Publication: Optimizing Rydberg gates for logical qubit performance

Robust gate sequences are widely used to reduce the sensitivity of gate operations to experimental imperfections. Typically, the optimization minimizes the average gate error, however, recent work in quantum error correction has demonstrated that the performance of encoded logical qubits is sensitive to not only the average error rate, but also the type of errors …

Publication: Robust phase-controlled gates for scalable atomic quantum processors

QPerfect researchers have put forward a simple scheme for realizing robust optically controlled quantum gates for scalable atomic quantum processors by driving the qubits with optical standing waves. Compared to existing strategies based on travelling wave lasers, atoms localized close to the antinodes of an optical standing wave can be made to realize phase-controlled quantum …
