The use of opioid adjuvants in perioperative multimodal analgesia.

Postoperative analgesia plays a crucial role in day-case surgery. Patients expect effective pain relief after surgery, without side effects, and this may not always be possible when more complicated procedures are performed in ambulatory settings. Moreover, both surgeons and patients expect anaesthesiologists to provide an effective pain treatment service especially after ambulatory surgery, ev...

9 v 1 9 N ov 1 99 9 Greenberger - Horne - Zeilinger paradoxes for multiport beam splitters

In a gedankenexperiment N particles in a generalised GHZ-type beam entangled state (each particle can be in one of M beams) are fed into N symmetric 2M-port beam splitters (spatially separated). Correlation functions for such a process (using the Bell numbers value assignment approach) reveal a remarkable symmetry. For N = M + 1 ≥ 4 a series of GHZ paradoxes are shown.

Do all pure entangled states violate Bell's inequalities for correlation functions?

Any pure entangled state of two particles violates a Bell inequality for two-particle correlation functions (Gisin's theorem). We show that there exist pure entangled N>2 qubit states that do not violate any Bell inequality for N particle correlation functions for experiments involving two dichotomic observables per local measuring station. We also find that Mermin-Ardehali-Belinskii-Klyshko in...

An Overview of the Lola System

Bell's theorem for general N-qubit states.

We derive a single general Bell inequality which is a sufficient and necessary condition for the correlation function for N particles to be describable in a local and realistic picture, for the case in which measurements on each particle can be chosen between two arbitrary dichotomic observables. We also derive a necessary and sufficient condition for an arbitrary N-qubit mixed state to violate...
