in 2007 by American doctor of medicine Robert Lanza, a scientist in the fields of regenerative medicine and biology, which sees biology as the central driving science in the universe, and an understanding of the other sciences as reliant on a deeper understanding of biology. Biocentrism states that life and biology are central to being, reality, and the cosmos—consciousness creates the universe rather than the other way around. It asserts that current theories of the physical world do not work, and can never be made to work, until they fully account for life and consciousness. While physics is considered fundamental to the study of the universe, and chemistry fundamental to the study of life, biocentrism claims that scientists will need to place biology before the other sciences to produce a theory of everything.

Quantum Teleportation Could Revolutionize Modern Phone And Internet Communication

Posted by in categories: encryption, finance, internet, mobile phones, quantum physics, space, transportation

I never get tired of articles highlighting the potential around leveraging Quantum teleporting as a method to replace networks and communications. Now the real question is how soon and how much of the existing infrastructure will need to be replaced to begin taking advantage of this technology earlier than others? As with most things, governments are often early adopters as well as Financial Services and ISPs are a close 2nd in the adoption of such technologies.


An experiment conducted about quantum teleportation could improve and transform the modern phone and Internet communication by having highly secure and encrypted messaging.

A recent study has suggested that comet outbursts are caused by avalanches and not geysers.

New 3D wiring technique brings scalable quantum computers closer to reality

Posted by in categories: computing, quantum physics

Great advancement around how to make QC available on small scale devices.


Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

“The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits,” said Jeremy Béjanin, a PhD candidate with IQC and the Department of Physics and Astronomy at Waterloo. He and Thomas McConkey, PhD candidate from IQC and the Department of Electrical and Computer Engineering at Waterloo, are lead authors on the study that appears in the journal Physical Review Applied as an Editors’ Suggestion and is featured in Physics. “The technique connects classical electronics with quantum circuits, and is extendable far beyond current limits, from one to possibly a few thousand qubits.”
