Strange warping geometry helps to push scientific boundaries
Posted by Quinn Sena in categories: computing, mathematics, particle physics, space, transportation
Atomic interactions in everyday solids and liquids are so complex that some of these materials’ properties continue to elude physicists’ understanding. Solving the problems mathematically is beyond the capabilities of modern computers, so scientists at Princeton University have turned to an unusual branch of geometry instead.
Researchers led by Andrew Houck, a professor of electrical engineering, have built an electronic array on a microchip that simulates particle interactions in a hyperbolic plane, a geometric surface in which space curves away from itself at every point. A hyperbolic plane is difficult to envision—the artist M.C. Escher used hyperbolic geometry in many of his mind-bending pieces—but is perfect for answering questions about particle interactions and other challenging mathematical questions.
The research team used superconducting circuits to create a lattice that functions as a hyperbolic space. When the researchers introduce photons into the lattice, they can answer a wide range of difficult questions by observing the photons’ interactions in simulated hyperbolic space.

Secure quantum communications in the microwave range for the first time
Posted by Quinn Sena in categories: computing, particle physics, quantum physics
Mikel Sanz, of the Physical Chemistry Department of UPV/EHU, leads the theoretical group for an experiment published by the prestigious journal, Nature Communications. The experiment has managed to prepare a remote quantum state; i.e., absolutely secure communication was established with another, physically separated quantum computer for the first time in the microwave regime. This new technology may bring about a revolution in the next few years.
Within the greater European project of the Quantum Flagship, spearheaded by Mikel Sanz—researcher of the QUTIS Group of the UPV/EHU Physical Chemistry Department—an experiment has been conducted in collaboration with German and Japanese researchers who have managed to develop a protocol for preparing a remote quantum state while conducting communication in the microwave regime, “which is the frequency at which all quantum computers operate. This is the first time the possibility of doing so in this range has been examined, which may bring about a revolution in the next few years in the field of secure quantum communication and quantum microwave radars,” lead researcher in this project Mikel Sanz observes.
The preparation of a remote quantum state (known as remote state preparation) is based on the phenomenon of quantum entanglement, where sets of entangled particles lose their individuality and behave as single entities, even when spatially separated. “Thus, if two computers share this quantum correlation, performing operations on only one of them can affect the other. Absolutely secure communication can be achieved,” Sanz explains.

Simulation shows nuclear pasta 10 billion times harder to break than steel
Posted by Quinn Sena in categories: computing, particle physics
A trio of researchers affiliated with several institutions in the U.S. and Canada has found evidence that suggests nuclear material beneath the surface of neutron stars may be the strongest material in the universe. In their paper published in the journal Physical Review Letters, M. E. Caplan, A. Schneider, and C. J. Horowitz describe their neutron star simulation and what it showed.
Prior research has shown that when stars reach a certain age, they explode and collapse into a mass of neutrons; hence the name neutron star. And because they lose their neutrinos, neutron stars become extremely densely packed. Prior research has also found evidence that suggests the surface of such stars is so dense that the material would be incredibly strong. In this new effort, the researchers report evidence suggesting that the material just below the surface is even stronger.
Astrophysicists have theorized that as a neutron star settles into its new configuration, densely packed neutrons are pushed and pulled in different ways, resulting in formation of various shapes below the surface. Many of the theorized shapes take on the names of pasta, because of the similarities. Some have been named gnocchi, for example, others spaghetti or lasagna. Caplan, Schneider and Horowitz wondered about the density of these formations—would they be denser and thus stronger even than material on the crust? To find out, they created some computer simulations.

Honeywell Trapped Ion Quantum Computer
Posted by Quinn Sena in categories: computing, quantum physics
Honeywell Quantum Solutions has demonstrated record-breaking high fidelity quantum operations on their trapped-ion qubits. It is a major step towards producing the world’s most powerful quantum computer. Honeywell targets an operational trapped ion quantum computer by the end of 2019.
Currently the leading trapped ion quantum computer is by the startup IonQ. There are commercial quantum annealing systems from D-Wave Systems with 2000 qubits. There are superconducting quantum computers with 16–72 qubits from Google, IBM, Intel and Rigetti Systems.

Tiny granules can help bring clean and abundant fusion power to Earth
Posted by Quinn Sena in categories: computing, physics, space travel
Beryllium, a hard, silvery metal long used in X-ray machines and spacecraft, is finding a new role in the quest to bring the power that drives the sun and stars to Earth. Beryllium is one of the two main materials used for the wall in ITER, a multinational fusion facility under construction in France to demonstrate the practicality of fusion power. Now, physicists from the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and General Atomics have concluded that injecting tiny beryllium pellets into ITER could help stabilize the plasma that fuels fusion reactions.
Experiments and computer simulations found that the injected granules help create conditions in the plasma that could trigger small eruptions called edge-localized modes (ELMs). If triggered frequently enough, the tiny ELMs prevent giant eruptions that could halt fusion reactions and damage the ITER facility.
Scientists around the world are seeking to replicate fusion on Earth for a virtually inexhaustible supply of power to generate electricity. The process involves plasma, a very hot soup of free-floating electrons and atomic nuclei, or ions. The merging of the nuclei releases a tremendous amount of energy.

Quantum Particles Found Exhibiting Immortality Through “Infinite Decay And Rebirth”

We know that the rule “nothing lasts forever” holds true for everything. But the world of quantum particles doesn’t always seem to follow the rules.
In the latest findings, scientists have observed that quasiparticles in quantum systems could be virtually immortal. These particles can regenerate themselves after they have decayed — and this can have a significant impact on the future of quantum computing and humanity itself.

Voracious Black Holes Could Feed Alien Life on Rogue Worlds
Posted by Quinn Sena in categories: alien life, computing
O.o…
Black holes are engines of destruction on a cosmic scale, but they may also be the bringers of life. New research on supermassive black holes suggests that the radiation they emit during feeding frenzies can create biomolecular building blocks and even power photosynthesis.
The upshot? Far more worlds roaming the Milky Way and beyond could be suitable to life, the researchers speculated.
