…quantum features over surprisingly long time scales. Remarkably, certain quantum states yield higher efficiency than allowed by the Carnot bound, yet in full compliance with the second law of thermodynamics….
Entanglement can enhance the coherent interaction of light and matter at a quantum interface, enabling information transfer within future quantum networks. Here, our interface consists of calcium ions trapped within…
…more than 13000 particles. We use this resource and combined this with swapping the squeezing to magnetically sensitive states for demonstration of quantum enhanced magnetometry with high spatial resolution [2]….
…component: they behave as quantum fluids of light, and show fascinating phenomena like superfluidity, nucleation of topological excitations such as quantized vortices… Patterning of semiconductor microcavities on a micron scale…
The generation of narrow-band, coherent light is significantly easier in some parts of the electromagnetic spectrum than others. Since it is the type of light used for laser cooling and…
The development of optical lattices that imprint artificial gauge fields now allows the creation of energy bands for cold atoms with non-trivial topological character, as encoded in a non-zero Chern…
