Removing leakage-induced correlated errors in superconducting quantum error correction
M. McEwen, D. Kafri, Z. Chen +48
Quantum computing can become scalable through error correction, but logical error rates only decrease with system size when physical errors are sufficiently uncorrelated. During co…
Accurately computing electronic properties of a quantum ring
C. Neill, T. McCourt, X. Mi +89
A promising approach to study condensed-matter systems is to simulate them on an engineered quantum platform. However, achieving the accuracy needed to outperform classical methods…
Diabatic gates for frequency-tunable superconducting qubits
R. Barends, C. M. Quintana, A. G. Petukhov +43
We demonstrate diabatic two-qubit gates with Pauli error rates down to in as fast as 18 ns using frequency-tunable superconducting qubits. This is achieved by…
Fluctuations of Energy-Relaxation Times in Superconducting Qubits
P. V. Klimov, J. Kelly, Z. Chen +30
Superconducting qubits are an attractive platform for quantum computing since they have demonstrated high-fidelity quantum gates and extensibility to modest system sizes. Nonethele…
High speed flux sampling for tunable superconducting qubits with an embedded cryogenic transducer
B. Foxen, J. Y. Mutus, E. Lucero +26
We develop a high speed on-chip flux measurement using a capacitively shunted SQUID as an embedded cryogenic transducer and apply this technique to the qualification of a near-term…
Characterization and Reduction of Capacitive Loss Induced by Sub-Micron Josephson Junction Fabrication in Superconducting Qubits
A. Dunsworth, A. Megrant, C. Quintana +20
Josephson junctions form the essential non-linearity for almost all superconducting qubits. The junction is formed when two superconducting electrodes come within 1 nm of eac…
