Researchers propose a smaller, more noise-tolerant quantum factoring circuit for cryptography

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

The most recent email you sent was likely encrypted using a tried-and-true method that relies on the idea that even the fastest computer would be unable to efficiently break a gigantic number into factors.

Quantum computers, on the other hand, promise to rapidly crack complex cryptographic systems that a classical computer might never be able to unravel. This promise is based on a quantum factoring proposed in 1994 by Peter Shor, who is now a professor at MIT.

But while researchers have taken great strides in the last 30 years, scientists have yet to build a quantum computer powerful enough to run Shor’s algorithm.

Scientists Identify New Class of Semiconductor Nanocrystals

Posted by in categories: chemistry, computing

U.S. Naval Research Laboratory (NRL) scientists confirm the identification of a new class of semiconductor nanocrystals with bright ground-state excitons, a significant advancement in the field of optoelectronics, in an article published in the American Chemical Society (ACS) journal ACS Nano.

The groundbreaking theoretical research could revolutionize the development of highly efficient light-emitting devices and other technologies.

Generally, the lowest-energy exciton in nanocrystals is poorly emitting, earning the name “dark” exciton. Because it slows the emission of light, the dark exciton limits the performance of nanocrystal-based devices like lasers or light-emitting diodes (LEDs). Scientists have long sought to overcome the dark exciton.

Quantum information theorists are shedding light on entanglement, one of the spooky mysteries of quantum mechanics

Posted by in categories: computing, quantum physics

But despite creating all these breakthrough technologies, physicists and philosophers who study quantum mechanics still haven’t come up with the answers to some big questions raised by the field’s founders. Given recent developments in quantum information science, researchers like me are using quantum information theory to explore new ways of thinking about these unanswered foundational questions. And one direction we’re looking into relates Albert Einstein’s relativity principle to the qubit.

Quantum computers

Quantum information science focuses on building quantum computers based on the quantum “bit” of information, or qubit. The qubit is historically grounded in the discoveries of physicists Max Planck and Einstein. They instigated the development of quantum mechanics in 1900 and 1905, respectively, when they discovered that light exists in discrete, or “quantum,” bundles of energy.

Publisher retracts 350 papers at once

Posted by in categories: computing, engineering, physics

IOP Publishing has retracted a total of 350 papers from two different 2021 conference proceedings because an “investigation has uncovered evidence of systematic manipulation of the publication process and considerable citation manipulation.”

The case is just the latest involving the discovery of papers full of gibberish – aka “tortured phrases” – thanks to the work of Guillaume Cabanac, a computer scientist at the University of Toulouse, Cyril Labbé, of University Grenoble-Alpes and Alexander Magazinov, of Skoltech, in Moscow. The tool detects papers that contain phrases that appear to have been translated from English into another language, and then back into English, likely with the involvement of paper-generating software.

The papers were in the Journal of Physics: Conference Series (232 articles), and IOP Conference Series: Materials Science and Engineering (118 articles), plus four editorials.
