Researchers create quantum chip 1,000 times smaller than current setups

Posted by in categories: computing, information science, mobile phones, quantum physics, security

Researchers at Nanyang Technological University, Singapore (NTU Singapore) have developed a quantum communication chip that is 1,000 times smaller than current quantum setups, but offers the same superior security quantum technology is known for.

Most leading security standards used in secure communication methods—from withdrawing cash from the ATM to purchasing goods online on the smartphone—does not leverage quantum technology. The electronic transmission of the personal identification number (PIN) or password can be intercepted, posing a .

Roughly three millimeters in size, the tiny chip uses quantum communication algorithms to provide enhanced security compared to existing standards. It does this by integrating passwords within the information that is being delivered, forming a secure quantum key. After the information is received, it is destroyed along with the key, making it an extremely secure form of communication.

A Simple Filter Turns Blue OLED Light Into White

Posted by in categories: computing, mobile phones

Compared to regular blue OLED these converted white OLED last 30 times longer.


Organic light-emitting diodes (OLEDs) have come a long way since the first working device was reported three decades ago. Prized for their dark blacks, crisp image reproduction, and power efficiency, today’s OLEDs dominate the screens of Android phones and LG televisions. They may take over iPhones as early as next year.

And because OLEDs are cheap and easy to make, we ought to also use them to make white light for general illumination, says Konstantinos Daskalakis, a post-doctoral researcher at Aalto University in Finland.

How India’s farmers are using technology to feed more than a billion people

Posted by in categories: biotech/medical, food, internet, mobile phones

Hundreds of millions of people in India depend on farming for their livelihoods, but many of them struggle with losing crops to disease, getting them to market or achieving the right price when they do. Several startups are trying to change that.

Piggybacking on India’s mobile boom, these companies are using smartphones and the internet to help farmers grow, harvest and sell their crops more efficiently. India is self-sufficient in food staples, but faces a constant challenge to feed its population of 1.3 billion and rising. The country accounts for a quarter of the world’s hungry people and is home to over 190 million undernourished people, according to the latest estimates by the United Nations.

“There is a lot of financing and talent which is coming in this space,” says Rikin Gandhi, co-founder and executive director of Digital Green, a social enterprise that began as a research project backed by Microsoft ( MSFT ).

Elon Musk’s Neuralink unveils device to connect your brain to a smartphone

Posted by in categories: Elon Musk, mobile phones, robotics/AI

Neuralink seeks to build a brain-machine interface that would connect human brains with computers. No tests have been performed in humans, but the company hopes to obtain FDA approval and begin human trials in 2020. Musk said the technology essentially provides humans the option of “merging with AI.”

Directed-energy weapon (DEW) full documentary

Posted by in categories: drones, military, mobile phones, particle physics

A directed-energy weapon (DEW) emits highly focused energy, transferring that energy to a target to damage it.

Potential applications of this technology include anti-personnel weapon systems, potential missile defense system, and the disabling of lightly armored vehicles such as cars, drones, watercraft, and electronic devices such as mobile phones.

This “Quantum Battery” Never Loses Its Charge

Posted by in categories: mobile phones, quantum physics

A team of scientists from the universities of Alberta and Toronto have laid out the blueprints for a “quantum battery” that never loses its charge.

To be clear, this battery doesn’t exist yet — but if they figure out how to build it, it could be a revolutionary breakthrough in energy storage.

“The batteries that we are more familiar with — like the lithium-ion battery that powers your smartphone — rely on classical electrochemical principles, whereas quantum batteries rely solely on quantum mechanics,” University of Alberta chemist Gabriel Hanna said in a statement.

Pushing quantum photonics

Posted by in categories: computing, mobile phones, quantum physics

Quantum computers use the fundamentals of quantum mechanics to potentially speed up the process of solving complex computations. Suppose you need to perform the task of searching for a specific number in a phone book. A classical computer will search each line of the phone book until it finds a match. A quantum computer could search the entire phone book at the same time by assessing each line simultaneously and return a result much faster.

New supercomputer simulations explore magnetic reconnection and make a surprising discovery

Posted by in categories: cosmology, mobile phones, supercomputing

Magnetic reconnection, a process in which magnetic field lines tear and come back together, releasing large amounts of kinetic energy, occurs throughout the universe. The process gives rise to auroras, solar flares and geomagnetic storms that can disrupt cell phone service and electric grids on Earth. A major challenge in the study of magnetic reconnection, however, is bridging the gap between these large-scale astrophysical scenarios and small-scale experiments that can be done in a lab.

Researchers have now overcome this barrier through a combination of clever experiments and cutting-edge simulations. In doing so, they have uncovered a previously unknown role for a universal process called the “Biermann battery effect,” which turns out to impact magnetic in unexpected ways.

The Biermann battery effect, a possible seed for the magnetic fields pervading our universe, generates an electric current that produces these fields. The surprise findings, made through , show the effect can play a significant role in the reconnection occurring when the Earth’s magnetosphere interacts with astrophysical plasmas. The effect first generates lines, but then reverses roles and cuts them like scissors slicing a rubber band. The sliced fields then reconnect away from the original reconnection point.
