Researchers in Russia say they've developed and tested the world's first blockchain that won't be vulnerable to encryption-breaking attacks from future quantum computers.

Quantum computers finally seem to be coming of age with promises of "quantum supremacy" by the end of the year. But there’s a problem-very few people know how to work them.
Quantum communication is a strange beast, but one of the weirdest proposed forms of it is called counterfactual communication - a type of quantum communication where no particles travel between two recipients.
China builds ten qubit quantum computer, they will scale to 20 qubits by end of this year and could beat the performance of any regular computer next year with a 30 qubit system.
How fast will a quantum computer be able to calculate? While fully functional versions of these long-sought technological marvels have yet to be built, one theorist at the National Institute of Standards and Technology (NIST) has shown that, if they can be realized, there may be fewer limits to their speed than previously put forth.
U.S. officials and scientists have warned that the country that dominates the exascale era will have an edge in everything from business to national security to the military.
Scientists have trained a quantum computer to recognize trees. That may not seem like a big deal, but the result means that researchers are a step closer to using such computers for complicated machine learning problems like pattern recognition and computer vision.
Attempts at cloning a quantum system result in the introduction of imperfections in the state of the copies. This is a consequence of the no-cloning theorem, which is a fundamental law of quantum physics and the backbone of security for quantum communications. Although perfect copies are prohibited, a quantum state may be copied with maximal accuracy via
It's the first time quantum has been used to fight cyber crime, and if it works, it could reshape how security analysts protect their networks from harm.
Pulling together quantum-resistant cryptography will take time, and NIST feels that, unless it starts now, that new cryptography won’t be ready.
