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

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

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

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

Einstein and the Quantum Revolutions Alain Aspect Univ. Chicago Press (2024) French physicist Alain Aspect is a pioneer in ‘quantum entanglement’ — connections between the quantum properties of ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

The original version of this story appeared in Quanta Magazine. In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She ...

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.

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Researchers at Google have used their Willow quantum computer to demonstrate that "quantum contextuality" may be a crucial ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the ...

A recent groundbreaking experiment in which anesthesia was administered to rats has convinced some scientists that tiny structures in the rodents’ brains are responsible for the experience of ...
