This computer-generated visualization shows the wavelike pattern of a “quantum handshake” between a hydrogen atom emitting energy and another atom receiving the energy. (J. Cramer and C. Mead via ...

Quantum mechanics, when examined closely, poses some deep questions about reality. These questions often take the form of thought experiments, which are later (usually much later) followed up by real ...

The collapse of the quantum wave function – in which quantum objects go from existing within many possible states at once to settling into a concrete one understood by classical physics – does not ...

The twenty-first century has undoubtedly been the era of quantum science. Quantum mechanics was born in the early twentieth century and has been used to develop unprecedented technologies which ...
