Reduced phase error through optimized control of a superconducting qubit
Reduced phase error through optimized control of a superconducting qubit
Minimizing phase and other errors in experimental quantum gates allows higher fidelity quantum processing. To quantify and correct for phase errors, in particular, we have developed an experimental metrology---amplified phase error (APE) pulses---that amplifies and helps identify phase errors in general multilevel qubit architectures. In order to correct for both …
