Fast Optomechanical Photon Blockade
Yuxun Ling, Sofia Qvarfort, Florian Mintert
The photon blockade effect is commonly exploited in the development of single-photon sources. While the photon blockade effect could be used to prepare high-fidelity single-photon…
Solving quantum dynamics with a Lie algebra decoupling method
Sofia Qvarfort, Igor Pikovski
At the heart of quantum technology development is the control of quantum systems at the level of individual quanta. Mathematically, this is realised through the study of Hamiltonia…
Optimal estimation of time-dependent gravitational fields with quantum optomechanical systems
Sofia Qvarfort, A. Douglas K. Plato, David Edward Bruschi +4
We study the fundamental sensitivity that can be achieved with an ideal optomechanical system in the nonlinear regime for measurements of time-dependent gravitational fields. Using…
Quantum metrology with optomechanical systems in the nonlinear regime
Sofia Qvarfort
This thesis focuses on the mathematical description and application of nonlinear cavity optomechanical systems. The first part is concerned with solving the dynamics of the standar…
Hydrogenic entanglement
Sofia Qvarfort, Sougato Bose, Alessio Serafini
Is there any entanglement in the simplest ubiquitous bound system? We study the solutions to the time-independent Schrödinger equation for a Hydrogenic system and devise two entang…
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…
