Thulium atom as new platform for quantum simulations and quantum information

Summary form only given. Laser cooling and trapping became powerful tool enabling number of research activities and applications such as quantum simulation [1], quantum information processing [2], control of light propagation and switching of optical pulses [3] including single photon gates [4], metrology and testing drift of fundamental constants [5]. Recently rare earth elements attracted considerable attention due to the high orbital and magnetic moments. Such a systems allow low-field Feshabach resonances [6] enabling tunable in wide range interactions, relatively large dipole-dipole interactions. In particular, thulium atom has one hole in 4f shell therefore having orbital moment of 3 in the ground state, magnetic moment of 4 Bohr magnetons in ground state. While magnetic moment of the thulium atom is less than that of Erbium or Dysprosium [7, 8] simpler level structure, possibility to capture thulium atoms and the dipole trap at 532nm [9] make thulium atom an extremely attractive subject for quantum simulations and quantum information processing. In this contribution, I will present our efforts toward brining thulium atom to ultracold temperatures and quantum degeneracy as well as our study of collisional proprieties of thulium atom.
