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 ...

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 ...

A research team has, for the first time in the world, elucidated the microscopic mechanism by which quantum order is lost and collapses in "open quantum environments" existing in nature. Since ...

Quantum mechanics, the theory governing the microscopic world, is famously counterintuitive. A particle can exist in a superposition of multiple states, such as different positions, until a ...

Theoretical physicists studying quantum fields in curved spacetime have built a growing body of calculations showing that ...

The apparent weirdness of the quantum world is often exemplified by the paradox of Schrödinger's imaginary cat that exists in a limbo state of being both alive and dead until looked upon by an ...
