Group-theoretical analysis of quantum complexity: the oscillator group case
K. Andrzejewski, K. Bolonek-Lasoń, P. Kosiński
Motivated by the recent rapid development of complexity theory applied to quantum mechanical processes we present the complete derivation of Nielsen's complexity of unitaries belon…

The area and volume laws for entanglement of scalar fields in flat and cosmological spacetimes
K. Andrzejewski
We study the area and volume laws for entanglement of free quantum scalar fields. In addition to the entropy, we use the notion of the capacity of entanglement, which measures entr…
