Causal Relations Among N Variables

By combining experimental interventions with search procedures for graphical causal models we show that under familiar assumptions, with perfect data, N − 1 experiments suffice to determine the causal relations among N > 2 variables when each experiment randomizes at most one variable. We show the same bound holds for adaptive learners, but does not hold for N > 4 when each experiment can simul...

Sum uncertainty relations for arbitrary N incompatible observables

We formulate uncertainty relations for arbitrary N observables. Two uncertainty inequalities are presented in terms of the sum of variances and standard deviations, respectively. The lower bounds of the corresponding sum uncertainty relations are explicitly derived. These bounds are shown to be tighter than the ones such as derived from the uncertainty inequality for two observables [Phys. Rev....

Continuous quantum states, Particle on a line and Uncertainty relations

So far we have considered k-level (discrete) quantum systems. Now we turn our attention to continuous quantum systems, such as a particle on a line, which can be in any of an infinite number of classical states. The quantum state of this system is a superposition over all possible positions of the particle. Let us denote by ψ(x) the amplitude with which the particle is at point x. We want ψ to ...

Multimode uncertainty relations and separability of continuous variable states.

A multimode uncertainty relation (generalizing the Robertson-Schrödinger relation) is derived as a necessary constraint on the second moments of n pairs of canonical operators. In turn, necessary conditions for the separability of multimode continuous variable states under (m+n)-mode bipartitions are derived from the uncertainty relation. These conditions are proven to be necessary and sufficie...

Suffice to Determine the Causal Relations Among N Variables

By combining experimental interventions with search procedures for graphical causal models we show that under familiar assumptions, with perfect data, N 1 experiments suffice to determine the causal relations among N>2 variables when each experiment randomizes at most one variable. We show the same bound holds for adaptive learners, but does not hold for N > 4 when each experiment can simultane...
