Confident entanglement detection via separable numerical range
Timo Simnacher, Jakub Czartowski, Konrad Szymański +1
We investigate the joint (separable) numerical range of multiple measurements, i.e., the regions of expectation values accessible with (separable) quantum states for given observab…
Entanglement in highly symmetric multipartite quantum states
Adam Burchardt, Jakub Czartowski, Karol Życzkowski
We present a construction of genuinely entangled multipartite quantum states based on the group theory. Analyzed states resemble the Dicke states, whereas the interactions occur on…
Perfect quantum-state synchronization
Jakub Czartowski, Ronny Müller, Karol Zyczkowski +1
We investigate the most general mechanisms that lead to perfect synchronization of the quantum states of all subsystems of an open quantum system starting from an arbitrary initial…
