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

I keep coming back to a strange idea: what if everything we know about quantum physics is already encoded inside a single atom? Not in a mystical sense, but in the very real way that one tiny system ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

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.

With utmost precision: Using special nanographene molecules, the researchers were able to realize a theoretical model from quantum physics. The smallest unit of information in a computer is the bit: ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

Quantum phase transitions (QPTs) represent fundamental shifts in the ground state properties of a system driven by quantum fluctuations rather than thermal effects. The quantum Rabi model, which ...

An international collaboration sheds new light on the relationship between quantum theory and thermodynamics. The research group demonstrated that while the laws of quantum theory alone do not ...

Physicists are now using a tightly controlled laser and a cloud of ultracold atoms to imitate the behavior of electrons in solids, effectively building a quantum version of electronics out of light ...

ONE snowy day last year, I trekked out of Vienna, Austria, winding my way to one of the city’s graveyards to visit the final resting place of a giant of 19th-century physics. Ludwig Boltzmann’s ...

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