Tuesday, February 26, 2013 Lessons learned and potential solutions • GRAPE pulses can work in superconducting qubits, but don‘t right now • Precise system characteriz<strong>at</strong>ion is crucial, robust GRAPE does not suffice (yet) • Nonlinear transfer functions limiting factor So we work on these issues 31
