A small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum ...

The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the ...

Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

The Signal Insight “You don’t have to understand quantum mechanics to understand the impact of what we do,” Niccolo de Masi ...

For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible fabric that bends but never breaks. A new wave of theories is now challenging ...

Modern physics suggests distance may emerge from motion, gravity and quantum entanglement, not exist as a basic fact. (CREDIT: NASA, ESA, Z. Levay and R. van der Marel/STScI, T. Hallas, and A.

Scientists are exploring a revolutionary theory that suggests human consciousness might operate as a quantum hologram, potentially extending across space and time. This concept, which integrates ...

Quantum gravity seeks a consistent framework to merge the principles of quantum mechanics with general relativity, addressing the challenges of formulating a quantum field theory for the gravitational ...

Mean-field theory and semiclassical methods constitute vital frameworks in contemporary quantum mechanics. By replacing the intricate web of particle interactions with an average or “mean” field, mean ...

Columnist Natalie Wolchover examines the latest developments in the “forever war” over whether string theory can describe the ...
