On-Demand Directional Microwave Photon Emission Using Waveguide Quantum Electrodynamics
Bharath Kannan, Aziza Almanakly, Youngkyu Sung +16
Routing quantum information between non-local computational nodes is a foundation for extensible networks of quantum processors. Quantum information transfer between arbitrary node…
Improving qubit coherence using closed-loop feedback
Antti Vepsäläinen, Roni Winik, Amir H. Karamlou +11
Superconducting qubits are a promising platform for building a larger-scale quantum processor capable of solving otherwise intractable problems. In order for the processor to reach…
Probing quantum information propagation with out-of-time-ordered correlators
Jochen Braumüller, Amir H. Karamlou, Yariv Yanay +13
Interacting many-body quantum systems show a rich array of physical phenomena and dynamical properties, but are notoriously difficult to study: they are challenging analytically an…
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…
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…
