The consequences of a coherent evolution and its interconnection with quantum jumps are pinpointed, going beyond the master-equation description of open quantum systems. The emphasis laid on individual realizations targets modern experiments on resonance fluorescence, which remains at the core of quantum electrodynamics.

A technique capable of linking global estimations with local estimations is developed. The method is used to reveal the existence of a strict hierarchy of achievable precision for different global estimation strategies and uncover unexpected results contrary to conventional wisdom in local estimations.

For typical waveguide QED systems, it is shown that all time-independent, dissipative, entanglement generation schemes take exponentially long. A rapid, high-fidelity, driven-dissipative scheme based on time-dependent driving is proposed to generate entanglement. The proposed scheme can be applied to generate dimer pairs exponentially quicker than all time-independent schemes in typical waveguide QED systems.

The interplay of integrability and chaos in Shor’s factoring algorithm is explored. It is shown that the periodic modular multiplication component in Shor’s algorithm is, in several cases, a superposition of maximally chaotic quantum maps with the same classical limit.
