Quantum computing advance locates neutral atoms

Posted by in categories: computing, particle physics

For any computer, being able to manipulate information is essential, but for quantum computing, singling out one data location without influencing any of the surrounding locations is difficult. Now, a team of Penn State physicists has a method for addressing individual neutral atoms without changing surrounding atoms.

“There are a set of things that we have to have to do quantum computing,” said David S. Weiss, professor of physics. “We are trying to step down that list and meet the various criteria. Addressability is one step.”

Quantum computers are constructed and operate in completely different ways from the conventional digital computers used today. While conventional computers store information in bits, 1‘s and 0’s, quantum computers store information in qubits. Because of a strange aspect of quantum mechanics called superposition, a qubit can be in both its 0 and 1 state at the same time. The methods of encoding information onto , ions or Josephson junctions—electronic devices used in precise measurement, to create quantum computers—are currently the subject of much research. Along with superposition, quantum computers will also take advantage of the quantum mechanical phenomena of entanglement, which can create a mutually dependent group of qubits that must be considered as a whole rather than individually.

Scientists have finally discovered massless particles, and they could revolutionise electronics

Posted by in categories: electronics, particle physics

After 85 years of searching, researchers have confirmed the existence of a massless particle called the Weyl fermion for the first time ever. With the unique ability to behave as both matter and anti-matter inside a crystal, this strange particle can create electrons that have no mass.

Discovery Of Massless Weyl Fermion Particle Could Revolutionize Electronics

Posted by in categories: electronics, particle physics

Two separate teams of researchers have found evidence for a theorized type of massless particle known as a “Weyl fermion.” The discovery was made by scientists at Princeton University in New Jersey and the Massachusetts Institute of Technology, and could herald a whole new age of better electronics.

Strings Are Dead

Posted by in categories: anti-gravity, cosmology, defense, general relativity, gravity, innovation, particle physics, philosophy, physics, policy, quantum physics, science, space travel

In 2014, I submitted my paper “A Universal Approach to Forces” to the journal Foundations of Physics. The 1999 Noble Laureate, Prof. Gerardus ‘t Hooft, editor of this journal, had suggested that I submit this paper to the journal Physics Essays.

My previous 2009 submission “Gravitational acceleration without mass and noninertia fields” to Physics Essays, had taken 1.5 years to review and be accepted. Therefore, I decided against Prof. Gerardus ‘t Hooft’s recommendation as I estimated that the entire 6 papers (now published as Super Physics for Super Technologies) would take up to 10 years and/or $20,000 to publish in peer reviewed journals.

Prof. Gerardus ‘t Hooft had brought up something interesting in his 2008 paper “A locally finite model for gravity” that “… absence of matter now no longer guarantees local flatness…” meaning that accelerations can be present in spacetime without the presence of mass. Wow! Isn’t this a precursor to propulsion physics, or the ability to modify spacetime without the use of mass?

As far as I could determine, he didn’t pursue this from the perspective of propulsion physics. A year earlier in 2007, I had just discovered the massless formula for gravitational acceleration g=τc^2, published in the Physics Essays paper referred above. In effect, g=τc^2 was the mathematical solution to Prof. Gerardus ‘t Hooft’s “… absence of matter now no longer guarantees local flatness…”
