For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has been a cornerstone of the ...

A photon enters an extraordinarily intense laser field. When it exits, its polarization has rotated, as though empty space ...

A team of physicists has designed quantum algorithms that can model one of the most elusive behaviors in nature: a photon flipping its polarization inside an extreme electromagnetic field. The work, ...

Physicists are using quantum computers to simulate high-intensity electromagnetic interactions to test the limits of light ...

Optical microcavities have emerged as pivotal tools in modern photonics, enabling the manipulation and control of light within minuscule volumes. By confining electromagnetic fields in high‐quality ...

Quantum optics and waveguide quantum electrodynamics represent rapidly evolving frontiers at the intersection of photonics and quantum science. These disciplines explore the fundamental interactions ...

An artist’s impression of a quantum electrodynamics simulation using 100 qubits of an IBM quantum computer. The spheres and lines denote the qubits and connectivity of the IBM quantum processor; gold ...

Vacuum is often thought of as empty, but in fact it is teeming with fleeting energy fluctuations—virtual photons popping in and out of existence that can interact with matter, giving rise to new, ...

Heisenberg’s Uncertainty Principle states that there are limits to how precisely certain pairs of physical properties, like ...

A team of Rice University researchers reported the first direct observation of a surprising quantum phenomenon predicted over half a century ago, opening pathways for revolutionary applications in ...

Taking quantum circuits from a vague academic notion to the factory floor in just over 40 years might sound daunting — even impossible. But as Yale physicist Robert Schoelkopf explains, it all came ...
