Scientists Just Made The First Quantum-Encrypted International Video Call
President Chunli Bai of the Chinese Academy of Sciences in Beijing had a meeting yesterday with President Anton Zeilinger of the Austria Academy of Sciences in Vienna.
Although 7,400 kilometres (4,600 miles) apart, they were certain no uninvited guests were eavesdropping thanks to the fact their video call was encrypted. Quantum style.
Just a few months ago, China was in the news for a landmark achievement in quantum communication, using a satellite called Micius to transmit entangled photons over a record distance.
Quantum teleportation through time-shifted AdS wormholes
Scholarly paper on building a time machine:
“Quantum teleportation through time-shifted AdS wormholes.
(Submitted on 30 Aug 2017)
Based on the work of Gao-Jafferis-Wall and Maldacena-Stanford-Yang, we observe that the time-shifted thermofield states of two entangled CFTs can be made traversable by an appropriate coupling of the two CFTs, or alternatively by the application of a modified quantum teleportation protocol. This provides evidence for the smoothness of the horizon for a large class of entangled states related to the thermofield by time-translations. The smoothness of these states has some relevance for the firewall paradox and the proposal that some observables in quantum gravity may be state-dependent. We notice that quantum teleportation through these entangled states could be used in a laboratory setup to implement a time-machine, which allows the observer to travel far in the future.”

Researchers Claim They Just Invented The “Ultimate” Method for Quantum Computing
A pair of Japanese researchers believe their quantum computing method will increase the number of qubits processed from the dozens to the millions.
Can the US Military Re-Invent the Microchip for the AI Era?
Trying to outrun the expiration of Moore’s Law.
As conventional microchip design reaches its limits, DARPA is pouring money into the specialty chips that might power tomorrow’s autonomous machines.
The coming AI revolution faces a big hurdle: today’s microchips.
It’s one thing to get a bunch of transistors on an integrated circuit to crunch numbers, even very large ones. But what the brain does is far more difficult. Processing vast amounts of visual data for use by huge, multi-cellular organism is very different from the narrow calculations of conventional math. The algorithms that will drive tomorrow’s autonomous cars, planes, and programs will be incredibly data-intensive, with needs well beyond what conventional chips were ever designed for. This is one reason for the hype surrounding quantum computing and neurosynaptic chips.
We Now Have an Equation That Explains How The Hell Quantum Chaos Behaves
While physicists have managed to wrap their minds around chaos theory in the macroscopic world, chaos also has its way at the quantum scale. And in many ways quantum chaos is even more perplexing than its large-scale counterpart.
Which is why it’s such a big deal that researchers have now presented a single equation that can predict how quantum chaos behaves.
This equation effectively explains the patterns within quantum chaos at the atomic level, and it could contribute to our understanding of everything from brain surgery to string theory.
This Quantum Theory Says Time Can Flow Backwards
Quantum physics throws all the rules of classical physics out the window. In the quantum world, particles can pass through solid walls, be in two places at once, and communicate over an infinite distance. And, if a handful of physicists are right, they can affect the past just as easily as they affect the future. That’s a theory known as quantum retrocausality, and researchers have good reasons to believe it’s true.
