Query: Enhanced-Fidelity Ultrafast Geometric Quantum Computation Using Strong
  Classical Drives   We propose a general approach to implement nonadiabatic geometric single- and
two-qubit gates beyond the rotating wave approximation (RWA). This protocol is
compatible with most optimal control methods used in previous RWA protocols;
thus, it is as robust as (or even more robust than) the RWA protocols. Using
counter-rotating effects allows us to apply strong drives. Therefore, we can
improve the gate speed by 5--10 times compared to the RWA counterpart for
implementing high-fidelity ($\geq 99.99\%$) gates. Such an ultrafast evolution
(nanoseconds, even picoseconds) significantly reduces the influence of
decoherence (e.g., the qubit dissipation and dephasing). Moreover, because the
counter-rotating effects no longer induce gate infidelities (in both the weak
and strong driving regimes), we can achieve a higher fidelity compared to the
RWA protocols. Therefore, in the presence of decoherence, one can implement
ultrafast geometric quantum gates with $\geq 99\%$ fidelities.
