China’s quantum science satellite begins ‘spooky’ and ‘unhackable’ experiments

Posted by in categories: cybercrime/malcode, quantum physics, satellites, science

Hope folks are realizing this is happening and now real. Not sure what experiments their doing as they have already been experimenting already on hacking.


The world’s first quantum science and communications satellite has been handed over to Chinese scientists for the official start of experiments to test the phenomena of quantum entanglement and ‘unhackable’ quantum communication.

The Quantum Experiments at Space Scale (QUESS) satellite was launched on August 15 last year and soon after began testing its payloads and space-to-ground links.

Quantum oracle: AI predicts and fixes qubit failure

Posted by in categories: quantum physics, robotics/AI

We’re definitely not a ways off for QC being available to the masses unless you believe 5 years is a long time.


Machine learning kept unstable quantum bits in line – even before they wavered. Cathal O’Connell reports.

Now Quantum Computers Can Send Information Using a Single Particle of Light

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

Physicists at Princeton University have revealed a device they’ve created that will allow a single electron to transfer its quantum information to a photon. This is a revolutionary breakthrough for the team as it gets them one step closer to producing the ultimate quantum computer. The device is the result of five years worth of research and could accelerate the world of quantum computing no end.

Seeing the quantum future… literally

Posted by in categories: computing, quantum physics

Scientists at the University of Sydney have demonstrated the ability to “see” the future of quantum systems, and used that knowledge to preempt their demise, in a major achievement that could help bring the strange and powerful world of quantum technology closer to reality.

The applications of quantum-enabled technologies are compelling and already demonstrating significant impacts — especially in the realm of sensing and metrology. And the potential to build exceptionally powerful quantum computers using quantum bits, or qubits, is driving investment from the world’s largest companies.

However a significant obstacle to building reliable quantum technologies has been the randomisation of by their environments, or decoherence, which effectively destroys the useful quantum character.

This Material Could Reveal the Link Between Classical Physics and the Quantum Realm

Posted by in categories: energy, quantum physics

In Brief

  • Scientists are a little bit closer to unlocking the mystery of how the rules of the quantum realm translate to the rules of the classical physics of the observable world.
  • Experts predict that the materials used in this research, topological insulators, will play a key role in furthering this development.

It’s no surprise that quantum physics can be disorienting to the casual observer; after all, it does follow its own set of rules quite different from those of classical physics which rule over our everyday experience. In the quantum realm, things can and cannot be at the same time (to a certain extent) or are continually moving without spending energy. These don’t apply to the physics of macro-level matter.

Next-Gen Computing Game Changers: Quantum Computers And Beyond

Posted by in categories: computing, quantum physics

Although this was published last week; I got a request to share again for those who missed it.


While “product-market fit” may have become the mantra for many tech companies and investors, we believe there are still plenty of companies out there with their eyes set on building true game-changing technologies. In our Game Changers report, we identified 8 categories of innovation that could have the greatest impact on how we live. Among these is next-gen computing — specifically, quantum computers and DNA data-writing technologies, which have the potential to fast-track innovation across industries.

Quantum computers can solve real-world problems much faster than traditional computers — and their capacity is only increasing. Meanwhile, using synthetic DNA to store vastly more data than a typical chip has the potential to revolutionize computers’ memory capacity.

Greek researchers working at the National and Kapodistrian University of Athens (EKPA) optical communication photonic technology laboratory have developed an artificial “neuron” that simulates fundamental functions of the human brain, at speeds that are many orders of magnitude higher.

A paper on the new breakthrough made by the Greek team, led by Prof. Dimitris Syvridis with Dr. Charis Mesaritakis as main researcher and with Alexandros Kapsalis and Adonis Bogris listed as authors, was published in the “Scientific Reports” section of the science journal “Nature” on December 19.

New Cooling Technique Could Aid Development Of Quantum Computers

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

Nice.


A sophisticated cooling technique — using lasers to cool individual atoms — was demonstrated at the National Institute of Standards in Technology in 1978, and is now used in a wide array of precise applications, such as atomic clocks. Using the same principle, NIST physicists have now “cooled a mechanical object to a temperature lower than previously thought possible,” passing the so-called “quantum limit” which imposes limits on accuracy for quantum scale measurements.

Described in a paper titled “Sideband cooling beyond the quantum backaction limit with squeezed light,” published Thursday in the journal Nature, the technique could theoretically be used to cool objects to absolute zero, when matter exhibits almost no energy or motion.
