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…
Deep Neural Network Discrimination of Multiplexed Superconducting Qubit States
Benjamin Lienhard, Antti Vepsäläinen, Luke C. G. Govia +15
Demonstrating a quantum computational advantage will require high-fidelity control and readout of multi-qubit systems. As system size increases, multiplexed qubit readout becomes a…
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…
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…
