There are several ways to describe non-classical phenomena between quantum systems. A famous one is Bell nonlocality, which states that any classical causal model cannot fully explain the statistics between two (or more) quantum systems. One of the most significant applications of Bell nonlocality is that it can be used for verifying properties of quantum systems without any assumptions on the underlying quantum states and measurement devices. This talk will be divided into two parts. In the first part, we will briefly introduce the aforementioned verification, also called “black-box quantum certification”. In the second part, we will present our recent works on quantifying quantum properties in a black-box framework, including the methodology and important results.

Keywords: Bell nonlocality, Bell inequality, quantum entanglement, black-box quantum certification, device-independence
