Optimal estimation with quantum optomechanical systems in the nonlinear regime
Fabienne Schneiter, Sofia Qvarfort, Alessio Serafini +4
We study the fundamental bounds on precision measurements of parameters contained in a time-dependent nonlinear optomechanical Hamiltonian, which includes the nonlinear light-matte…
Time-evolution of nonlinear optomechanical systems: Interplay of mechanical squeezing and non-Gaussianity
Sofia Qvarfort, Alessio Serafini, André Xuereb +3
We solve the time evolution of a nonlinear optomechanical Hamiltonian with arbitrary time-dependent mechanical displacement, mechanical single-mode squeezing and a time-dependent o…
Passively stable distribution of polarisation entanglement over 192 km of deployed optical fibre
Sören Wengerowsky, Siddarth Koduru Joshi, Fabian Steinlechner +14
Quantum key distribution (QKD) based on entangled photon pairs holds the potential for repeater-based quantum networks connecting clients over long distance. We demonstrate long-di…
Chimera states in small disordered optomechanical arrays
Karl Pelka, Vittorio Peano, André Xuereb
Synchronization of weakly-coupled non-linear oscillators is a ubiquitous phenomenon that has been observed across the natural sciences. We study the dynamics of optomechanical arra…
