Quantum field theory (QFT) provides a comprehensive framework for describing the fundamental interactions of matter and radiation. In the context of atom‐field interactions, QFT elucidates how atoms ...

Researchers find that a photon can spend a negative amount of time in an excited atomic state while passing through a cloud ...

While William Rowan Hamilton isn’t a household name like, say, Einstein or Hawking, he might have been. It turns out the ...

Max Planck is widely recognized as the father of quantum theory for his groundbreaking work on energy quanta. His initial ...

This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum mechanics was proposed. The theory hardly needed the extra publicity, though ...

Not every day does “time” get into misbehavior, but in a new experiment, photons passing through a fog of ultracold rubidium-85 atoms were shown to spend a negative duration in an excited atomic state ...

Physicists have unveiled a new type of time crystal that is governed by quantum behavior that conflicts with classical models ...

Caltech scientists have built a record-breaking array of 6,100 neutral-atom qubits, a critical step toward powerful error-corrected quantum computers. The qubits maintained long-lasting superposition ...

A new calculation shows how five atoms interact in the Efimov effect. It marks a major leap in quantum physics. Matter behaves weirdly at the quantum scale, one of the strangest examples being the ...

World’s Fastest Electron Microscope, Quantum Consciousness and the Origin of Life Host Erika Hamden explores quantum mysteries. We visit a University of Arizona lab where the world’s fastest electron ...

NASA's Cold Atom Lab on board the ISS. NASA/JPL-Caltech NASA is experimenting with the use of quantum technology to measure gravity, magnetic fields, and other forces in space. The space agency just ...
