Quantum computers hold the promise to solve certain problems exponentially faster than their classical counterparts. Trapped atomic ions are among the physical systems in which building such a computing device seems viable. In this work we present a

Controlling two-dimensional Coulomb crystals of more than 100 ions in a monolithic radio-frequency trap
Autor: Dominik Kiesenhofer, Helene Hainzer, Artem Zhdanov, Philip C. Holz, Matthias Bock, Tuomas Ollikainen, Christian F. Roos
Linear strings of trapped atomic ions held in radio-frequency (rf) traps constitute one of the leading platforms for quantum simulation experiments, allowing for the investigation of interacting quantum matter. However, linear ion strings have drawba

Experimental observation of thermalization with noncommuting charges
Autor: Florian Kranzl, Aleksander Lasek, Manoj K. Joshi, Amir Kalev, Rainer Blatt, Christian F. Roos, Nicole Yunger Halpern
Quantum simulators have recently enabled experimental observations of quantum many-body systems' internal thermalization. Often, the global energy and particle number are conserved, and the system is prepared with a well-defined particle number - in

Controlling long ion strings for quantum simulation and precision measurements
Autor: Florian Kranzl, Manoj K. Joshi, Christine Maier, Tiff Brydges, Johannes Franke, Rainer Blatt, Christian F. Roos
Scaling a trapped-ion based quantum simulator to a large number of ions creates a fully-controllable quantum system that becomes inaccessible to numerical methods. When highly anisotropic trapping potentials are used to confine the ions in the form o

The conventional approach to perform two-qubit gate operations in trapped ions relies on exciting the ions on motional sidebands with laser light, which is an inherently slow process. One way to implement a fast entangling-gate

In ergodic many-body quantum systems, locally encoded quantum information becomes, in the course of time evolution, inaccessible to local measurements. This concept of "scrambling" is currently of intense research interest, entailing a deep understan

Environment-Assisted Quantum Transport in a 10-qubit Network
Autor: Petar Jurcevic, Philipp Hauke, Tiff Brydges, Rainer Blatt, Nils Trautmann, Christine Maier, B. P. Lanyon, Christian F. Roos, Cornelius Hempel
Publikováno v: Physical review letters. 122(5)
The way in which energy is transported through an interacting system governs fundamental properties in many areas of physics, chemistry, and biology. Remarkably, environmental noise can enhance the transport, an effect known as environment-assisted q

An entropic look into entanglement Quantum systems are predicted to be better at information processing than their classical counterparts, and quantum entanglement is key to this superior performance. But how does one gauge the degree of entanglement
