Description
This talk will summarize recent developments towards the realization of a universal integrated two-qubit quantum computation register for a register-based ion-trap quantum processor. We demonstrated high-fideltiy integrated two-qubit microwave quantum gates with infidelities approach 10-3. Through tailored pulse envelopes, we can suppress the sensitivity to the thus-far dominant source of gate errors - uncontrolled changes in motional mode frequency - by up to two orders of magnitude. We report on the implementation of individual-ion addressing and our current plans for extension to a prototype processor with separate storage, computation and detection registers.
