A team led by experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatia…

Unlike the way in which quantum entanglement between clouds of particles has been created up to now, and which involves…

Materials with engineered colorimetric signatures detectable by the naked eye are in high demand for optical sensing and…

The new NIST method generates digital bits with photons, or particles of light, using data generated in an improved vers…

Researchers at the Centre for Quantum Technologies in Singapore propose that lutetium clocks could outperform today's timekeepers

The six-month effort, involving a high-power laser like those used for industrial cutting, gave a result for the blackbo…

A boost for graphene-based light detectors

This simple scenario of light-induced electron heating in graphene can explain many observed effects. Aside from describ…

Experiments with ultra-cold atoms at the TU Wien have shown surprising results: coupled atom clouds synchronize within milliseconds. This effect cannot be explained by standard theories.

When two ultra-cold quantum gases are coupled, they can synchronize spontaneously, oscillating in perfect unison after j…

Light has bidirectional transmission reciprocity in common dielectric material. Breaking this reciprocity in the directi…

For the first time, researchers from UNIGE and MBI in Berlin have placed an electron in a dual state -- neither freed nor bound -- thus confirming a hypothesis from the 1970s

The more intense a laser is, the easier should it be to ionise the atom--in other words, to tear the electrons away from…

Engineers team up to reduce the size, cost and power requirements of an optical frequency device

Optical frequency synthesizers provide unprecedented performance but until now have been large, expensive and power hung…

Two-photon technique more stable than existing one-photon technology

Technique uses photons, fundamental components of light, to measure nanoscopic materials thinner than 100,000th the widt…

Engineering and physics researchers at North Carolina State University have developed a new technology for steering ligh…

The researchers observed that an increase in the laser pumping power triggered nonlinear effects in the system. By incre…

The experiment used lasers to cool atoms to just a few billionths of a degree above absolute zero. At these temperatures…

Researchers of TU Dresden reveal the nature of optical excitations in two-dimensional crystals within an international c…

AMOLF develops a magnet-free optical circulator

Circulators allow to transmit information without loss among more than two nodes in a network, which is why they are alr…

Advancement could streamline and boost scientific research all over the world, help computing industry

To make use of the new coating, a laser is needed. Zhao says a common helium-neon laser, which can be seamlessly integra…

A team of researchers in Germany and at the University of Michigan have demonstrated how infrared laser pulses can shift…

Lenses and mirrors with freeform surfaces enable designers to focus light within optical devices that are lighter, more…

By placing the most magnetic element of the periodic table into a quantum version of a popular desktop toy, Stanford scientists explore the emergence of quantum chaos and thermal equilibrium.

Lev and his group built their own quantum version of Newton’s cradle in order to answer questions about how the chaotic…
