This is a BIG DEAL in QC, and Russian Scientists solved it.

Abstract: Scientists from the Institute of Physics and Technology of the Russian Academy of Sciences and MIPT have let two electrons loose in a system of quantum dots to create a quantum computer memory cell of a higher dimension than a qubit (a quantum bit). In their study published in Scientific Reports, the researchers demonstrate for the first time how quantum walks of several electrons can help to implement quantum computation.

“By studying the system with two electrons, we solved the problems faced in the general case of two identical interacting particles. This paves the way toward compact high-level quantum structures,” comments Leonid Fedichkin, Expert at the Russian Academy of Sciences, Vice-Director for Science at NIX (a Russian computer company), and Associate Professor at MIPT’s Department of Theoretical Physics.

Researchers at University of California, Santa Barbara, have designed a functional nanoscale computing element that could be packed into a space no bigger than 50 nanometres on any side.

In 1959, renowned physicist Richard Feynman, in his talk “Plenty of Room at the Bottom” spoke of a future in which tiny machines could perform huge feats. Like many forward-looking concepts, his molecule and atom-sized world remained for years in the realm of science fiction. And then, scientists and other creative thinkers began to realise Feynman’s nanotechnological visions.

Introduction

Moore’s Law says that the number of transistors per square inch will double approximately every 18 months. This article will show how many technologies are providing us with a new Virtual Moore’s Law that proves computer performance will at least double every 18 months for the foreseeable future thanks to many new technological developments.

This Virtual Moore’s Law is propelling us towards the Singularity where the invention of artificial superintelligence will abruptly trigger runaway technological growth, resulting in unfathomable changes to human civilization.

Going Vertical

In the first of my “proof” articles two years ago, I described how it has become harder to miniaturize transistors, causing computing to go vertical instead. 2 years ago, Samsung was mass producing 24-layer 3D NAND chips and had announced 32-layer chips. As I write this, Samsung is mass producing 48-layer 3D NAND chips with 64-layer chips rumored to appear within a month or so. Even more importantly, it is expected that by the end of 2017, the majority of NAND chips produced by all companies will be 3D. Currently Samsung and its competitors are working 24/7 to transform their 2D factories to 3D factories causing a dramatic change in how NAND flash chips are created.

Excellent overview on BMI technology.

Less than a century ago, Hans Berger, a German psychiatrist, was placing silver foil electrodes on his patients’ heads and observing small ripples of continuous electrical voltage emerging from these. These were the first human brain waves to ever be recorded. Since Hans Berger’s first recordings, our knowledge on the brain structure and function has developed considerably. We now have a much clearer understanding of the neuronal sources that generate these electrical signals and the technology that is now available allows us to get a much denser and accurate picture of how these electrical signals change in time and across the human scalp.

The recording and analysis of brain signals has advanced to a level where people are now able to control and interact with devices around them with the use of their brain signals. The field of brain-computer interfaces has in fact garnered huge interest during the past two decades, and the development of low-cost hardware solutions together with the continuously evolving signal analysis techniques, have brought this technology closer to market than ever before.

Microsoft has been working on quantum computing for years, but the company is coming out of stealth mode now and taking a more active role in quantum computer development. It wants to build a theoretical type of machine known as a topological quantum computer, despite the difficulty of doing so.

Scientists from MIT and Boston University have developed biological cells that can count and ‘remember’ cellular events by creating simple circuits through a series of genes that are activated in a precise order. These circuits, which the scientists say simulate computer chips, could be employed to tally the number of times a cell divides or to track a cycle of developmental stages. Such counting cells could also be used as biosensors to count the number of toxin exposures present in an environment.

Precise stimulation could be useful for visual prosthetics or brain-computer interfaces.

Glad that the author is highlighting the need for investment; however, the US government has had a quantum network since 1991. Wall Street, various overseas banks, ISPs, etc. well over a year to 2 years ago. And, tech has invested in QC for a decade or longer. So, the article raises the need for investing in QC; however, the investing is no longer experimental as it is now about the daily usage of this technology as well as planning for technical transformation that is coming in the next 5 to 7 years.

Researchers led by Lockheed Martin and IBM are pushing quantum computing prototypes and military applications.

An international team of scientists has succeeded in making further improvements to the lifetime of superconducting quantum circuits. An important prerequisite for the realization of high-performance quantum computers is that the stored data should remain intact for as long as possible. The researchers, including Jülich physicist Dr. Gianluigi Catelani, have developed and tested a technique that removes unpaired electrons from the circuits. These are known to shorten the qubit lifetime (Science, DOI: 10.1126/science.aah5844).

Quantum computers could one day achieve significantly higher computing speeds than conventional digital computers in performing certain types of tasks. Superconducting circuits belong to the most promising candidates for implementing quantum bits, known as qubits, with which quantum computers can store and process information. The high error rates associated with previously available qubits have up to now limited the size and efficiency of quantum computers. Dr. Gianluigi Catelani of the Peter Grünberg Institute (PGI-2) in Jülich, together with his colleagues has now found a way to prolong the time in which the superconducting circuits are able to store a “0” or a “1” without errors. Beside Catelani, the team comprises researchers working in the USA (Massachusetts Institute of Technology, Lincoln Laboratory, and the University of California, Berkeley), Japan (RIKEN), and Sweden (Chalmers University of Technology).

When superconducting materials are cooled below a material-specific critical temperature, electrons come together to form pairs; then current can flow without resistance. However, so far it has not been possible to build superconducting circuits in which all electrons bundle together. Single electrons remain unpaired and are unable to flow without resistance. Due to these so-called quasiparticles, energy is lost and this limits the length of time that the circuits can store data.
