Can you prove whether a large quantum system truly behaves according to the weird and wonderful rules of quantum mechanics—or ...

Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings physicists use to represent particle interactions. The new method has already ...

Enrique Rico Ortega and Sofia Vallecorsa explain how quantum computing will allow physicists to model complex dynamics, from ...

Quantum computing firm Oxford Quantum Circuits (OQC) has released its roadmap, targeting 200 logical qubits by 2028 and 50,000 by 2034. The UK-based company claims it is on track to deliver viable ...

(Feynman diagram calculations rely heavily on perturbation expansions.) This makes the equations much easier to calculate with.
