Sensitivity versus selectivity in entanglement detection via collective witnesses
Vojtěch Trávníček, Jan Roik, Karol Bartkiewicz +3
In this paper, we present a supervised learning technique that utilizes artificial neural networks to design new collective entanglement witnesses for two-qubit and qubit-qutrit sy…
Entanglement quantification from collective measurements processed by machine learning
Jan Roik, Karol Bartkiewicz, Antonín Černoch +1
In this paper, we investigate how to reduce the number of measurement configurations needed for sufficiently precise entanglement quantification. Instead of analytical formulae, we…
Synergic quantum generative machine learning
Karol Bartkiewicz, Patrycja Tulewicz, Jan Roik +1
We introduce a new approach towards generative quantum machine learning significantly reducing the number of hyperparameters and report on a proof-of-principle experiment demonstra…
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…
