Quantum space and time Physicists have developed no-go theorems that limit quantum processes in space–time causality. (Courtesy: iStock/piranka) Physicists have developed a new theoretical framework ...

Quantum mechanics wreaks even more havoc with conventional ideas of causality than some have suspected – according to a team of researchers based in Australia, with collaborators in Scotland and ...

Alice and Bob, the stars of so many thought experiments, are cooking dinner when mishaps ensue. Alice accidentally drops a plate; the sound startles Bob, who burns himself on the stove and cries out.

Contrary to the statistician's slogan, in the quantum world, certain kinds of correlations do imply causation. New research shows that in quantum mechanics, certain kinds of observations will let you ...

Quantum batteries could charge more efficiently by skirting conventional rules of causality. Yuanbo Chen at the University of Tokyo and his colleagues analysed whether a particularly counterintuitive ...

BREAKFAST in my house is a causal affair. The kettle boils because I have switched it on. The toast acquires its golden crust because I put it in the toaster. The butter makes its way to the table ...

As I discussed in a recent column, it seems we still have quite a lot to learn about how a causal influence of one thing on another might show up in empirical data. Other aspects of our thinking about ...
