- Abstract: We show that the rainbow state, which has volume law entanglement entropy for
most choices of bipartitions, can be embedded in a many-body localized
spectrum. For a broad range of disorder strengths in the resulting model, we
numerically find a narrow window of highly entangled states in the spectrum,
embedded in a sea of area law entangled states. The construction hence embeds
mobility edges in many-body localized systems. This can be thought of as the
complement to many-body scars, an `inverted quantum many-body scar', providing
a further type of setting where the eigenstate thermalization hypothesis is
violated.

We study a finite, two-dimensional, disordered model hosting a tower of scar states.
We find numerically that the spectra are nonthermal, and the scar states appear as exact eigenstates with high entropy.
We argue that, for the considered type of models, the localization is stronger than what would be naively expected.

Signatures of localization have been observed in condensed matter and cold atomic systems.
We propose a model of one-dimensional chain of non-interacting, spinless fermions coupled to a local ensemble of baths.
We show that the steady state of the system undergoes a localization entanglement phase transition by tuning $p$ which remains stable in the presence of coherent hopping.

Reservoir engineering is a remarkable task that takes dissipation and decoherence as tools rather than impediments.
We develop a collisional model to implement reservoir engineering for the one-dimensional harmonic motion of a trapped ion.
Having multiple internal levels, we show that multiple reservoirs can be engineered, allowing for more efficient synthesis of well-known non-classical states of motion.

Quantum many-body scars (QMBS) constitute a new quantum dynamical regime in which rare "scarred" eigenstates mediate weak ergodicity breaking.

Purifying entanglement resources after their imperfect generation is an indispensable step towards using them in quantum architectures.
Here we depart from the typical purification paradigm for multipartite states explored in the last twenty years.
We find that smaller sacrificial' states, like Bell pairs, can be more useful in the purification of multipartite states than additional copies of these same states.

We show that a controlled interaction with the environment may help to create a state, dubbed as em dark'', which is immune to decoherence.
To encode quantum information in the dark states, they need to span a space with a dimensionality larger than one, so different states act as a computational basis.
This approach offers new possibilities for storing, protecting and manipulating quantum information in open systems.
