Abstract: Black holes provide a window into quantum gravity through their thermodynamic properties. Recently, it has been discovered that higher topology solutions provide additional information about the UV and play an essential role in its consistency. I will discuss how these solutions are used to study statistical properties of the quantum theory, and describe the example of thin-shell wormholes, which are used to understand the coarse-grained entropy of black holes formed by gravitational collapse.

Abstract: Quantum-based electronics is a rapidly accelerating technology, where information is encoded in the quantum mechanical states of coupled natural or artificial atoms. To unlock the exceptional potential of quantum computers, one of the key challenges that the field has to overcome is to preserve the coherence of a quantum superposition over extended times.

Abstract:  Quantum metrology makes use of structured entanglement to perform measurements with greater precision than would be possible with only classically correlated particles. A paradigmatic example of such entanglement is spin squeezing, which is known to be dynamically generated by the celebrated one-axis-twisting model, corresponding to an all-to-all coupled Ising Hamiltonian.

Abstract:

Abstract: For a many-body local Hamiltonian H_0 perturbed by local V [H=H_0+V], one hopes in many scenarios that certain local properties of H_0 persist despite the fact that the extensive V strongly mixes the global eigenstates.
