  Trapping electrons in quantum dots and controlling their collective quantum
states is crucial for converting semiconductor structures into bits of quantum
information processing. Here, we study single- and two-particle states in
quantum dots formed in gapped bilayer graphene (BLG), where the electron's
valley states appear in pair with their spin quantum number and we analyse
spin- and valley-singlet and triplet states for various BLG and dot parameters,
as well as two-particle interaction strength and external magnetic field.
