An asteroid is approaching, so I invited one of Earth’s defenders to dinner

Posted by in categories: asteroid/comet impacts, existential risks, satellites

Near-Earth Asteroid 99942 Apophis will be visible on Sunday. Some say it could ultimately destroy satellites and spaceships. The creators of the Unistellar eVscope telescope are trying to marshal our defense.

South Africa Moves to Manufacture, Commercialize Hydrogen Fuel Cell Technology

Posted by in categories: energy, government

After over a decade of research and development around hydrogen fuel technology, President Cyril Ramaphosa says South Africa is now ready to manufacture and commercialise hydrogen fuels technology.

The President said this when he responded to a debate on the State of the Nation Address in Parliament on Thursday.

For more than a decade, government has been working with various partners, including the private sector and academia, to develop hydrogen fuel cell and lithium battery storage technologies.

Qudits and High-Dimensional Quantum Computing

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

10 November 2020


Qudit is a multi-level computational unit alternative to the conventional 2-level qubit. Compared to qubit, qudit provides a larger state space to store and process information, and thus can provide reduction of the circuit complexity, simplification of the experimental setup and enhancement of the algorithm efficiency. This review provides an overview of qudit-based quantum computing covering a variety of topics ranging from circuit building, algorithm design, to experimental methods. We first discuss the qudit gate universality and a variety of qudit gates including the pi/8 gate, the SWAP gate, and the multi-level controlled-gate. We then present the qudit version of several representative quantum algorithms including the Deutsch-Jozsa algorithm, the quantum Fourier transform, and the phase estimation algorithm.

Coding for Qubits: How to Program in Quantum Computer Assembly Language

Posted by in categories: computing, quantum physics

Sandia Labs pioneers Just Another Quantum Assembly Language (.


Quantum computing arguably isn’t quite full-fledged computing till there’s quantum software as well as hardware. One open-source quantum computer project at Sandia National Laboratories in Albuquerque, New Mexico aims to address this disparity with a custom-made assembly language for quantum computation.

Unprecedented Map of the Sun’s Magnetic Field Created by CLASP2 Space Experiment

Posted by in categories: energy, physics, space

Every day space telescopes provide spectacular images of the solar activity. However, their instruments are blind to its main driver: the magnetic field in the outer layers of the solar atmosphere, where the explosive events that occasionally affect the Earth occur. The extraordinary observations of the polarization of the Sun’s ultraviolet light achieved by the CLASP2 mission have made it possible to map the magnetic field throughout the entire solar atmosphere, from the photosphere until the base of the extremely hot corona. This investigation, published today in the journal Science Advances, has been carried out by the international team responsible for this suborbital experiment, which includes several scientists of the POLMAG group of the Instituto de Astrofísica de Canarias (IAC).

The chromosphere is a very important region of the solar atmosphere spanning a few thousand kilometers between the relatively thin and cool photosphere (with temperatures of a few thousand degrees) and the hot and extended corona (with temperatures above a million degrees). Although the temperature of the chromosphere is about one hundred times lower than that of the corona, the chromosphere has a far higher density, and thus much more energy is required to sustain it. Moreover, the mechanical energy necessary to heat the corona needs to traverse the chromosphere, making it a crucial interface region for the solution of many of the key problems in solar and stellar physics. One of the current scientific challenges is to understand the origin of the violent activity of the solar atmosphere, which on some occasions perturb the Earth’s magnetosphere with serious consequences for our present technological world.
