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 error correction 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.

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.

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.

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.

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.

Transporting information from one place to another is a key part of any computing platform, and now researchers have figured out a way to make it possible in the quantum world.

To prove their point, they demonstrated what’s known as perfect state transfer on a photonic qubit that’s entangled with another qubit at a different location.

In traditional computing, numbers are represented by either 0s or 1s. Quantum computing relies on atomic-scale quantum bits, or “qubits,” that can be simultaneously 0 and 1—a state known as superposition. Quantum bits can also become “entangled” so that they are dependent on one another even across distances.

Excellent news!!!!!

The Quantum Innovation Center or Qubiz has been launched in Copenhagen with the goal of translating quantum physics into practical quantum technology. The Danish project involves the Niels Bohr Institute at the University of Copenhagen, the Technical University of Denmark DTU, and Aarhus University, along with 18 industrial partners. Qubiz will be building on the very strong Danish research platform within quantum technology, a platform that has its origin in Niels Bohr’s pioneering work 100 years ago.

The CEO for the new Center is Søren Isaksen, who previously served as the CTO of the NKT Group and is a member and chairmen of various research councils. In addition to leading the center, his job will be to reach out to Danish and foreign companies and, with the researchers, to help find out where there is potential for starting new businesses. A 2-year seed funding grant of 11M EUR from the Innovation Fund Denmark enables the hiring of new employees with business and engineering backgrounds, as well as researchers.

According to Isaksen, the Center will engage with existing businesses, Danish as well as international companies, to develop new products and lay the foundation for new businesses. On April 15, Qubiz held a kick-off event that included seven elevator-pitches presenting potential startups—two of these have now being established and more are on the way.

Quantum entanglement is thought to be one of the trickiest concepts in science, but the core issues are simple. And once understood, entanglement opens up a richer understanding of concepts such as the “many worlds” of quantum theory.

More highlights around the correlation of Data Compression and Quantum Entanglement. I do believe as we move forward with Quantum Computing (QC) that we will discover many other correlations and re-usage of existing technology principles with Quantum Computing.
