Tachyon physics with trapped ions

Posted by in categories: particle physics, quantum physics

It has been predicted that particles with imaginary mass, called tachyons, would be able to travel faster than the speed of light. There has not been any experimental evidence for tachyons occurring naturally. Here, we propose how to experimentally simulate Dirac tachyons with trapped ions. Quantum measurement on a Dirac particle simulated by a trapped ion causes it to have an imaginary mass so that it may travel faster than the effective speed of light. We show that a Dirac tachyon must have spinor-motion correlation in order to be superluminal. We also show that it exhibits significantly more Klein tunneling than a normal Dirac particle. We provide numerical simulations of realistic ion systems and show that our scheme is feasible with current technology.

“We will find new things everywhere we look.” –Hunter S. Thompson

At the rate of 21st century technological innovation, each year brings new breakthroughs across industries. Advances in quantum computers, human genome sequencing for under $1,000, lab-grown meat, harnessing our body’s microbes as drugs, and bionic eye implants that give vision to the blind —the list is long.

Cybersecurity Challenges, Opportunities Discussed at Dedication of Expanded National Cybersecurity Center of Excellence

Posted by in categories: business, cybercrime/malcode, quantum physics

If Russia, China, etc. upgrades their infrastructure to Quantum before US and it’s does; today’s breaches will not even compare to this scenario.


The push to bring more technology-related businesses to the state has officials hoping for long-term growth over places like Fairfax County, Va., where the federal government has already made substantial technological investment.

After the ceremony, an expert panel discussed some of the opportunities and challenges facing information infrastructure, the importance of collaboration between the public and private sectors, and how to increase consumers’ cybersecurity confidence.

Quantum Levitation

Posted by in categories: materials, quantum physics, transportation

Researchers at the school of physics and astronomy at Tel Aviv University have created a track around which a superconductor (a material that is extremely efficient at transmitting electricity) can float, thanks to the phenomenon of “quantum levitation “.

This levitation effect is explained by the Meissner effect, which describes how, when a material makes the transition from its normal to its superconducting state, it actively excludes magnetic fields from its interior, leaving only a thin layer on its surface.

When a material is in its superconducting state — which involves very low temperatures — it is strongly diamagnetic. This means that when a magnetic field is externally applied, it will create an equally opposing magnetic field, locking it in place.

Chiral magnetic effect generates quantum current

Posted by in categories: computing, materials, quantum physics

Another step forward for Quantum — The Quantum Current. US Dept. of Energy has a new method to generate very low-resistance electric (Quantum) current which will improve our methods for energy, quantum computing, and medical imaging, and possibly even a new mechanism for inducing superconductivity—the ability of some materials (zirconium pentatelluride) to carry current with no energy loss.

Google’s AI Technology Will Transform Life As We Know It

Posted by in categories: quantum physics, robotics/AI

Me and one of my friends on LinkedIn both knew it was only a matter of time that AI & Quantum together would be announced. And, Google with D-Wave indeed would be leading this charge. BTW — once this pairing of technologies is done; get ready for some amazing AI technology including robotics to come out.


But there may not be any competitors for a while if Google’s “Ace of Spades” newbie performs as they predict. According to Hartmut Neven, head of its Quantum Al Lab, this baby can run:

“We found that for problem instances involving nearly 1,000 binary variables, quantum annealing significantly outperforms its classical counterpart, simulated annealing. It is more than 10 to the power of 8 times faster than simulated annealing running on a single core.”

It seems life really does have a vital spark: quantum mechanics

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

We all have “Quantum Spark”.


For centuries philosophers have grappled with the question of what makes life, and thanks to the science of quantum mechanics we might just have the answer, writes Johnjoe McFadden.

What is life? Why is the stuff of life — flesh — so different from inanimate material? Does life obey the same laws as the inanimate world? And what happens when we die?

Artificial Life in Quantum Technologies

Posted by in categories: bioengineering, evolution, quantum physics

We develop a quantum information protocol that models the biological behaviours of individuals living in a natural selection scenario. The artificially engineered evolution of the quantum living units shows the fundamental features of life in a common environment, such as self-replication, mutation, interaction of individuals, and death. We propose how to mimic these bio-inspired features in a quantum-mechanical formalism, which allows for an experimental implementation achievable with current quantum platforms. This study paves the way for the realization of artificial life and embodied evolution with quantum technologies.

Quantum state of molecular ion measured live, non-destructively

Posted by in categories: energy, quantum physics

A non-destructive Quantum State.


The interaction of thermal energy from the environment with motional degrees of freedom is well known and often referred to as Brownian motion (also thermal motion). But in the case of polar molecules, the internal degrees of freedom — in particular the rotational quantum state — are also influenced by the thermal radiation. So far, the detection of the rotational state was only possible by destroying the molecule. However, a German research group has now demonstrated the first implementation of a non-destructive state detection technique for molecular ions.
