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 ...

Trying to solve quantum gravity is frustrating. We have made tremendous progress in quantum theory, but it seems that every ...

This spring marks the end of physics Professor Peter Love’s quantum information and quantum computing lab group’s time at ...

The gravity quantum field is calculated in flat spacetime. The curved classical metric is calculated using the expectation value of the gravity quantum field. At long last, a unified theory combining ...

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.

An international team of researchers has found a simple relationship between the rates of energy and information transmission across an interface connecting two quantum field theories. An ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

A new study links the universe’s expansion to quantum topology, suggesting that hidden mathematical structures may stabilize ...

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can ...

Quantum Electrodynamics (QED) examines the fusion of quantum mechanics and electromagnetism, moving beyond classical theories ...

Does anyone understand quantum theory? The legendary Richard Feynman suggested that if you think you do, you haven’t understood it at all. But quantum theory is our best description of the microscopic ...
