NIST report says we urgently need more work in post-quantum cryptography

NIST report says we urgently need more work in post-quantum cryptography The study of how to keep encrypting messages even in the face of exponentially increased computing power is called “post-quantum cryptography,” or “quantum-resistant cryptography,” and the reality is that nobody knows quite how urgent it really is.Perhaps real, programmable quantum computers will never be a reality — but perhaps they will, and if they will, we’d better be ready.

This quantum ruler is the latest win against the many ‘nevers’ of quantum science

Its wavelengths, as we were able to create and use them, were in many cases too large for our purposes — even in the smallest range.Yet today, high-level quantum experiments regularly use entanglement as a tool to make even larger discoveries.

Electroluminescent diamonds could serve as the heart of quantum networks

Electroluminescent diamonds could serve as the heart of quantum networks But researchers might have solved one of the most challenging problems of quantum communications, by showing that diamonds can be used as ultra-bright single photon emitters.Until now, quantum dots have been the closest we’ve come to real-world quantum cryptographic systems, and bit leakage isn’t the only vulnerability in quantum cryptography.

Astronomers discover true nature of ‘giant space blob’

Astronomers discover true nature of ‘giant space blob’ We’ve been staring at the first such blob, called Lyman-Alpha blob 1 or LAB-1 for short, since we found it in 2000.The birth of galaxies is not a peaceful process, and these young galaxies could be bombarding the star nurseries with high-energy matter, driving star formation.

China claims to have invented quantum radar that could render entire US stealth fleet obsolete

China claims to have invented quantum radar that could render entire US stealth fleet obsolete The Chinese military says it has invented quantum radar, a breakthrough which, if true, would render the hundreds of billions of dollars the United States has invested into stealth technology obsolete.Like the original invention of radar, the advent of modern artillery, or radio communications, quantum radar could fundamentally transform the scope and nature of war.

The 2016 Nobel Prize in Physics goes to mathematicians working in Flatland

The 2016 Nobel Prize in Physics goes to mathematicians working in Flatland Michael Kosterlitz for “theoretical discoveries of topological phase transitions and topological phases of matter.When cooled to just a few degrees above absolute zero, and subjected to a perpendicular magnetic field of 15 Tesla (just barely weaker than the magnetic field required to levitate a frog), that conductive 2D layer started acting very differently.

In bid to achieve quantum encryption, China set to finish 2,000-kilometer 'quantum link'

In bid to achieve quantum encryption, China set to finish 2,000-kilometer 'quantum link' Now, China is nearing completion of another major facet in its push for a quantum phone at the capital building: a 2,000-kilometer fiber-optic line for ferrying quantum encryption keys.It’s the beginning of China’s roll-out of true quantum encryption technology.
