Quantum technologies exploit entanglement to enhance various tasks beyond their classical
limits including computation, communication and measurements. Quantum metrology aims …

Continuous phase spaces have become a powerful tool for describing, analyzing, and
tomographically reconstructing quantum states in quantum optics and beyond. A plethora of …

Quantum devices are preparing increasingly more complex entangled quantum states. How
can one effectively study these states in light of their increasing dimensions? Phase spaces …

We present an experimental scanning-based tomography approach for near-term quantum
devices. The underlying method has previously been introduced in an ensemble-based …

We investigate the tomography of unknown unitary quantum processes within the framework
of a finite-dimensional Wigner-type representation. This representation provides a rich …

Phase spaces as given by the Wigner distribution function provide a natural description of
infinite-dimensional quantum systems. They are an important tool in quantum optics and …

Experimental verification of quantum operators plays an essential role in characterizing and
thereby improving the performance of a quantum computer. This thesis provides an …

Conventional computers are invaluable tools for analysing and predicting the behaviour of
the world around us; from the formation of the Universe at large, to the motion of subatomic …
