Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

The year 2025 marks the 100th anniversary of the birth of quantum mechanics. In the century since the field’s inception, scientists and engineers have used quantum mechanics to create technologies ...

Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...

A team of theoretical researchers used thermal effective theory to demonstrate that quantum entanglement follows universal rules across all dimensions. Their study was published online on August 5, in ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

A South Korean physicist has proposed a theoretical framework that could support the unification of quantum mechanics and the ...

The nature of quantum entanglement remains an outstanding problem in physics. But Albert Einstein's theories, along with insights from quantum computing, could finally put the mystery to rest. When ...

Abstract The theory of quantum states over time extends the density operator formalism into the temporal domain, providing a unified treatment of ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

We’ve had quantum science on our minds all year long, courtesy of 2025 being UNESCO’s International Year of Quantum Science ...
