Researchers show that a single photon can transfer an excitation from a quantum dot to an ion.
A twist on an established imaging method has detected a molecule’s short-lived, excited state, raising the possibility of movies of chemical reactions.
An atom interferometer embedded in an optical cavity requires less power compared to previous techniques and may work with a wider variety of atoms and molecules.
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.
An improved cold atom gyroscope could lead to portable, ultraprecise devices for navigation and tests of fundamental physics.
By measuring gravity with cold atoms at three different heights simultaneously, a team determined a new property of a gravitational field.
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.
