Coherent control of a triangular exchange-only spin qubit
Edwin Acuna, Joseph D. Broz, Kaushal Shyamsundar +14
We demonstrate coherent control of a three-electron exchange-only spin qubit with the quantum dots arranged in a close-packed triangular geometry. The device is tuned to confine on…
Preparation and Measurement of Three-Qubit Entanglement in a Superconducting Circuit
L. DiCarlo, M. D. Reed, L. Sun +7
Traditionally, quantum entanglement has played a central role in foundational discussions of quantum mechanics. The measurement of correlations between entangled particles can exhi…
High-Fidelity Readout in Circuit Quantum Electrodynamics Using the Jaynes-Cummings Nonlinearity
M. D. Reed, L. DiCarlo, B. R. Johnson +4
We demonstrate a qubit readout scheme that exploits the Jaynes-Cummings nonlinearity of a superconducting cavity coupled to transmon qubits. We find that in the strongly-driven dis…
Quantum Non-demolition Detection of Single Microwave Photons in a Circuit
B. R. Johnson, M. D. Reed, A. A. Houck +8
Thorough control of quantum measurement is key to the development of quantum information technologies. Many measurements are destructive, removing more information from the system…
Fast Reset and Suppressing Spontaneous Emission of a Superconducting Qubit
M. D. Reed, B. R. Johnson, A. A. Houck +5
Spontaneous emission through a coupled cavity can be a significant decay channel for qubits in circuit quantum electrodynamics. We present a circuit design that effectively elimina…
