We propose novel quantum molecular systems for applications in quantum simulations, computations, and sensing. We investigate two architectures based on ultracold highly magnetic and polar molecules trapped in a harmonic trap or optical lattice, on one hand, and on polar molecular ions forming Coulomb crystal trapped in a linear Paul trap, on the other hand. For both systems we investigate geometries, interactions, quantum many-body phases, time-dependent dynamics, and possible control schemes with external laser, microwave, magnetic, and electric fields. We propose the quantum simulations of novel few- and many-body quantum phenomena, the feasible implementation schemes of one- and two-qubit quantum gates for quantum computations with molecular rovibrational states serving as qubits, and applications of engineered quantum devices for quantum sensing.
