Quantum computers are both the most promising and the most confusing segment of innovation in computing. On one hand, quantum computers promise to perform calculations that would otherwise be utterly ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

A routine quantum optics technique just revealed an extraordinary secret: entangled light can carry incredibly complex ...

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

The Quantum Systems Accelerator (QSA), a National Quantum Information Science Research Center funded by the U.S. Department of Energy Office of Science, takes a science-first approach to exploring new ...

A single beam of entangled light, generated by equipment found in laboratories around the world, has been concealing one of ...

Physicists have achieved a long-sought goal in demonstrating quantum entanglement using the momentum of atoms, rather than their internal states. Since atoms’ momentum can be affected by gravity, this ...

A team of physics educators is focusing on a new approach to teaching quantum physics in schools. Traditional classroom teaching has tended to focus on presenting the history of the origins of quantum ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

After the passing of physicist Anthony Leggett, columnist Karmela Padavic-Callaghan remembers their personal connection with ...

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