Silica surface features and their role in the adsorption of biomolecules: computational modeling and experiments
There are many reasons to report on silica interacting with biomolecules. The most obvious
one is that on the Earth's crust, oxygen and silicon are the most abundant atomic species …

Unifying scrambling, thermalization and entanglement through measurement of fidelity out-of-time-order correlators in the Dicke model
Scrambling is the process by which information stored in local degrees of freedom spreads
over the many-body degrees of freedom of a quantum system, becoming inaccessible to …

Random unitaries in extremely low depth
We prove that random quantum circuits on any geometry, including a 1D line, can form
approximate unitary designs over $ n $ qubits in $\log n $ depth. In a similar manner, we …
