Post-Quantum Cryptography Aims To Fend Off Advanced Hack Attacks

Posted by in categories: cybercrime/malcode, encryption, internet, quantum physics

Luv it; more believers.


Quantum computers promise to enable faster, far more complex calculations than today’s silicon chip-based computers. But they also raise the possibility that future computers could retroactively break the security of any digital communications that exist today, which is why Google is experimenting with something called “post-quantum cryptography.”

While quantum computer development remains in its early stages, some such computers are already in operation. In theory, future generations of quantum computers could “decrypt any Internet communication that was recorded today, and many types of information need to remain confidential for decades,” software engineer Matt Braithwaite wrote yesterday in a post on Google’s security blog. “Thus even the possibility of a future quantum computer is something that we should be thinking about today.”

Weird quantum effects travel over hundreds of miles

Posted by in categories: particle physics, quantum physics

I shared this yesterday; however, another article with another spin (no pun intended)


Working at the Massachusetts Institute of Technology’s (MIT) Fermilab physics laboratory in Illinois, a team of physicists studied the states of neutrinos, among the smallest components of an atom.

Weird quantum effects stretch across hundreds of miles

Posted by in categories: particle physics, quantum physics

Interesting study occurring on subatomic particles (aka neutrinos) in how they can be in superposition, without individual identities, when traveling hundreds of miles.

Now, MIT physicists have found that subatomic particles called can be in superposition, without individual identities, when traveling hundreds of miles. Their results, to be published later this month in Physical Review Letters, represent the longest distance over which quantum mechanics has been tested to date.

The birth of quantum holography: Making holograms of single light particles!

Posted by in categories: particle physics, quantum physics

Until quite recently, creating a hologram of a single photon was believed to be impossible due to fundamental laws of physics. However, scientists at the Faculty of Physics, University of Warsaw, have successfully applied concepts of classical holography to the world of quantum phenomena. A new measurement technique has enabled them to register the first ever hologram of a single light particle, thereby shedding new light on the foundations of quantum mechanics.

Scientists at the Faculty of Physics, University of Warsaw, have created the first ever hologram of a single light particle. The spectacular experiment, reported in the journal Nature Photonics, was conducted by Dr. Radoslaw Chrapkiewicz and Michal Jachura under the supervision of Dr. Wojciech Wasilewski and Prof. Konrad Banaszek. Their successful registering of the hologram of a single photon heralds a new era in holography: quantum holography, which promises to offer a whole new perspective on quantum phenomena.

“We performed a relatively simple experiment to measure and view something incredibly difficult to observe: the shape of wavefronts of a single photon,” says Dr. Chrapkiewicz.

Research breakthrough towards ‘practical’ quantum computing future

Posted by in categories: computing, quantum physics

This truly makes QC more practical on many fronts. First, no need for QC to reside in an “icebox” room/ environment. Second, with the recent findings on making quantum computing scalable; we now have a method in place to not make QC devices over heat as well. So, again another major step forward by Sydney and their partners in Switzerland and Germany.

A group of international researchers, including a leading research from the University of Sydney, has made a breakthrough discovery, making a conducting carbon material that they demonstrated could be used to perform quantum computing at room temperature, rather than near absolute zero (−273°C).

Can we find a quantum-resistant algorithm before it’s too late?

Posted by in categories: computing, information science, internet, quantum physics, security

The warning from QuintessenceLabs’ CTO John Leisoboer is stark. “When sufficiently powerful quantum computers become generally available,” he says, “it’s guaranteed to break all existing cryptographic systems that we know of.”

In other words, he adds, “Everything that we’re doing today will be broken.”

It’s a sentiment echoed by Google’s Chrome security software engineer Matt Braithwaite who wrote in a blog post earlier this month that “a hypothetical, future quantum computer would be able to retrospectively decrypt any internet communication that was recorded today”.

Primitive Quantum Computers Are Already Outperforming Current Machines

A team has used simple quantum processors to run “quantum walk” algorithms, showing that even primitive quantum computers can outperform the classical variety in certain scenarios—and suggesting that the age of quantum computing may be closer than we imagined.

By now, most readers of Futurism are probably pretty well acquainted with the concept (and fantastic promise) of quantum computing.
