Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

The nature of gravity — and whether it can be reconciled with quantum mechanics — is one of the biggest mysteries in physics. Most researchers think that at a fundamental level, all phenomena follow ...

Clarke, Devoret, and Martinis win 2025 Nobel Physics Prize for making quantum mechanics tangible. They showed quantum tunneling and energy quantisation in superconducting circuits. Prize marks quantum ...

The possibility of exploiting entanglement in heavy fermion systems for quantum computing has become increasingly attractive. Unlike conventional qubit platforms such as superconducting circuits or ...

Quantum entanglement is incredibly difficult to understand, even scientists, but a new study shows it follows the same basic playbook no matter how many dimensions you consider. The authors used a ...

We develop constrained nuclear-electronic orbital density functional theory (CNEO–DFT) with periodic boundary conditions, enabling simultaneous quantum mechanical treatment of both electrons and ...

Quantum field theory (QFT) is a physics framework that describes how particles and forces behave based on principles rooted in quantum mechanics and Albert Einstein's special relativity theory. This ...

Add a description, image, and links to the quantum-chronotension-field-theory topic page so that developers can more easily learn about it.

A new study reveals that quantum networks can do more than secure communication, they can also test how quantum mechanics behaves in the warped spacetime described by Einstein’s theory of gravity.

Subatomic particles such as quarks can pair up when linked by ‘strings’ of force fields — and release energy when the strings are pulled to the point of breaking. Two teams of physicists have now used ...
