Engineering, Control, and Longitudinal Readout of Floquet Qubits
نویسندگان
چکیده
Time-dependent eigenstates of Hamiltonians offer a large degree tunability, which can be leveraged to operate single- and two-qubit gates so that they stay dynamically protected from noise. However, the usual analytical techniques for describing these are limited systems subject drives different frequencies. Thus authors generalize Floquet approach understanding such systems, provide protocols robustly control measure complex systems.

متن کاملHigh fidelity readout of trapped ion qubits
We demonstrate single-shot qubit readout with a fidelity sufficient for fault-tolerant quantum computation. For an optical qubit stored in 40Ca+ we achieve 99.991(1)% average readout fidelity in 10(6) trials, using time-resolved photon counting. An adaptive measurement technique allows 99.99% fidelity to be reached in 145 micros average detection time. For 43Ca+, we propose and implement an opt...

15 صفحه اولCatch-disperse-release readout for superconducting qubits.
We analyze a single-shot readout for superconducting qubits via the controlled catch, dispersion, and release of a microwave field. A tunable coupler is used to decouple the microwave resonator from the transmission line during the dispersive qubit-resonator interaction, thus circumventing damping from the Purcell effect. We show that, if the qubit frequency tuning is sufficiently adiabatic, a ...
متن کاملMeasurement efficiency and n-shot readout of spin qubits.
We consider electron spin qubits in quantum dots and define a measurement efficiency e to characterize reliable measurements via n-shot readouts. We propose various implementations based on a double dot and a quantum point contact (QPC) and show that the associated efficiencies e vary between 50% and 100%, allowing single-shot readout in the latter case. We model the readout microscopically and...
