Australia opens quantum computing lab in Sydney

Posted by in categories: quantum physics, supercomputing

I am totally jealous right now!


Australia opened a new quantum computing lab at the University of New South Wales (UNSW).

This follows the government’s $26-million investment in the Centre of Excellence for Quantum Computation & Communication Technology (CQC2T) as part of the National Innovation and Science Agenda. The government’s investment is supported by $10 million each from Telstra and the Commonwealth Bank of Australia (CBA).

An experiment seeks to make quantum physics visible to the naked eye

Posted by in categories: particle physics, quantum physics

Predictions from quantum physics have been confirmed by countless experiments, but no one has yet detected the quantum physical effect of entanglement directly with the naked eye. This should now be possible thanks to an experiment proposed by a team around a theoretical physicist at the University of Basel. The experiment might pave the way for new applications in quantum physics.

Quantum physics is more than 100 years old, but even today is still sometimes met with wonderment. This applies, for example, to entanglement, a quantum physical phenomenon that can be observed between atoms or photons (light particles): when two of these particles are entangled, the physical state of the two particles can no longer be described independently, only the total system that both particles form together.

Despite this peculiarity, entangled photons are part of the real world, as has been proven in many experiments. And yet no one has observed entangled photons directly. This is because only single or a handful of entangled photons can be produced with the available technology, and this number is too low for the to perceive these photons as light.

Bill Gates: No reason to fear AI yet; in fact, it could be your new assistant

Posted by in categories: computing, drones, quantum physics, robotics/AI, terrorism

I am so glad to see this from Bill. Until we drastically improve the under pinning technology to an advance mature version of Quantum Computing; AI is not a threat in the non-criminal use. The only danger is when terrorists, drug cartels, and other criminals uses AI such as drones, robotics, bots, etc. to attack, burglarize, murder, apply their terror, etc.; and that is not AI doing these things on their own.

Quantum sensors for high-precision magnetometry of superconductors

Posted by in categories: electronics, nanotechnology, quantum physics

Quantum Sensors enables precise imaging of magnetic fields of superconductors.


Scientists at the Swiss Nanoscience Institute and the Department of Physics at the University of Basel have developed a new method that has enabled them to image magnetic fields on the nanometer scale at temperatures close to absolute zero for the first time. They used spins in special diamonds as quantum sensors in a new kind of microscope to generate images of magnetic fields in superconductors with unrivaled precision. In this way the researchers were able to perform measurements that permit new insights in solid state physics, as they report in Nature Nanotechnology.

Researchers in the group led by the Georg-H. Endress Professor Patrick Maletinsky have been conducting research into so-called nitrogen-vacancy centers (NV centers) in diamonds for several years in order to use them as high-precision sensors. The NV centers are natural defects in the diamond crystal lattice. The electrons contained in the NVs can be excited and manipulated with light, and react sensitively to electrical and magnetic fields they are exposed to. It is the spin of these electrons that changes depending on the environment and that can be recorded using various measurement methods.

Maletinsky and his team have managed to place single NV spins at the tips of atomic force microscopes to perform nanoscale magnetic field imaging. So far, such analyses have always been conducted at room temperature. However, numerous fields of application require operation at temperatures close to absolute zero. Superconducting materials, for example, only develop their special properties at very low temperatures around −200°C. They then conduct electric currents without loss and can develop exotic magnetic properties with the formation of so-called vortices.

Could Aluminum Nitride Be Engineered to Produce Quantum Bits?

Posted by in categories: encryption, quantum physics, supercomputing

Interesting insight on Aluminum Nitride used to create Qubits.

http:///articles/could-aluminum-nitride-be-engineered-to-pro…nteresting insight.


Newswise — Quantum computers have the potential to break common cryptography techniques, search huge datasets and simulate quantum systems in a fraction of the time it would take today’s computers. But before this can happen, engineers need to be able to harness the properties of quantum bits or qubits.

Autonomous quantum error correction method greatly increases qubit coherence times

Posted by in categories: computing, quantum physics, robotics/AI

Closing the instability gap.


(Phys.org)—It might be said that the most difficult part of building a quantum computer is not figuring out how to make it compute, but rather finding a way to deal with all of the errors that it inevitably makes. Errors arise because of the constant interaction between the qubits and their environment, which can result in photon loss, which in turn causes the qubits to randomly flip to an incorrect state.

In order to flip the qubits back to their correct states, physicists have been developing an assortment of quantum techniques. Most of them work by repeatedly making measurements on the system to detect errors and then correct the errors before they can proliferate. These approaches typically have a very large overhead, where a large portion of the computing power goes to correcting errors.

NIST aiming for quantum-proof crypto

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

Due to the pace of Quantum Computing is developing; NIST is rushing to create a Quantum proof cryptographic algorithms to prevent QC hacking. Like I have stated, I believe we’re now less that 7 years away for QC being in many mainstream devices, infrastructure, etc. And, China and it’s partnership with Australia; the race is now on and hotter than ever.


The National Institute for Standards and Technology has begun to look into quantum cybersecurity, according to a new report that details and plans out ways scientists could protect these futuristic computers.

Futuristic ‘post-quantum’ cryptography is subject of UWT symposium

Posted by in categories: cybercrime/malcode, encryption, information science, quantum physics, supercomputing

Post-quantum cryptography discussion in Tacoma WA on May 5th discussing hacking by QC hackers and leveraging Cryptography algorithms to offset the attacks; may be of interest to sit in and even join in the debates. I will try attend if I can because it would be interesting to see the arguments raised and see the responses.


The University of Washington Tacoma Institute of Technology will present a discussion about the esoteric field of post-quantum cryptography at the Northwest Cybersecurity Symposium on May 5.

“I’ve been researching post-quantum cryptography for years, finding ways to protect against a threat that doesn’t yet exist,” said Anderson Nascimento, assistant professor of computer science at the institute, in a release.

Important effect observed in development of quantum storage

Posted by in categories: computing, mathematics, quantum physics

I read this article and it’s complaints about the fragile effects of data processing and storing information in a Quantum Computing platform. However, I suggest the writer to review the news released 2 weeks ago about the new Quantum Data Bus highlighted by PC World, GizMag, etc. It is about to go live in the near future. Also, another article to consider is today’s Science Daily articile on electron spin currents which highlights how this technique effectively processes information.


Rare-earth materials are prime candidates for storing quantum information, because the undesirable interaction with their environment is extremely weak. Consequently however, this lack of interaction implies a very small response to light, making it hard to read and write data. Leiden physicists have now observed a record-high Purcell effect, which enhances the material’s interaction with light. Publication on April 25 in Nature Photonics (“Multidimensional Purcell effect in an ytterbium-doped ring resonator”).

Ordinary computers perform calculations with bits—ones and zeros. Quantum computers on the other hand use qubits. These information units are a superposition of 0 and 1; they represent simultaneously a zero and a one. It enables quantum computers to process information in a totally different way, making them exponentially faster for certain tasks, like solving mathematical problems or decoding encryptions.

The light stuff: A brand-new way to produce electron spin currents

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

With apologies to Isaac Asimov, the most exciting phase to hear in science isn’t “Eureka,” but “That’s funny…”

A “that’s funny” moment in a Colorado State University physics lab has led to a fundamental discovery that could play a key role in next-generation microelectronics.

Publishing in Nature Physics April 25, the scientists, led by Professor of Physics Mingzhong Wu in CSU’s College of Natural Sciences, are the first to demonstrate using non-polarized light to produce in a metal what’s called a spin voltage — a unit of power produced from the quantum spinning of an individual electron. Controlling electron spins for use in memory and logic applications is a relatively new field called spin electronics, or spintronics, and the subject of the 2007 Nobel Prize in Physics.
