Characterization and reduction of microfabrication-induced decoherence in superconducting quantum circuits
C. M. Quintana, A. Megrant, Z. Chen +18
Many superconducting qubits are highly sensitive to dielectric loss, making the fabrication of coherent quantum circuits challenging. To elucidate this issue, we characterize the i…
Observation of topological transitions in interacting quantum circuits
P. Roushan, C. Neill, Yu Chen +21
The discovery of topological phases in condensed matter systems has changed the modern conception of phases of matter. The global nature of topological ordering makes these phases…
Rolling quantum dice with a superconducting qubit
R. Barends, J. Kelly, A. Veitia +20
One of the key challenges in quantum information is coherently manipulating the quantum state. However, it is an outstanding question whether control can be realized with low error…
Simulating weak localization using superconducting quantum circuits
Yu Chen, P. Roushan, D. Sank +15
Understanding complex quantum matter presents a central challenge in condensed matter physics. The difficulty lies in the exponential scaling of the Hilbert space with the system s…
