Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...

Quantum computing is a field of computer science that uses quantum mechanics to solve problems that are too complex for ...

I keep coming back to a strange idea: what if everything we know about quantum physics is already encoded inside a single atom? Not in a mystical sense, but in the very real way that one tiny system ...

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 ...

In the race to uncover the deepest secrets of the universe, researchers are turning to powerful new tools. One of the most promising tools is the quantum computer. It offers a way to explore problems ...

Sorta sparked by this comment someone made to me but it's similar to what other people have told me before: I was listening to a lecture on quantum electrodynamics and it helped me conceptualize the ...

Physicists at the University of Illinois Urbana-Champaign are now testing quantum simulations of these so-called strong-field QED (SFQED) processes, recently translating several processes into the ...

Noncommutative Quantum Field Theory represents an ambitious extension of standard quantum field theory that incorporates a fundamental noncommutativity in the structure of spacetime. In these models, ...

Quantum mechanics would allow the Universe to eventually tunnel to the lowest energy state, or the ‘true’ vacuum, and that process would result in a cataclysmic global event. (CREDIT: Professor Zlatko ...

Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields ...

World Quantum Day highlights the science behind technologies that already power your life and those that could reshape it ...

Ghost Murmur was described as a futuristic CIA tool that could detect a heartbeat from vast distances. Physicists say the public story clashes with the basic limits of magnetic sensing ...
