Olival Freire Jr is a professor of physics and the history of physics at the Federal University of Bahia, Brazil. What makes matter stable? Why are atoms as they are? Why do different materials vary ...

The mere mention of “quantum consciousness” makes most physicists cringe, as the phrase seems to evoke the vague, insipid musings of a New Age guru. But if a new hypothesis proves to be correct, ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

The International Year of Quantum Science and Technology (IYQ) aims to expand public understanding of quantum technologies, including their transformative potential. For our broad readership, could ...

Quantum entanglement is one of the strangest and most fascinating phenomena in physics. Even Einstein didn’t believe it - he called it “spooky action at a distance” - but science has proven it true.

Quantum technology can process an enormous amount of data and solve complex problems in seconds rather than decades. Remarkably, quantum technology first appeared in the early 1900s. It originated ...

Four decades ago, physicists were theorizing that the mind-bending mechanics of quantum physics could be harnessed to make a new kind of computer that’s exponentially more powerful than conventional ...

Quantum computing is one of those technologies where real-world applications always seem to lie just over the horizon. The next big thing is announced before quickly becoming a forgotten article from ...
