Squeezed light produced using silicon micromechanical system

One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still. Low levels of noise, known as quantum fluctuations, ...

An ultradilute quantum liquid made from ultra-cold atoms

ICFO researchers created a novel type of liquid 100 million times more dilute than water and 1 million times thinner than air. The experiments, published in Science, exploit a fascinating quantum effect to produce droplets ...

Physicists offer new theory for iron compounds

An international team of physicists from the United States and China this week offered a new theory to both explain and predict the complex quantum behavior of a new class of high-temperature superconductors.

Quantum-limited Measurement Method for Nanosensors

(PhysOrg.com) -- (PhysOrg.com) -- A team of scientists from the Max Planck Institute of Quantum Optics and the Ludwig Maximilians University have succeeded in applying a novel optical method to nano-mechanical oscillators. ...
