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 ...

Quantum invariants have emerged as powerful algebraic and numerical tools that encapsulate the subtleties of topological structures. By drawing on quantum group theory and the constructs of ...

New research from Caltech and Oratomic, a Caltech-linked startup, says quantum computers of the future may be closer to reality. Researchers at the California Institute of Technology theorize that a ...

WEST LAFAYETTE, Ind. — Caltech president and pioneering physicist Thomas Rosenbaum, an expert in the promising field of quantum physics, will join Purdue University President Mung Chiang in April for ...

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 ...

This theory implies that all laws of physics are the same, independent of the relative motion between observers—a concept known as Lorentz invariance. Meanwhile, quantum theory has been developed, ...

In the 1960s, a group of physicists and historians began a massive project meant to catalogue and record the history of quantum physics. It was called Sources for History of Quantum Physics (SHQP). As ...

There is no question that quantum theory is correct. It’s been proven over and over, both in the lab and through practical achievement. But the question remains: is it always correct? Quantum ...

Researchers have developed a novel high-energy particle detection instrumentation approach that leverages the power of quantum sensors -- devices capable of precisely detecting single particles. To ...
