Mathematical Breakthrough Makes It Easier to Explore Quantum Entanglement

Posted by in categories: information science, mathematics, particle physics, quantum physics

Updated mathematical techniques that can distinguish between two types of ‘non-Gaussian curve’ could make it easier for researchers to study the nature of quantum entanglement.

Quantum entanglement is perhaps one of the most intriguing phenomena known to physics. It describes how the fates of multiple particles can become entwined, even when separated by vast distances. Importantly, the probability distributions needed to define the quantum states of these particles deviate from the bell-shaped, or ‘Gaussian’ curves which underly many natural processes. Non-Gaussian curves don’t apply to quantum systems alone, however. They can also be composed of mixtures of regular Gaussian curves, producing difficulties for physicists studying quantum entanglement. In new research published in EPJ D, Shao-Hua Xiang and colleagues at Huaihua University in China propose a solution to this problem. They suggest an updated set of equations that allows physicists to easily check whether or not a non-Gaussian state is genuinely quantum.

As physicists make more discoveries about the nature of quantum entanglement, they are rapidly making progress towards advanced applications in the fields of quantum communication and computation. The approach taken in this study could prove to speed up the pace of these advances. Xiang and colleagues acknowledge that while all previous efforts to distinguish between both types of non-Gaussian curve have had some success, their choices of Gaussian curves as a starting point have so far meant that no one approach has yet proven to be completely effective. Based on the argument that there can’t be any truly reliable Gaussian reference for any genuinely quantum non-Gaussian state, the researchers present a new theoretical framework.

Adult-born neurons grow more than their infancy-born counterparts

Posted by in category: neuroscience

Summary: Neurons created as a result of adult neurogenesis mature for longer and grow larger than those created during infancy. Findings suggest adult-born neurons may have a more powerful function than those created during infancy and may play a critical role in neuroplasticity.

Adult-born neurons keep growing and contributing to brain flexibility long after neurogenesis declines, according to research in rats published in Journal of Neuroscience.

Scientists Have Demonstrated Quantum Entanglement on a Tiny Satellite Orbiting Earth

Posted by in categories: internet, particle physics, quantum physics, space

In the strange field of quantum physics, quantum entanglement – what Einstein called “spooky action at a distance” – stands out as one of the most intriguing phenomena. And now scientists just managed to successfully demonstrate it again, this time onboard a CubeSat satellite orbiting Earth.

Quantum entanglement is where two particles become inextricably linked across a distance, so that one serves as an indicator of the other in a certain aspect. That unbreakable link might one day form the basis of a super-fast, super-secure quantum internet.

While a quantum internet is still some way off, if we want to make it work, it’s going to require something other than optical fibres.

A new scout helicopter will replace half the Army’s Apache fleet

Posted by in categories: futurism, transportation

Undeterred by decades of failure, the U.S. Army is trying again to acquire a new scout helicopter. The new rotorcraft is supposed to restore the dedicated aerial scout mission the Army gave up when in 2017 it retired its roughly 300 Bell OH-58D Kiowa Warrior copters.

And here’s a surprise. The new Future Attack Reconnaissance Aircraft also will replace half of the ground-combat branch’s 700 Boeing AH-64 Apache attack helicopters.

Lockheed Martin’s New F-21 Fighter on offer to India has F-22 and F-35 ‘DNA’

Posted by in categories: biotech/medical, military

New Delhi could select its new fighter in 2019. If it picks the F-21 and opts to keep Lockheed’s designation for the type, it rightfully could claim to be the first operator of a brand-new fighter.

Lockheed Martin in mid-February 2019 offered to sell India a new fighter the company calls the “F-21.”

Only it doesn’t look like a new fighter at all. The F-21 looks like an F-16.

ChipScope – a new approach to optical microscopy

Posted by in category: electronics

For half a millennium, people have tried to enhance human vision by technical means. While the human eye is capable of recognizing features over a wide range of size, it reaches its limits when peering at objects over giant distances or in the micro- and nanoworld. Researchers of the EU funded project ChipScope are now developing a completely new strategy towards optical microscopy.

The conventional light microscope, still standard equipment in laboratories, underlies the fundamental laws of optics. Thus, resolution is limited by diffraction to the so called Abbe limit’ – structural features smaller than a minimum of 200 nm cannot be resolved by this kind of microscope.

So far, all technologies for going beyond the Abbe limit rely on complex setups, with bulky components and advanced laboratory infrastructure. Even a conventional light microscope, in most configurations, is not suitable as a mobile gadget to do research out in the field or in . In the ChipScope project funded by the EU, a completely new strategy towards optical microscopy is explored. In classical the analyzed sample area is illuminated simultaneously, collecting the light which is scattered from each point with an area-selective detector, e.g. the human eye or the sensor of a camera.
