On the structure of mirrored operators obtained from optimal entanglement witnesses
Anindita Bera, Joonwoo Bae, Beatrix C. Hiesmayr +1
Entanglement witnesses (EWs) are a versatile tool in the verification of entangled states. The framework of mirrored EW doubles the power of a given EW by introducing its twin -- a…
Is bound entanglement Lorentz invariant?
Paweł Caban, Beatrix C. Hiesmayr
Bound entanglement, in contrast to free entanglement, cannot be distilled into maximally entangled states by two local observers applying measurements and utilizing classical commu…
A Quantum Information Theoretic View On A Deep Quantum Neural Network
Beatrix C. Hiesmayr
We discuss a quantum version of an artificial deep neural network where the role of neurons is taken over by qubits and the role of weights is played by unitaries. The role of the…
Comparing bound entanglement of bell diagonal pairs of qutrits and ququarts
Christopher Popp, Beatrix C. Hiesmayr
We compare the classification as entangled or separable of Bell diagonal bipartite qudits with positive partial transposition (PPT) and their properties for different dimensions. F…
Almost complete solution for the NP-hard separability problem of Bell diagonal qutrits
Christopher Popp, Beatrix C. Hiesmayr
With a probability of success of we solve the separability problem for Bell diagonal qutrit states with positive partial transposition (PPT). The separability problem, i.e.…
