Researchers demonstrate first terahertz quantum sensing

Quantum physicists rely on quantum sensing as a highly attractive method to access spectral regions and detect photons (tiny packets of light) that are generally technically challenging. They can gather sample information ...

Cooling magnets with sound

Today, most quantum experiments are carried out with the help of light, including those in nanomechanics, in which tiny objects are cooled with electromagnetic waves to such an extent that they reveal quantum properties. ...

Deconstructing Schrödinger's cat

The paradox of Schrödinger's cat—the feline that is, famously, both alive and dead until its box is opened—is the most widely known example of a recurrent problem in quantum mechanics: its dynamics seem to predict that ...

Laser physics: At the pulse of a light wave

Physicists in the Laboratory for Attosecond Physics at Ludwig-Maximilians-Universitaet (LMU) in Munich and at the Max Planck Institute for Quantum Optics (MPQ) have developed a novel type of detector that enables the oscillation ...

Quantum material goes where none have gone before

Rice University physicist Qimiao Si began mapping quantum criticality more than a decade ago, and he's finally found a traveler that can traverse the final frontier.
