Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction. Yet daily life ...

When humans think about time, most imagine a steady flow of seconds ticking into minutes and minutes into hours which carry us from past to present to future. But in the science of quantum physics, ...

Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a superposition of states—being in multiple places and configurations all at ...
