Higgs excitations near absolute zero

(Phys.org) -- A collaboration of physicists from Max Planck Institute of Quantum Optics, LMU, Harvard and Caltech detect Higgs-type excitations in a low-dimensional system of ultracold atoms at the transition between different ...

Disentangling information from photons

Theoretical physicist Filippo Miatto and colleagues from the University of Strathclyde, Glasgow, UK, have found a new method of reliably assessing the information contained in photon pairs used for applications in cryptography ...

Entanglement study makes a quantum leap

Some scientists have likened it to voodoo, while Albert Einstein called it just plain "spooky." In the bizarre realm of quantum mechanics, entanglement is the phenomenon in which two seemingly distinct particles control each ...

Quantum physics mimics spooky action into the past

Physicists of the group of Prof. Anton Zeilinger at the Institute for Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Vienna Center for Quantum Science and Technology (VCQ) have, for the ...

Single molecules in a quantum movie

The quantum physics of massive particles has intrigued physicists for more than 80 years, since it predicts that even complex particles can exhibit wave-like behaviour – in conflict with our everyday ideas of what is ...

Light pulses take a quantum walk

Tourists who drift aimlessly during a sightseeing tour are moving randomly - just like electrons that move from one atom to the next. To obtain a better understanding of these random motions it is often useful to reduce their ...

A quantum connection between light and motion

(PhysOrg.com) -- Physicists have demonstrated a system in which light is used to control the motion of an object that is large enough to be seen with the naked eye at the level where quantum mechanics governs its behavior.

Speed limit on the quantum highway

(PhysOrg.com) -- Physicists at the Max Planck Institute of Quantum Optics have measured the propagation velocity of quantum signals in a many-body system.
