Quantum controlled-logic gates, including controlled not gate and Toffoli gate, play critical
roles in lots of quantum information processing schemes. We design and experimentally …

Nonlocal observables of spacelike separated quantum systems in combination with their
measurements contribute greatly to quantum theory and its applications. We present a …

Abstract Einstein–Podolsky–Rosen (EPR) steering is commonly shared among multiple
observers by utilizing unsharp measurements. Nevertheless, their usage is restricted to local …

In this work, the measurement transition as well as precision measurement advantages of
single-photon-added coherent state after postselected von Neumann measurement are …

In general, the state of a quantum system represented by the density operator and its
determination is a fundamental problem in quantum theory. In this study, two theoretical …

Measuring a nonlocal observable on a space-like separated quantum system is a resource-
hungry and experimentally challenging task. Several theoretical measurement schemes …

Instantaneous two-party quantum computation is a computation process in which there are
initial shared entanglement, and the nonlocal interactions are limited to simultaneous …

This thesis details two experiments and one theoretical manuscript that explore the nature of
measurement disturbance in quantum mechanics. The first experiment exploits …

The direct measurement of nonlocal properties of entangled quantum systems has been the
subject of several recent experimental investigations. Of particular interest is the …
