A new technique sees two distinct particles of light enter a chip and two identical twin particles of light leave it. The image artistically combines the journey of twin particles of light along the outer edge of a checkerboard of rings with the abstract shape of its topological underpinnings.

The Secrets Atoms Hold, Part 2: Gravity

Researchers have engineered a cloud of atoms (blue circles) to create exotic interactions that selectively whittle down a beam of light made of bunches of one, two or three photons (red circles). In the animation above, the ideal case is presented: All groups of three photons interact with each other and are knocked out of the beam, while the smaller bunches pass through unaffected.

A Frankenstein of Order and Chaos

On the left is a representation of a grid of heptagons in a hyperbolic space. To fit the uniform hyperbolic grid into “flat” space, the size and shape of the heptagons are distorted. In the appropriate hyperbolic space, each heptagon would have an identical shape and size, instead of getting smaller and more distorted toward the edges. On the right is a circuit that simulates a similar hyperbolic grid by directing microwaves through a maze of zig-zagging superconducting resonators. (Credit: Springer Nature)
