Using Enzymes to Enhance LEDs

Posted by in categories: computing, engineering, particle physics, quantum physics, solar power, sustainability

Robert Dunleavy had just started his sophomore year at Lehigh University when he decided he wanted to take part in a research project. He sent an email to Bryan Berger, an assistant professor of chemical and biomolecular engineering, who invited Dunleavy to his lab.

Berger and his colleagues were conducting experiments on tiny semiconductor particles called quantum dots. The optical and electronic properties of QDs make them useful in lasers, light-emitting diodes (LEDs), medical imaging, solar cells, and other applications.

Dunleavy joined Berger’s group and began working with cadmium sulfide (CdS), one of the compounds from which QDs are fabricated. The group’s goal was to find a better way of producing CdS quantum dots, which are currently made with toxic chemicals in an expensive process that requires high pressure and temperature.

Particles That Tunnel Together, Stay Together

Posted by in categories: particle physics, quantum physics

This is excellent; being able to ensuring that 2 particles can act as 1 molecule through tunneling.


Researchers have theoretically shown that in certain conditions, two particles will begin to act as if they are one molecule and undergo quantum tunneling together.

A long way from everything: The search for a Grand Unified Theory

Posted by in category: particle physics

Nice.


Albert Einstein is famous for his theories on relativity, but what of his other grand hypothesis, the unified field theory that consumed the last 30 years of his life without resolution? So will a unified theory of everything ever be realized?

Light and matter mixed in a golden nanopore room temperature plasmonic nanocavity traps

Posted by in category: particle physics

Scientists have mixed a molecule with light between gold particles, creating a new way to manipulate the physical and chemical properties of matter.

Light and matter are usually separate and have distinct properties. However, molecules of matter can emit particles of light called photons. Normally, emitted photons leave the molecule and the two do not mix again.

Now, scientists have trapped a single molecule in such a tiny space that when it emits a photon, the photon cannot escape. This produces an oscillation of energy between the molecule and the photon, creating a mixing of the properties of matter and light.

Google’s quantum computer inches nearer after landmark performance breakthrough

Posted by in categories: computing, government, nanotechnology, particle physics, quantum physics, space

Over 20 years ago, I was interviewed by a group that asked me about the future of technology. I told them due to advancements such as nanotechnology that technology will definitely go beyond laptops, networks, servers, etc.; that we would see even the threads/ fibers in our clothing be digitized. I was then given a look by the interviewers that I must have walked of the planet Mars. However, I was proven correct. And, in the recent 10 years, again I informed others how and where Quantum would change our lives forever. Again, same looks and comments.

And, lately folks have been coming out with articles that they have spoken with or interviewed QC experts. And, they in many cases added their own commentary and cherry picked people comments to discredit the efforts of Google, D-Wave, UNSW, MIT, etc. which is very misleading and negatively impacts QC efforts. When I come across such articles, I often share where and why the authors have misinformed their readers as well as negatively impacted efforts and set folks up for failure who should be trying to plan for QC in their longer term future state strategy so that they can plan for budgets, people can be brought up to date in their understanding of QC because once QC goes live on a larger scale, companies and governments will not have time to catch up because once hackers (foreign government hackers, etc.) have this technology and you’re not QC enabled then you are exposed, and your customers are exposed. The QC revolution will be costly and digital transformation in general across a large company takes years to complete so best to plan and prepare early this time for QC because it is not the same as implementing a new cloud, or ERP, or a new data center, or rationalizing a silo enterprise environment.

The recent misguided view is that we’re 30 or 50 years away from a scalable quantum chip; and that is definitely incorrect. UNSW has proven scalable QC is achievable and Google has been working on making a scalable QC chip. And, lately RMIT researchers have shared with us how they have proven method to be able to trace particles in the deepest layers of entanglement which means that we now can build QC without the need of analog technology and take full advantage of quantum properties in QC which has not been the case.

Scientists seek new physics using ORNL’s intense neutrino source

Posted by in categories: nuclear energy, particle physics

Congrats to David Dean fellow Oak Ridge researcher and leader in ORNL’s efforts on this impressive research.


OAK RIDGE, Tenn., June XX, 2016—Soon to be deployed at the Department of Energy’s Oak Ridge National Laboratory is an experiment to explore new physics associated with neutrinos. The Precision Oscillation and Spectrum Experiment, or PROSPECT, is led by Yale University and includes partners from 14 academic and governmental institutions. The DOE High Energy Physics program will support the experiment at the High Flux Isotope Reactor (HFIR), a DOE Office of Science User Facility at ORNL. The neutrino, the subject of a 2015 Nobel Prize, remains a poorly understood fundamental particle of the Standard Model of particle physics.

These electrically neutral subatomic particles are made in stars and nuclear reactors as a byproduct of radioactive decay processes. They interact with other matter via the weak force, making their detection difficult. As a result of this elusiveness, neutrinos are the subject of many interesting and challenging detection experiments, including PROSPECT.

Marrying superconductors, lasers, and Bose-Einstein condensates

Posted by in categories: particle physics, quantum physics, transportation

Nice.


Chapman University Institute for Quantum Studies (IQS) member Yutaka Shikano, Ph.D., recently had research published in Scientific Reports. Superconductors are one of the most remarkable phenomena in physics, with amazing technological implications. Some of the technologies that would not be possible without superconductivity are extremely powerful magnets that levitate trains and MRI machines used to image the human body. The reason that superconductivity arises is now understood as a fundamentally quantum mechanical effect.

The basic idea of quantum mechanics is that at the microscopic scale everything, including matter and light, has a wave property to it. Normally the wave nature is not noticeable as the waves are very small, and all the waves are out of synchronization with each other, so that their effects are not important. For this reason, to observe quantum mechanical behavior experiments generally have to be performed at a very low temperature, and at microscopic length scales.

Method for detecting quantum entanglement refined

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

This is huge! They have been able to develop a method to trace high-dimensional entanglement.

Before this point, we had a method that could trace entanglement to limited level among particles; this method allows us to detect high-dimensional entanglement and even enable us to certify whether or not the system has reached the maximum level of entanglement.

So, we are now going to finally see “real” full-scale quantum computing. This changes everything.


RMIT quantum computing researchers have developed and demonstrated a method capable of efficiently detecting high-dimensional entanglement.

Los Alamos Gets Closer To Quantum Computing

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

A walk down memory lane: I thought it would be fun to revisit an article from 1998 about Los Alamos’ announcement about their move to Quantum Computing which we found out later they expanded it to include a Quantum Network which they announced in 2009 their success in that launch. Times certainly have changed.


LOS ALAMOS, N.M., March 17, 1998 — Researchers at the Department of Energy’s Los Alamos National Laboratory have answered several key questions required to construct powerful quantum computers fundamentally different from today’s computers, they announced today at the annual meeting of the American Physical Society.

“Based on these recent experiments and theoretical work, it appears the barriers to constructing a working quantum computer will be technical, rather than fundamental to the laws of physics,” said Richard Hughes of Los Alamos’ Neutron Science and Technology Group.

Hughes also said that a quantum computer like the one Los Alamos is building, in which single ionized atoms act like a computer memory, could be capable of performing small computations within three years.

We just got better at detecting this phenomenon in quantum physics that Einstein thought was too ‘spooky’ to be real

Posted by in categories: particle physics, quantum physics

Einstein called it “spooky action at a distance.”

That’s because entanglement, a voodoo-like phenomenon in quantum physics linking particles that once interacted, seems to surpass the speed of light, violating the cosmic speed limit.

Because of this, it doesn’t fit in with Einstein’s theory of relativity, so he concluded that it was too ludicrous to be real.
