A simple system consisting of a pair of atoms in a two-site “minicrystal” is able to reproduce the physics of a widely used model of electrons in a solid.
A scheme using two pump wavelengths in the infrared and ultraviolet produces more efficient laserlike emission in air, which could benefit remote sensing applications.
A new technique in matter-wave interferometry using laser light to fragment molecules may open the door to interference demonstrations with large bio-molecules or nanoclusters.
Qubits based on trapped ions can be prepared and manipulated with record-breaking accuracy, offering a promising scalable platform for quantum computing.
Researchers characterize a single-photon source, proving it emits nonclassical states of light that may be useful for quantum communication schemes.
Two research groups have engineered an optical lattice of atoms that mimic the behavior of electrons moving in a crystal and a strong magnetic field.
