Cauchy-Schwarz inequality and particle entanglement
T. Wasak, P. Szankowski, P. Zin +2
The Glauber-Sudarshan -representation is used in quantum optics to distinguish between semi-classical and genuinely quantum electromagnetic fields. We employ the analog of the $…
Bogoliubov theory for atom scattering into separate regions
T. Wasak, P. Szankowski, R. Bücker +2
We review the Bogoliubov theory in the context of recent experiments, where atoms are scattered from a Bose-Einstein Condensate into two well-separated regions. We find the full dy…
Optimal measurements in phase estimation: simple examples
T. Wasak, J. Chwedenczuk, L. Pezze +1
We identify optimal measurement strategies for phase estimation in different scenarios. For pure states of a single qubit, we show that optimal measurements form a broad set parame…
Tradeoffs for number-squeezing in collisions of Bose-Einstein condensates
P. Deuar, T. Wasak, P. Zin +2
We investigate the factors that influence the usefulness of supersonic collisions of Bose-Einstein condensates as a potential source of entangled atomic pairs by analyzing the redu…
