Spectroscopy of interacting quasiparticles

Magnetic interactions engineered by dressing a string of trapped ions with laser light can be described in terms of interacting quasiparticles. Our paper describing many-body Ramsey spectroscopy of these quasiparticles has been published by Physical Review Letters.

Improved interface for a quantum internet

A quantum network requires efficient interfaces over which information can be transferred from matter to light and back. In the current issue of Physical Review Letters, Innsbruck physicists led by Rainer Blatt and Tracy Northup show how this information transfer can be optimized by taking advantage of a collective quantum phenomenon.

Quasiparticle engineering and entanglement propagation

The investigation of the properties of interacting quantum many-body systems is of central importance for condensed matter physics, quantum chemistry, atomic and molecular physics, and related fields. A long-standing challenge in these areas of quantum physics has been the engineering and control of quantum many-body systems with precisely tailored properties. Thanks to an exciting technological development over recent years, systems like neutral atoms, trapped ions, or photons interacting with atomic ensembles are now being used to artificially engineer such quantum matter.

Quantum computation: Fragile yet error-free

In a close collaborative effort, Spanish and Austrian physicists have experimentally encoded one quantum bit (qubit) in entangled states distributed over several particles and for the first time carried out simple computations on it. The 7-qubit quantum register could be used as the main building block for a quantum computer that corrects any type of error. The researchers’ results have now been published in Science.
