Query: Toffoli gate based on three-body fine-state changing F\"{o}rster
  resonance in Rydberg atoms   We have developed an improved scheme of a three-qubit Toffoli gate based on
fine-state changing three-body Stark-tuned Rydberg interaction. This scheme is
a substantial improvement of our previous proposal, published in [I.I.Beterov
et al., Physical Review A 98, 042704 (2018)]. Due to the use of a different
type of three-body F\"{o}rster resonance we substantially simplified the scheme
of laser excitation and phase dynamics of collective three-body states. This
new type of F\"{o}rster resonance exists only in three-body systems, while the
two-body resonance is absent. We reduced the sensitivity of the gate fidelity
to fluctuations of external electric field and eliminated the necessity to use
external magnetic field for fine tuning of the position of the resonance in the
electric field scale, compared to the previous scheme of Toffoli gate based on
Rydberg atoms. A gate fidelity of 98.5% was demonstrated in the calculations.
