Nonreciprocal devices based on voltage-tunable junctions
Catherine Leroux, Adrian Parra-Rodriguez, Ross Shillito +6
We propose to couple the flux degree of freedom of one mode with the charge degree of freedom of a second mode in a hybrid superconducting-semiconducting architecture. Nonreciproci…
Error mitigation via stabilizer measurement emulation
A. Greene, M. Kjaergaard, M. E. Schwartz +16
Dynamical decoupling (DD) is a widely-used quantum control technique that takes advantage of temporal symmetries in order to partially suppress quantum errors without the need reso…
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…
Generating Spatially Entangled Itinerant Photons with Waveguide Quantum Electrodynamics
Bharath Kannan, Daniel Campbell, Francisca Vasconcelos +10
Realizing a fully connected network of quantum processors requires the ability to distribute quantum entanglement. For distant processing nodes, this can be achieved by generating,…
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…
Characterizing and optimizing qubit coherence based on SQUID geometry
Jochen Braumüller, Leon Ding, Antti Vepsäläinen +12
The dominant source of decoherence in contemporary frequency-tunable superconducting qubits is 1/ flux noise. To understand its origin and find ways to minimize its impact, we s…
