Evading Heisenberg isn't easy

EPFL researchers, with colleagues at the University of Cambridge and IBM Research-Zurich, unravel novel dynamics in the interaction between light and mechanical motion with significant implications for quantum measurements ...

Quantum mechanics: entanglements in ultracold atomic clouds

A system's state is characterised as entangled or quantum correlated if two or more particles cannot be described as a combination of separate, independent states but only as a whole. Researchers at the Kirchhoff Institute ...

Easing uncertainty

Heisenberg's uncertainty principle, the fundamental impossibility of simultaneously measuring properties such as position and momentum, is at the heart of quantum theory. Physicists at ETH Zurich have now demonstrated an ...

Quantum speed limits are not actually quantum

Quantum mechanics has fundamental speed limits—upper bounds on the rate at which quantum systems can evolve. However, two groups working independently have published papers showing for the first time that quantum speed ...

Smart atomic cloud solves Heisenberg's observation problem

Scientists at the University of Copenhagen have developed a hands-on answer to a challenge linked to Heisenberg's Uncertainty Principle. The researchers used laser light to link caesium atoms and a vibrating membrane. The ...
