Webphase errors occur due to ac Stark shifting of the 1↔2 transition [4]. We use the transmon because of its demon-strated coherence and tunability [23,25]. Alternatively, leakage can be suppressed by engineering qubits with larger anharmonicities such as flux qubits, which have recently also achieved high coherence [26]. WebE. Differential ac-Stark shift or SiZZle A CZ gate with simultaneous ac-Stark shift entangling gate has recently been proposed and demonstrated for both fluxonium [24] and transmon architectures [19,25]asanal-ternative to the CR gate. The constraints for this gate are similar to those for the CR case with the modification that the console aes wood WebMar 3, 2014 · For a transmon qubit, two-photon process has the advantage that it allows the direct transition from the ground state to the second excited state, which is forbidden in the dipole transition by the selection rule. ...

Nonetheless, effectively engineering a high-fidelity two-qutrit entanglement remains a central challenge for realizing qutrit processing in a transmon device. In this work, we apply the differential AC Stark shift to implement a flexible, microwave … WebThe AC Stark effect was discovered in 1955 by American physicists Stanley Autler and Charles Townes . It is the AC equivalent of the static Stark effect which splits the spectral lines of atoms and molecules in a constant electric field. Compared to its DC counterpart, the AC Stark effect is computationally more complex. do fedex trucks have cameras on them WebMar 15, 2024 · In this work, to combat the potential TLS-induced performance fluctuations in a tunable-bus architecture unitizing fixed-frequency transmon qubits, we explore the …
