Microwave Package Design for Superconducting Quantum Processors
Sihao Huang, Benjamin Lienhard, Greg Calusine +10
Solid-state qubits with transition frequencies in the microwave regime, such as superconducting qubits, are at the forefront of quantum information processing. However, high-fideli…
Realization of high-fidelity CZ and ZZ-free iSWAP gates with a tunable coupler
Youngkyu Sung, Leon Ding, Jochen Braumüller +14
High-fidelity two-qubit gates at scale are a key requirement to realize the full promise of quantum computation and simulation. The advent and use of coupler elements to tunably co…
Comparison of Dielectric Loss in Titanium Nitride and Aluminum Superconducting Resonators
Alexander Melville, Greg Calusine, Wayne Woods +8
Lossy dielectrics are a significant source of decoherence in superconducting quantum circuits. In this report, we model and compare the dielectric loss in bulk and interfacial diel…
Engineering Framework for Optimizing Superconducting Qubit Designs
Fei Yan, Youngkyu Sung, Philip Krantz +6
Superconducting quantum technologies require qubit systems whose properties meet several often conflicting requirements, such as long coherence times and high anharmonicity. Here,…
Universal non-adiabatic control of small-gap superconducting qubits
Daniel L. Campbell, Yun-Pil Shim, Bharath Kannan +7
Resonant transverse driving of a two-level system as viewed in the rotating frame couples two degenerate states at the Rabi frequency, an amazing equivalence that emerges in quantu…
Multi-level Quantum Noise Spectroscopy
Youngkyu Sung, Antti Vepsäläinen, Jochen Braumüller +14
System noise identification is crucial to the engineering of robust quantum systems. Although existing quantum noise spectroscopy (QNS) protocols measure an aggregate amount of noi…
