Quantum simulations with strongly interacting photons: Simulating exotic phases of matter and applications in quantum technology
Abstract: Classical computers require enormous computing power and memory to simulate even the most modest quantum systems. That makes it difficult to model, for example, why certain materials are in...

How to grab an atom without squeezing it
Abstract: Research for cooling and trapping of atoms in the mid 1980s was mainly motivated to enable precise spectroscopic measurement. However, perturbation by the trapping force introduces sig-nifi...

Quantum stochastic processes: A complete theory for non-Markovian quantum phenomena
Abstract: In science, we often want to characterise dynamical processes to identify the underlying physics and predict the future states of the system. If the state of the system at any time depends ...

Observation of conclusive one-way quantum steering and heralded quantum steering
Abstract: Within the hierarchy of quantum correlations, the Einstein-Podolsky-Rosen steering task (also called quantum steering) is distinguished from both entanglement verification and Bell nonlocal...

Towards an Optical Frequency Standard based on 176Lu+
Abstract: In essence, the accuracy and performance of an atomic clock ultimately depends on various systematic shifts in the narrow-linewidth transition in an isolated atomic system. Lutetium ion pos...

Self-testing using only marginal information
Abstract: Self-testing, aka device-independent tomography, refers to the fact that some quantum states and measurements can be uniquely determined from the observed statistics, without any prior char...
