The chopped random basis (CRAB) ansatz for quantum optimal control has been proven to
be a versatile tool to enable quantum technology applications such as quantum computing …

Currently, perovskite solar cells (PSCs) with high performances greater than 20% contain
bromine (Br), causing a suboptimal bandgap, and the thermally unstable methylammonium …

Quantum entanglement involving coherent superpositions of macroscopically distinct states
is among the most striking features of quantum theory, but its realization is challenging …

Tailored quantum states of light can be created via a transfer of collective quantum states of
matter to light modes. Such collective quantum states emerge in interacting many-body …

In the last years, a number of theoretical and numerical tools have been developed by a
thriving community formed by people coming from different backgrounds—condensed …

The observation of strongly interacting many-body phenomena in atomic gases typically
requires ultracold samples. Here we show that the strong interaction potentials between …

In quantum optimal control theory the success of an optimization algorithm is highly
influenced by how the figure of merit to be optimized behaves as a function of the control …

We study the relations between classical information and the feasibility of accurate
manipulation of quantum system dynamics. We show that if an efficient classical …

Bound states of electron–hole pairs in semiconductors demonstrate a hydrogen-like
behavior in their high-lying excited states that are also known as Rydberg exciton states …

We show that two photons coupled to Rydberg states via electromagnetically induced
transparency can interact via an effective Coulomb potential. This interaction gives rise to a …
