How quantum dots can revolutionize solar energy

Posted by in categories: particle physics, quantum physics, solar power, sustainability

There’s a new way to harness the power of the sun and it may just revolutionize how we approach solar energy. The development is called quantum dots and it consists of tiny semiconductor particles only a few nanometers in size.

This is according to a report by Fagen Wasanni published on Saturday.

“Quantum dots have unique properties that make them ideal for use in solar cells. Their small size allows them to absorb light from a wide range of wavelengths, including those that traditional solar cells cannot capture. This means that quantum dot-based solar cells can potentially convert more sunlight into electricity, significantly increasing their efficiency,” states the report.

Fluxonium Qubit Retains Information For 1.43 Milliseconds — 10x Longer Than Before

Posted by in categories: computing, information science, quantum physics

Superconducting quantum technology has long promised to bridge the divide between existing electronic devices and the delicate quantum landscape beyond. Unfortunately progress in making critical processes stable has stagnated over the past decade.

Now a significant step forward has finally been realized, with researchers from the University of Maryland making superconducting qubits that last 10 times longer than before.

What makes qubits so useful in computing is the fact their quantum properties entangle in ways that are mathematically handy for making short work of certain complex algorithms, taking moments to solve select problems that would take other technology decades or more.

European researchers design a rubber block that can count to ten

Posted by in categories: computing, mathematics, quantum physics

Physicist Lennard Kwakernaak finds the “complexity of simple things” intriguing, and it is a tough ask to make an inanimate object count.

A collaboration between researchers at Leiden University and AMOLF in Amsterdam has yielded a new metamaterial, a rubber block that can count. The researchers are calling it a Beam Counter and it is pretty nifty.

A New Kind of Quantum Computer Could Be Built on The Strange Physics of Sound Waves

Posted by in categories: computing, particle physics, quantum physics

When you turn on a lamp to brighten a room, you are experiencing light energy transmitted as photons, which are small, discrete quantum packets of energy.

These photons must obey the sometimes strange laws of quantum mechanics, which, for instance, dictate that photons are indivisible, but at the same time, allow a photon to be in two places at once.

Quantum neural networks: An easier way to learn quantum processes

Posted by in categories: quantum physics, robotics/AI

EPFL scientists show that even a few simple examples are enough for a quantum machine-learning model, the “quantum neural networks,” to learn and predict the behavior of quantum systems, bringing us closer to a new era of quantum computing.

Imagine a world where computers can unravel the mysteries of , enabling us to study the behavior of complex materials or simulate the intricate dynamics of molecules with unprecedented accuracy.

Thanks to a pioneering study led by Professor Zoe Holmes and her team at EPFL, we are now closer to that becoming a reality. Working with researchers at Caltech, the Free University of Berlin, and the Los Alamos National Laboratory, they have found a new way to teach a quantum computer how to understand and predict the behavior of quantum systems. The research has been published in Nature Communications.

Quantum physicists design unconditionally secure system for digital payments

Posted by in categories: cybercrime/malcode, quantum physics

Have you ever been compelled to enter sensitive payment data on the website of an unknown merchant? Would you be willing to consign your credit card data or passwords to untrustworthy hands? Scientists from the University of Vienna have now designed an unconditionally secure system for shopping in such settings, combining modern cryptographic techniques with the fundamental properties of quantum light. The demonstration of such “quantum-digital payments” in a realistic environment has been published in Nature Communications.

Digital payments have replaced physical banknotes in many aspects of our daily lives. Similar to banknotes, they should be easy to use, unique, tamper-resistant and untraceable, but additionally withstand digital attackers and data breaches.

In today’s ecosystem, customers’ sensitive data is substituted by sequences of random numbers, and the uniqueness of each is secured by a classical cryptographic method or code. However, adversaries and merchants with powerful computational resources can crack these codes and recover the customers’ private data, and for example, make payments in their name.
