Researchers generate tunable twin particles of light

Identical twins might seem 'indistinguishable,' but in the quantum world the word takes on a new level of meaning. While identical twins share many traits, the universe treats two indistinguishable quantum particles as intrinsically ...

Researchers in Sweden develop light emitter for quantum circuits

The promise of a quantum internet depends on the complexities of harnessing light to transmit quantum information over fiber optic networks. A potential step forward was reported today by researchers in Sweden who developed ...

Observation of antichiral edge states in a circuit lattice

A modified Haldane lattice exhibits the intriguing phenomenon of antichiral edge states that propagate in the same direction on opposite edges and co-exist with bulk states. Using an electric circuit, researchers have successfully ...

Complex shapes of photons to boost future quantum technologies

As the digital revolution has now become mainstream, quantum computing and quantum communication are rising in the consciousness of the field. The enhanced measurement technologies enabled by quantum phenomena, and the possibility ...

Team makes single photon switch advance

The ability to turn on and off a physical process with just one photon is a fundamental building block for quantum photonic technologies. Realizing this in a chip-scale architecture is important for scalability, which amplifies ...

Steering light to places it isn't supposed to go

Light that is sent into a photonic crystal can't go deeper than the so-called Bragg length. Deeper inside the crystal, light of a certain color range can simply not exist. Still, researchers of the University of Twente, the ...
