New Advances Bring the Age of Quantum Computing Closer Than Ever | Quanta Magazine

A smiling man wearing round glasses and a light blue sweater, photographed in front of a dark frame window.

In a white paper written on the same day as the Caltech paper, Gidney and his colleagues announced that they had developed a new method for breaking ECC that was at least 10 times more efficient than previous methods. They estimate that most cryptocurrencies would provide seconds to a machine with less than 500,000 qubits. … Read more

The success of US fusion breaks the mystery of decades of heat in tokamaks

The Blueprint

New research at the Princeton Plasma Physics Laboratory (PPPL) has shown that the rotation of the plasma core is a key factor in how particles are distributed within a fusion reactor system. The study shows why plasma particles hit some parts of the reactor more than others. This finding allows computer simulations to match experimental … Read more

Physicists are proposing a modification of Einstein’s relativity that could change our understanding of the Big Bang.

The two dark black holes are surrounded by waves of blue light that melt and twist, all toward the starry foreground.

The Big Bang is often described as the moment when everything began – the point of infinite density where the laws of physics were broken. But what if that picture isn’t perfect? A new study presents a different account of the birth of the universe: Instead of a sudden start from singularity, as predicted by … Read more

Physicists are proposing a modification of Einstein’s relativity that could change our understanding of the Big Bang.

The image of the Big Bang, with its purple, blue and yellow color spread out from a bright white light with vertical rays coming from all directions, all over a black starry sky.

The proposed changes to Einstein’s relativity suggest that the universe did not begin in a single state, which could solve one of the most prominent questions about the Big … Read more

Sir Anthony Leggett obituary: theoretical physicist

Tony Leggett lecturing on Schrödinger's cat at the Loomis Laboratory, University of Illinois Urbana-Champaign, circa 1985.

Anthony Leggett not only made a name for himself as a pioneering academic physicist but in 2003 he shared the Nobel Prize in physics for his research on superfluidity and the theory of superfluidity. However, he had left science at school as something “incomprehensible” – especially physics, which “knows in one ear and out the … Read more

Physicists Discover Something That Can Travel Faster Than Light: The Darkness Inside It

YouTube Thumbnail

For the first time, physicists have discovered that ‘holes’ of light can travel faster than light itself. They are known as phase singularities or optical vortices, and since the 1970s, scientists have predicted that, just as the eddies in the river can move faster than the water flowing around them, so can the waves of … Read more

Discovery of Rare Gravitational Wave May Hold Key to First Evidence of Primordial Black Holes

Primordial Black Holes Natu 940x529

researchers may have found the first direct evidence of ancient black holes, which could revolutionize our understanding of dark matter. A gravitational wave, captured by LIGO in November 2025proposed a revolutionary hypothesis: the collision that produced the signal may not have involved ordinary black holes in stars, but rather black holes formed in the early … Read more

Why do Supermassive Black Holes grow so slowly?

This artist's drawing shows a black hole surrounded by a ring of accretion. When the material inside these rings heats up they emit x-rays. Observing these x-rays is an important part of measuring SMBH and AGN. In this simulation, SMBH also launches a jet. Image credit: NASA/JPL-Caltech

When our powerful infrared telescopes allowed astronomers to look further into the future, they made some amazing discoveries. One of them involves supermassive black holes (SMBH), the physics-defying behemoths at the center of massive galaxies such as the Milky Way. In fact, the SMBH grew much faster in the jewelry world than it does in … Read more

Light can travel for billions of years but it has no time

Light can travel for billions of years but it has no time

A photon from a star billions of light-years away takes no time to reach a telescope. It’s not too little time. There is nothing. That result is not a measured or poetic way of speaking. It comes directly from the mathematics of special relativity, and it points to another strange thing about the nature of … Read more
