Theorists smooth the way to modeling quantum friction: New paradigm offers a strategy for solving one of quantum mechanics’ oldest problems

Posted by in categories: chemistry, computing, nanotechnology, particle physics, quantum physics

Princeton’s answer to Quantum friction.


Abstract: Theoretical chemists at Princeton University have pioneered a strategy for modeling quantum friction, or how a particle’s environment drags on it, a vexing problem in quantum mechanics since the birth of the field. The study was published in the Journal of Physical Chemistry Letters.

“It was truly a most challenging research project in terms of technical details and the need to draw upon new ideas,” said Denys Bondar, a research scholar in the Rabitz lab and corresponding author on the work.

Quantum friction may operate at the smallest scale, but its consequences can be observed in everyday life. For example, when fluorescent molecules are excited by light, it’s because of quantum friction that the atoms are returned to rest, releasing photons that we see as fluorescence. Realistically modeling this phenomenon has stumped scientists for almost a century and recently has gained even more attention due to its relevance to quantum computing.

A&S Physicist Awarded IBM Grant to Develop Quantum Computing

Posted by in categories: computing, quantum physics

So, IBM is giving grant money to A&S to build a Quantum Computer. Hmmm; so IBM announced they had a Quantum Computer and computing services via cloud. Guessing IBM has a pseudo version of QC given this move.


A physicist in the College of Arts and Sciences has been awarded a major grant to help develop quantum computing technology.

Britton Plourde, associate professor of physics, is using a three-year, $900,000 grant from IBM to conduct research for the LogiQ Program. LogiQ is part of the Intelligence Advanced Research Projects Activity (IARPA), based in the Office of the Director of National Intelligence.

Chief Scientist at Security Innovation Presents on Quantum Safety at Fourth International Cryptographic Module Conference

Posted by in categories: cybercrime/malcode, encryption, information science, quantum physics

I am glad that D. Whyte recognizes “If quantum computers are developed faster than anticipated, certification would mandate insecure modules, given the time to approve and implement new quantum resistant algorithms. Worse, it is conceivable that data encrypted by a certified module is more vulnerable than data encrypted by a non-certified module that has the option of using a quantum-safe encryption algorithm.”

Because many of us who are researching and developing in this space have seen the development pace accelerated this year and what was looking like we’re 10 years away is now looking like we’re less than 7 years.


Dr. William Whyte, Chief Scientist for Security Innovation, a cybersecurity provider and leader in the 2015 Gartner Magic Quadrant for Security Awareness Training, will be presenting at the Fourth International Cryptographic Module Conference in Ottawa, Ontario.

QC will change many industries and even some fortunes as well

Posted by in categories: computing, economics, employment, quantum physics

QC will change many industries and even some fortunes as well. So, no wonders Canada & Australia both deem it as a priority.


Mike Lazaridis, founder of Blackberry Limited and the visionary who led the establishment of the Perimeter Institute for Theoretical Physics (PI), the Institute for Quantum Computing (IQC) at the University of Waterloo and Quantum Valley Investments, delivered a keynote address highlighting the Quantum Valley model in Waterloo Region, Ontario, Canada and the emphasis both federal and provincial governments have placed on the development of quantum technologies.

The Quantum Europe conference comes at a time when large scale investments from tech companies and governments around the world, including in Canada, are being made as part of the “Second Quantum Revolution” – a new global industry fueled by the commercialization of new transformative quantum technologies.

AI Research Tool Runs Experiment that won 2001 Nobel Prize in Physics

Posted by in categories: computing, information science, quantum physics, robotics/AI

Australian physicists’ team has developed a new research assistant to carry out experiments in quantum mechanics in an artificial intelligence (AI) algorithm form, which quickly took control of the experiment, learned the job tasks and even innovated. In a statement, co-lead researcher Paul Wigley from the Australian National University (ANU) Research School of Physics and Engineering, said he didn’t expect that the machine would be able to conduct the experiment itself from scratch within an hour.

He added that in case a simple computer program had been used, it would have taken much more time than the age of the universe to go through all the combinations and work on it.

Scientists were looking forward to reconstruct an experiment that was awarded the 2001 Nobel Prize in Physics, which included very cold gas trapped in a laser beam called a Bose-Einstein condensate.

U.S. Navy’s SPAWAR will pay D-Wave $11 million for quantum computer training

Posted by in categories: computing, military, quantum physics, robotics/AI, virtual reality

US Navy paying D-Wave to train them on QC.


A division of the U.S. Navy intends to pay Canadian company D-Wave $11 million to learn how to use its quantum computing infrastructure, according to a federal filing posted online on Monday.

The unit seeking this training is the Navy’s Space and Naval Warfare Systems Center Pacific, known as SPAWAR or SSC-PAC for short, which is headquartered in San Diego and has previously researched amphibious throwable robots, unmanned aerial vehicles, virtual reality, and many other technologies. The filing does not actually cover the cost of quantum computing hardware. But NASA has been allowing SPAWAR scientists to learn how to use the D-Wave machine that it operates with Google at the NASA Ames Research Center, the San Diego Union-Tribune reported last month.

Can We Receive Messages from the Future?

Posted by in categories: computing, mathematics, quantum physics, time travel

About ten years ago scientist Dave Bacon, now at Google, presented that a time-travelling quantum computer could rapidly solve a bunch of problems, known as NP-complete, which mathematicians have lumped together as being hard. The problem was, Bacon’s quantum computer was travelling around ‘closed timelike curves’. These are paths through the fabric of spacetime that loop back on themselves. General relativity lets such paths to exist through contortions in spacetime identified as wormholes.

Why send a message back in time, but lock it so that no one can ever read the contents? As it may be the key to resolving presently intractable problems. That’s the claim of an international collaboration.

Mason researchers keep networks moving to stay safe from hacker attacks

Posted by in categories: cybercrime/malcode, information science, internet, quantum physics

Given the fact that Los Alamos Labs have been and continue to advance cyber security work on the Quantum Internet as well as work in partnerships with other labs and universities; so, why isn’t Mason not collaborating with Los Alamos on developing an improved hacker proof net? Doesn’t look like the most effective and cost efficient approach.


Imagine burglars have targeted your home, but before they break in, you’ve already moved and are safe from harm.

Now apply that premise to protecting a computer network from attack. Hackers try to bring down a network, but critical tasks are a step ahead of them, thanks to complex algorithms. The dreaded “network down” or denial of service message never flashes on your screen.

Researchers construct a quantum counterpart of classical friction, a velocity-dependent force acting against the direction of motion. In particular, a translationary invariant Lindblad equation is derived satisfying the appropriate dynamical relations for the coordinate and momentum (i.e., the Ehrenfest equations). Numerical simulations establish that the model approximately equilibrates. (© ACS)

Scientists Find New Light Form — And It Changes Everything

Posted by in categories: internet, quantum physics

A new form of light which makes fiber optics more secure. Los Alamos has been key player in this space due to their work on the Quantum Internet.


In a breakthrough that has the potential to alter our understanding of the fundamental nature of light, scientists from the Trinity College Dublin School of Physics and the CRANN Institute in Ireland have discovered a never before seen new form of luminescence.

Lead author Paul Eastham attests to how exciting this finding is, saying in a statement that this very fundamental property of light that has always been thought to be constant can, in fact, change.
