How confused can an entanglement witness be to be still persuasive
Jan Roik, Karol Bartkiewicz, Antonín Černoch +1
Detection of entangled states is essential in both fundamental and applied quantum physics. However, this task proves to be challenging especially for general quantum states. One c…

Interplay between strong and weak measurement: Comparison of three experimental approaches to weak value estimation
Jan Roik, Karel Lemr, Antonín Černoch +1
Weak values are traditionally obtained using a weak interaction between the measured system and a pointer state. It has, however, been pointed out that weak coupling can be replace…
