The new particle tested as a possible Higgs boson[edit]

Posted by in categories: particle physics, quantum physics

The Higgs boson is an elementary particle in the Standard Model of particle physics, produced by the quantum excitation of the Higgs field,[8][9] one of the fields in particle physics theory.[9] It is named after physicist Peter Higgs, who in 1964, along with five other scientists, proposed the Higgs mechanism to explain why particles have mass. This mechanism implies the existence of the Higgs boson. The boson’s existence was confirmed in 2012 by the ATLAS and CMS collaborations based on collisions in the LHC at CERN.

On December 10, 2013, two of the physicists, Peter Higgs and François Englert, were awarded the Nobel Prize in Physics for their theoretical predictions. Although Higgs’s name has come to be associated with this theory (the Higgs mechanism), several researchers between about 1960 and 1972 independently developed different parts of it.

In mainstream media the Higgs boson has often been called the “God particle”, from a 1993 book on the topic,[10] although the nickname is strongly disliked by many physicists, including Higgs himself, who regard it as sensationalism.[11][12].

New laser technique images quantum world in a trillionth of a second

Posted by in categories: biotech/medical, quantum physics

For the first time, researchers have been able to record, frame-by-frame, how an electron interacts with certain atomic vibrations in a solid. The technique captures a process that commonly causes electrical resistance in materials while, in others, can cause the exact opposite—the absence of resistance, or superconductivity.

“The way electrons interact with each other and their microscopic environment determines the properties of all solids,” said MengXing Na, a University of British Columbia (UBC) Ph.D. student and co-lead author of the study, published last week in Science. “Once we identify the dominant microscopic interactions that define a material’s properties, we can find ways to ‘turn up’ or ‘down’ the interaction to elicit useful electronic properties.”

Controlling these interactions is important for the technological exploitation of quantum materials, including superconductors, which are used in MRI machines, high-speed magnetic levitation trains, and could one day revolutionize how energy is transported.

Quantum teleportation used to send 3D information for the first time

Posted by in category: quantum physics

O.o.


Quantum teleportation has only ever been performed with qubits, which have two dimensions. Now it’s been done with a 3D qutrit for the first time.

Quantum field theory: “An unholy crossbreed between quantum physics in a bad mood and every button you never push on a calculator”

Posted by in categories: particle physics, quantum physics

Quantum field theory doesn’t get much coverage in popular science and if you open any textbook on the subject you’ll see why. It looks like an unholy crossbreed between quantum physics in a bad mood and every button you never push on a calculator. The idea of summarising it in 1,500 words or less for this article sounded daunting at first (it took a whole chapter to cover it in my recent book) but then again if I really did have to present it to a jury of aliens I wouldn’t have a choice.

Therefore, your honour, I request that you give me five minutes of your intergalactic attention. My presentation may not feature Jason Statham roundhouse kicking a shark in the eyeball, but I am going to try and justify the continued existence of the human race. Here goes…

In surprise breakthrough, scientists create quantum states in everyday electronics

Posted by in categories: computing, engineering, mobile phones, particle physics, quantum physics, transportation

After decades of miniaturization, the electronic components we’ve relied on for computers and modern technologies are now starting to reach fundamental limits. Faced with this challenge, engineers and scientists around the world are turning toward a radically new paradigm: quantum information technologies.

Quantum technology, which harnesses the strange rules that govern particles at the , is normally thought of as much too delicate to coexist with the electronics we use every day in phones, laptops and cars. However, scientists with the University of Chicago’s Pritzker School of Molecular Engineering announced a significant breakthrough: Quantum states can be integrated and controlled in commonly used made from silicon carbide.

“The ability to create and control high-performance quantum bits in commercial electronics was a surprise,” said lead investigator David Awschalom, the Liew Family Professor in Molecular Engineering at UChicago and a pioneer in quantum technology. “These discoveries have changed the way we think about developing quantum technologies—perhaps we can find a way to use today’s electronics to build quantum devices.”

Liquid flow is influenced by a quantum effect in water

Posted by in categories: biotech/medical, quantum physics

Researchers at EPFL have discovered that the viscosity of solutions of electrically charged polymers dissolved in water is influenced by a quantum effect. This tiny quantum effect influences the way water molecules interact with one another. Yet, it can lead to drastic changes in large-scale observations. This effect could change the way scientists understand the properties and behavior of solutions of biomolecules in water, and lead to a better understanding of biological systems.

Water is the basis of all life on earth. Its structure is simple—two bound to one —yet its behavior is unique among liquids, and scientists still do not fully understand the origins of its distinctive properties.

When charged polymers are dissolved in water the aqueous becomes more viscous than expected. This high viscosity is used by nature in the human body. The lubricating and shock-absorbing properties of the synovial fluid—a solution of water and charged biopolymers—is what allows us to bend, stretch and compress our joints over our entire lives without damage.

Using Quantum Mechanics to Trigger Atomic Fusion

Posted by in categories: nuclear energy, particle physics, quantum physics, space

Nuclear physics usually involves high energies, as illustrated by experiments to master controlled nuclear fusion. One of the problems is how to overcome the strong electrical repulsion between atomic nuclei which requires high energies to make them fuse. But fusion could be initiated at lower energies with electromagnetic fields that are generated, for example, by state-of-the-art free electron lasers emitting X-ray light. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) describe how this could be done in the journal Physical Review C.

During nuclear fusion two atomic nuclei fuse into one new nucleus. In the lab this can be done by particle accelerators, when researchers use fusion reactions to create fast free neutrons for other experiments. On a much larger scale, the idea is to implement controlled fusion of light nuclei to generate power – with the sun acting as the model: its energy is the product of a series of fusion reactions that take place in its interior.

For many years, scientists have been working on strategies for generating power from fusion energy. “On the one hand we are looking at a practically limitless source of power. On the other hand, there are all the many technological hurdles that we want to help surmount through our work,” says Professor Ralf Schützhold, Director of the Department of Theoretical Physics at HZDR, describing the motivation for his research.

From mind control, brainwashing and monsters — theories claim Stranger Things happened in REAL LIFE in a secret government project

Posted by in categories: computing, food, government, mobile phones, neuroscience, quantum physics, time travel

In my humble opinion, this was very real but is still based on science. But quantum mechanics would democratize this technology rather than needing a human interface. I think in the right hands and doing good it comes essentially do so much even materializing water or food endlessly using psionic abilities. Really quantum mechanics could lead to even materializing a cup of coffee from a computer. This is probably the most groundbreaking knowledge because quantum mechanics can prove that this is real. There are still ethical problems with this technology but the possibilities make this essentially a cheaper form of a replicator than essentially a Higgs boson one may be using a lot less energy. If it was fully understood it could allow for real psionic abilities for everyone maybe using a device perhaps even with a limiter for safety or even air-gapped so it is just on a smartphone. One day you could essentially just press a button on a smartphone and a cup of coffee would materialize or your favorite beverage, not just a uber or teleportation but essentially real materializing which some say that has been used possibly since the founding of the planet earth based on mythology seen from all over the planet earth.


SPINE-chilling stories about the sinister goings-on at Camp Hero air force base in Montauk have long been the stuff of local legend.

Since the Seventies, tall tales have surrounded the derelict facility in Long Island, New York.
