Quantum physics shows that there is no such thing as ‘nothing.’ Even in a vacuum, particles can blink into and out of existence.
Julian Barbour, physicist, talks the illusion of time, the origin of the universe, and what is reality. He also discusses his newest book, “The Janus Point: A New Theory of Time,” which makes the radical argument that the growth of order drives the passage of time — and shapes the destiny of the universe.

According to reports from Spanish newspaper El País, researchers have discovered a way to speed up, slow down, and even reverse quantum time by taking advantage of unusual properties within a quantum world in specific ways. It’s a huge breakthrough, which the researchers have detailed in a series of six new papers featured in Advancing Physics.
The papers were originally published in 2018, and they detail how researchers were able to rewind time to a previous scene, as well as even skip several scenes forward. Being able to reverse and even control quantum time is a huge step forward, especially as we’ve seen increasing movements into quantum simulators.
The realm of quantum physics is a complex one, no doubt, and with analog quantum computers showing such promise at solving intense problems, it only seens fitting that research into controlling and reversing quantum time would prove so fruitful. The researchers say that the control they can acquire on the quantum world is very similar to controlling a movie.
A team led by Boston College has devised a new quantum sensor method to image and comprehend the source of photocurrent flow in Weyl semimetals.

This article will explain the most important parts of the Quantum Approximate Optimization Algorithm (QAOA). QAOA is a machine learning algorithm that you can use to solve combinatorial optimization problems.
When two forms of hydrogen smash together an unusual process called quantum tunnelling can occur. Researchers have now worked out how rarely it happens.
While tunneling reactions are remarkably hard to predict, a group of researchers were able to experimentally observe such an effect, marking a breakthrough in the field of quantum chemistry.
