Problem

Two transmons are coupled with exchange strength J/2π=15.0 MHzJ/2\pi = 15.0\,\mathrm{MHz}, tuned so that the ∣11⟩|11\rangle and ∣02⟩|02\rangle levels are brought near resonance to implement a controlled-phase gate. The gate time is t=π/(2 J)t = \pi/(\sqrt2\,J), with JJ the angular exchange rate. Find the controlled-phase gate time.
