Abstract: 

I will overview the on-going research of matter-wave solitons in dilute atomic gases. After a brief discussion of the experimental status and basic theory, I shall concentrate on quantum mechanical properties of these objects, namely on creation of quantum superposition and entangled states via scattering of solitons off the potential barrier. I will compare between quantum and mean-field descriptions of the system and will consider the possibility to distinguish these states from the classical statisitical mixtures.
