Accessible Photon Emission Could Bring Quantum Computing Out of the Lab

Researchers from the Tyndall National Institute in Cork have created micro-structures shaped like small pyramids that can create entangled photons. Does this mean that quantum computers are closer than we realize?

Quantum computers have been the stuff of science fiction for the past few decades. In recent times, quantum computers have slowly become more of a reality with some machines successfully solving real world problems such as games and path finding algorithms.

But why are quantum computers so desired by tech firms and why is there so much research into the field? Silicon has been incredibly loyal to the tech world for the past 50 years, giving us the point contact transistor in 1947. Now, silicon is at the center of technology with computers, tablets, smartphones, the IoT, and even everyday items. In fact, you cannot walk down a city street without being in range of some Wi-Fi network or influence from a small silicon device.

Insight: Toro Rosso backer says F1 teams should pay more attention to cyber attacks // F1 News // James Allen on F1 – The official James Allen website on F1

QC and Formula 1 another opportunity and believer.

In the latest of our occasional series of interviews with interesting players behind the scenes in Formula 1 we meet a Russian scientist, who is keeping the Toro Rosso safe from cyber attacks and who has big plans for using quantum computers to create new F1 materials.

Acronis is a data support and protection business that was founded in 2003. It reportedly has five million personal consumers and 500,000 businesses using its technology in over 145 countries and offers services such as cloud security, data back up and recovery support.

Here James Allen interviews Acronis CEO Serguei Beloussov, who has a PhD in physics and sits on the board of directors at the Russian Quantum Center and Centre for Quantum Technologies in Singapore, about why Acronis has decided to spend its money on F1.

If You Want To Protect Your Business, You Need To Start Thinking About Quantum Encryption Now

Nice write up about why businesses need to worry about QC sooner v. later. Glad to see more spreading the word.

It’s coming sooner than you think.

Viewpoint: A New Era for the Ampere

Improving Precision with Quantum — A new Precise Quantum Current Source developed to ensure calibrated currents meet the new redefined International System of Units.

A precision quantum current source has been designed to calibrate currents in terms of the soon-to-be-redefined International System of Units.

Metrologists are conservative by nature, knowing that the premature adoption of a new measurement standard could lead to confusion in both science and commerce. So it is a big deal that the International System of Units (SI) is poised to undergo its first major overhaul since its birth in 1960. Two years from now at the General Conference on Weights and Measures in Paris, officials will adopt a new SI in which every unit can be obtained from fixed values of several fundamental constants [1]. All eyes are on the kilogram, which will no longer be defined by the mass of a cylinder of platinum-iridium alloy that has been kept in a Parisian vault since it was fabricated in 1889. Somewhat overlooked, however, are advances in standards for electrical resistance and voltage, without which the new SI would not be possible.

Two electrons go on a quantum walk and end up in a qudit: Russian scientists find a way to reliably connect quantum elements

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.

In a matter of hours, a quantum computer would be able to hack through the most popular cryptosystem used even in your web browser. As far as more benevolent applications are concerned, a quantum computer would be capable of molecular modeling that takes into account all interactions between the particles involved. This in turn would enable the development of highly efficient solar cells and new drugs. To have practical applications, a quantum computer needs to incorporate hundreds or even thousands of qubits. And that is where it gets tricky.

Quantum leaps needed for new computer approach

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.
