Fast Microwave-free State Preparation and Measurement of Superconducting Qubits
R. Abraham, F. Amet, P. Anderson +212
Fast, high-fidelity, scalable state preparation and measurement is critical to the realization of a quantum computing system. The state-of-the-art methods for preparation and reado…
Fast, Lifetime-Preserving Readout for High-Coherence Quantum Annealers
Jeffrey A. Grover, James I. Basham, Alexander Marakov +15
We demonstrate, for the first time, that a quantum flux parametron (QFP) is capable of acting as both isolator and amplifier in the readout circuit of a capacitively shunted flux q…
The Resonant Exchange Qubit
J. Medford, J. Beil, J. M. Taylor +4
We introduce a solid-state qubit in which exchange interactions among confined electrons provide both the static longitudinal field and the oscillatory transverse field, allowing r…
Electrically-protected resonant exchange qubits in triple quantum dots
J. M. Taylor, V. Srinivasa, J. Medford
We present a modulated microwave approach for quantum computing with qubits comprising three spins in a triple quantum dot. This approach includes single- and two-qubit gates that…
Self-Consistent Measurement and State Tomography of an Exchange-Only Spin Qubit
J. Medford, J. Beil, J. M. Taylor +7
We report initialization, complete electrical control, and single-shot readout of an exchange-only spin qubit. Full control via the exchange interaction is fast, yielding a demonst…
Relaxation and Readout Visibility of a Singlet-Triplet Qubit in an Overhauser Field Gradient
C. Barthel, J. Medford, H. Bluhm +4
Using single-shot charge detection in a GaAs double quantum dot, we investigate spin relaxation time T_1 and readout visibility of a two-electron singlet-triplet qubit following si…
