Ancilla-free measurement of out-of-time-ordered correlation functions: General measurement protocol and Rydberg atom implementation Open
We introduce a protocol that gives access to out-of-time-ordered correlation functions in many-body quantum systems. Unlike other such protocols, our proposal, which can be applied to arbitrary initial states, neither requires ancilla degr…

Analog quantum simulations with Rydberg atoms in optical tweezers routinely address strongly correlated many-body problems due to the hardware-efficient implementation of the Hamiltonian. Yet, their generality is limited, and flexible Hami…

Blackbody-radiation-induced facilitated excitation of Rydberg atoms in optical tweezers Open
Black-body radiation, omnipresent at room temperature, couples nearby Rydberg\nstates. The resulting state mixture features strong dipolar interactions, which\nmay induce dephasing in a Rydberg many-body system. Here we report on a single\…

Motion assisted facilitated excitation of Rydberg atoms in optical tweezers Open
Rydberg atoms feature extremely strong interactions, in particular between states of opposite electronic parity. In a room temperature environment, these states are inevitably populated due to black-body radiation, leading to many-body dep…
