State preservation by repetitive error detection in a superconducting quantum circuit
J. Kelly, R. Barends, A. G. Fowler +19
Quantum computing becomes viable when a quantum state can be preserved from environmentally-induced error. If quantum bits (qubits) are sufficiently reliable, errors are sparse and…
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…
Optimal quantum control using randomized benchmarking
J. Kelly, R. Barends, B. Campbell +19
We present a method for optimizing quantum control in experimental systems, using a subset of randomized benchmarking measurements to rapidly infer error. This is demonstrated to i…
Qubit architecture with high coherence and fast tunable coupling
Yu Chen, C. Neill, P. Roushan +20
We introduce a superconducting qubit architecture that combines high-coherence qubits and tunable qubit-qubit coupling. With the ability to set the coupling to zero, we demonstrate…
Logic gates at the surface code threshold: Superconducting qubits poised for fault-tolerant quantum computing
R. Barends, J. Kelly, A. Megrant +19
A quantum computer can solve hard problems - such as prime factoring, database searching, and quantum simulation - at the cost of needing to protect fragile quantum states from err…
Fast Scalable State Measurement with Superconducting Qubits
Daniel Sank, Evan Jeffrey, J. Y. Mutus +15
Progress in superconducting qubit experiments with greater numbers of qubits or advanced techniques such as feedback requires faster and more accurate state measurement. We have de…
