Algorithm to increase the efficiency of quantum computers

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

Quantum computers have the potential to solve important problems that are beyond reach even for the most powerful supercomputers, but they require an entirely new way of programming and creating algorithms.

Universities and major tech companies are spearheading research on how to develop these new algorithms. In a recent collaboration between University of Helsinki, Aalto University, University of Turku, and IBM Research Europe-Zurich, a team of researchers have developed a new method to speed up calculations on quantum computers. The results are published in the journal PRX Quantum of the American Physical Society.

“Unlike classical computers, which use bits to store ones and zeros, information is stored in the qubits of a quantum processor in the form of a , or a wavefunction,” says postdoctoral researcher Guillermo García-Pérez from the Department of Physics at the University of Helsinki, first author of the paper.

Physical features boost the efficiency of quantum simulations

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

Recent theoretical breakthroughs have settled two long-standing questions about the viability of simulating quantum systems on future quantum computers, overcoming challenges from complexity analyses to enable more advanced algorithms. Featured in two publications, the work by a quantum team at Los Alamos National Laboratory shows that physical properties of quantum systems allow for faster simulation techniques.

“Algorithms based on this work will be needed for the first full-scale demonstration of quantum simulations on quantum computers,” said Rolando Somma, a quantum theorist at Los Alamos and coauthor on the two papers.

SpaceX Begins Building Orbital Starship Launch Pad in Unexpected Location

Posted by in categories: Elon Musk, space travel

SpaceX aims to launch the first orbital test of a full-stack Starship as soon as January. But instead of the Texas “Starbase” facility where prototypes of Starship’s upper stage have been made and tested, the orbital flight will launch from the Kennedy Space Center in Florida, CEO Elon Musk said Friday.

“Construction of Starship orbital launch pad at the Cape has begun,” Musk tweeted. In later comments he confirmed that the launch pad is located at the historic Launch Complex 39A, the same pad used for SpaceX commercial crew flights to the International Space Station for NASA.

“39A is hallowed spaceflight ground—no place more deserving of a Starship launch pad!” Musk explained in a separate tweet. “Will have similar, but improved, ground systems and tower to Starbase.”

Newborn stars contributed to this chaos.


Any parent of newborns know just how powerful even small things are.

The same is true in space, where baby stars in a section of a nebula, or gas cloud, create a series a powerful shockwaves visible in a new Hubble Space Telescope image.

Electric Sky wins DARPA grant to work on focused power beaming system for drones

Posted by in categories: business, drones, energy

Electric Sky says it’s begun building its first transmitter for providing tightly focused wireless power to drones in flight, thanks to funding from DARPA.


A startup called Electric Sky says it’s begun building its first Whisper Beam transmitter for providing tightly focused wireless power to drones in flight, thanks to a $225,000 award from the Defense Advanced Research Projects Agency.

Electric Sky will use the six-month Phase I award, granted through DARPA’s Small Business Innovation Research program, to explore ways to adapt its wireless architecture to power a swarm of drones.

Consciousness & Time | Part III of Consciousness: Evolution of the Mind (2021) Documentary

Posted by in categories: computing, education, information science, neuroscience, quantum physics, singularity

Most physicists and philosophers now agree that time is emergent while Digital Presentism denotes: Time emerges from complex qualia computing at the level of observer experiential reality. Time emerges from experiential data, it’s an epiphenomenon of consciousness. From moment to moment, you are co-writing your own story, co-producing your own “participatory reality” — your stream of consciousness is not subject to some kind of deterministic “script.” You are entitled to degrees of freedom. If we are to create high fidelity first-person simulated realities that also may be part of intersubjectivity-based Metaverse, then D-Theory of Time gives us a clear-cut guiding principle for doing just that.

Physicists discover special transverse sound wave

Posted by in category: physics

Can you imagine sound traveling in the same way as light does? A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: The airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered scientists’ previous beliefs about the sound wave, opening an avenue to the development of novel applications in acoustic communications, acoustic sensing and imaging.

The research was initiated and co-led by Dr. Shubo Wang, Assistant Professor in the Department of Physics at CityU, and conducted in collaboration with scientists from Hong Kong Baptist University (HKBU) and the Hong Kong University of Science and Technology (HKUST). It was published in Nature Communications, titled “Spin-orbit interactions of transverse sound.”
