Effects of realistic pulse shapes in two-dimensional spectroscopy
M. Russo, R. Gilliot, A. Blech +3
Two-dimensional (2D) spectroscopy is a powerful pump-pump-probe technique for revealing couplings between quantum states and disentangling the different contributions to the optica…
Detecting entanglement from few partial transpose moments and their decay via weight enumerators
Daniel Miller, Jens Eisert
The -PPT criterion is an experimentally viable relaxation of the well-known positive partial transposition (PPT) criterion for the certification of quantum entanglement. Recen…
Operator spreading in random unitary circuits with orthogonal/symplectic-invariant gate distributions
Zhiyang Tan, Piet W. Brouwer
We investigate operator spreading in random quantum circuits with gates drawn from orthogonal-invariant or symplectic-invariant ensembles, revealing several key distinctions from t…
Open quantum systems beyond equilibrium: Lindblad equation and path integral molecular dynamics
Benedikt M. Reible, Somayeh Ahmadkhani, Luigi Delle Site
The Lindblad equation determines the time evolution of the density operator of open quantum systems. While valid for any system size, its use is, in practice, restricted to prototy…
Rigorous no-go theorems for heralded linear-optical state generation tasks
Deepesh Singh, Ryan J. Marshman, Luis Villegas-Aguilar +2
A major challenge in photonic quantum technologies is developing strategies to prepare suitable discrete-variable quantum states using simple input states, linear optics, and auxil…
Gaussian time-translation covariant operations: structure, implementation, and thermodynamics
Xueyuan Hu, Lea Lautenbacher, Giovanni Spaventa +3
Time-translation symmetry strongly constrains physical dynamics, yet systematic characterization for continuous-variable systems lags behind its discrete-variable counterpart. We c…
