The exciting new age of quantum computing
Posted by Karen Hurst in categories: biotech/medical, computing, encryption, military, quantum physics, security, space travel
What does the future hold for computing? Experts at the Networked Quantum Information Technologies Hub (NQIT), based at Oxford University, believe our next great technological leap lies in the development of quantum computing.
Quantum computers could solve problems it takes a conventional computer longer than the lifetime of the universe to solve. This could bring new possibilities, such as advanced drug development, superior military intelligence, greater opportunities for space exploration and enhanced encryption security.

Quantum Teleportation Could Revolutionize Modern Phone And Internet Communication
Posted by Karen Hurst in categories: encryption, finance, internet, mobile phones, quantum physics, space, transportation
I never get tired of articles highlighting the potential around leveraging Quantum teleporting as a method to replace networks and communications. Now the real question is how soon and how much of the existing infrastructure will need to be replaced to begin taking advantage of this technology earlier than others? As with most things, governments are often early adopters as well as Financial Services and ISPs are a close 2nd in the adoption of such technologies.
An experiment conducted about quantum teleportation could improve and transform the modern phone and Internet communication by having highly secure and encrypted messaging.
A recent study has suggested that comet outbursts are caused by avalanches and not geysers.

How quantum effects could improve artificial intelligence
Posted by Andreas Matt in categories: computing, encryption, quantum physics, robotics/AI, sustainability
(Phys.org)—Over the past few decades, quantum effects have greatly improved many areas of information science, including computing, cryptography, and secure communication. More recently, research has suggested that quantum effects could offer similar advantages for the emerging field of quantum machine learning (a subfield of artificial intelligence), leading to more intelligent machines that learn quickly and efficiently by interacting with their environments.
In a new study published in Physical Review Letters, Vedran Dunjko and coauthors have added to this research, showing that quantum effects can likely offer significant benefits to machine learning.
“The progress in machine learning critically relies on processing power,” Dunjko, a physicist at the University of Innsbruck in Austria, told Phys.org. “Moreover, the type of underlying information processing that many aspects of machine learning rely upon is particularly amenable to quantum enhancements. As quantum technologies emerge, quantum machine learning will play an instrumental role in our society—including deepening our understanding of climate change, assisting in the development of new medicine and therapies, and also in settings relying on learning through interaction, which is vital in automated cars and smart factories.”

No satellites needed for next-gen navigation system that uses “signals of opportunity”
Posted by Shane Hinshaw in categories: encryption, internet, military, mobile phones, robotics/AI, satellites
The Global Positioning System (GPS) is a great navigation aid – unless you lose the signal while negotiating a complicated spaghetti junction. That’s bad enough for conventional cars, but for autonomous vehicles it could be catastrophic, so the University of California, Riverside’s Autonomous Systems Perception, Intelligence, and Navigation (ASPIN) Laboratory under Zak Kassas is developing an alternative navigation system that uses secondary radio signals, such as from cell phone systems and Wi-Fi to either complement existing GPS-based systems or as a standalone alternative that is claimed to be highly reliable, consistent, and tamper-proof.
Today, there are two global satellite navigation systems in operation, the US GPS and the Russian GLONASS, with the European Galileo system set to become fully operational in the next few years, and plans for the Chinese Beidou system to extend globally by 2020. These have revolutionized navigation, surveying, and a dozen other fields, but GPS and related systems still leave much to be desired. By their nature, GPS signals are weak and positions need to be confirmed by several satellites, so built up areas or mountainous areas can make the system useless. In addition, GPS signals can be deliberately or accidentally jammed or spoofed due to insufficient encryption and other protections.

Teleporting Toward a Quantum Internet
Posted by Karen Hurst in categories: encryption, internet, mobile phones, quantum physics
New experiments in Calgary tested quantum teleportation in actual infrastructure, representing a major step forward for the technology.
Quantum physics is a field that appears to give scientists superpowers. Those who understand the world of extremely small or cold particles can perform amazing feats with them — including teleportation — that appear to bend reality.
The science behind these feats is complicated, and until recently, didn’t exist outside of lab settings. But that’s changing: researchers have begun to implement quantum teleportation in real-world contexts. Being able to do so just might revolutionize modern phone and Internet communications, leading to highly secure, encrypted messaging.

BT And Toshiba Showcase UK’s First Secure Quantum Communications
Posted by Karen Hurst in categories: encryption, quantum physics
BT and Toshiba have showcased the UK’s first use of secure quantum communication at the telecoms company’s research and development centre in Ipswich.
The showcase demonstrates the use of quantum cryptography for communications over fibre optic cabling. By exploiting the quantum states of photons, the most visible elementary particles in the electromagnetic spectrum, the cryptographic technique can be used to communicate securely over normal fibre cables.

Will Quantum Computers Kill Bitcoin?
Posted by Karen Hurst in categories: bitcoin, cybercrime/malcode, encryption, quantum physics
Since they were first theorized by the physicist Richard Feynman in 1982, quantum computers have promised to bring about a new era of computing. It is only relatively recently that theory has translated into significant real-world advances, with the likes of Google, NASA and the CIA working towards building a quantum computer. Computer scientists are now warning that the arrival of the ultra-powerful machines will cripple current encryption methods and as a result bring a close to the great bitcoin experiment—collapsing the technological foundations that bitcoin is built upon.
“Bitcoin is definitely not quantum computer proof,” Andersen Cheng, co-founder of U.K. cybersecurity firm Post Quantum, tells Newsweek. “Bitcoin will expire the very day the first quantum computer appears.”
The danger quantum computers pose to bitcoin, Cheng explains, is in the cryptography surrounding what is known as the public and private keys—a set of numbers used to facilitate transactions. Users of bitcoin have a public key and a private key. In order to receive bitcoin, the recipient shares the public key with the sender, but in order to spend it they need their private key, which only they know. If somebody else is able to learn the private key, they can spend all the bitcoin.

Quantum Computing Could Cripple Encryption; Bitcoin’s Role
Posted by Karen Hurst in categories: bitcoin, business, cybercrime/malcode, encryption, government, quantum physics
Earlier this week, Canada’s electronic spy agency the Communications Security Establishment warned government agencies and businesses against quantum mechanics, which could cripple the majority of encryption methods implemented by leading corporations and agencies globally.
Governments and private companies employ a variety of cryptographic security systems and protocols to protect and store important data. Amongst these encryption methods, the most popular system is public key cryptography (PKC), which can be integrated onto a wide range of software, platforms, and applications to encrypt data.
The Communications Security Establishment and its chief Greta Bossenmaier believes that quantum computing is technically capable of targeting PKC-based encryption methods, making data vulnerable to security breaches and hacking attempts from foreign state spies and anonymous hacking groups.
