Intermodulation Distortion in a Josephson Traveling Wave Parametric Amplifier
Ants Remm, Sebastian Krinner, Nathan Lacroix +5
Josephson traveling wave parametric amplifiers enable the amplification of weak microwave signals close to the quantum limit with large bandwidth, which has a broad range of applic…
Magnetic imaging of superconducting qubit devices with scanning SQUID-on-tip
E. Marchiori, L. Ceccarelli, N. Rossi +6
We use a scanning superconducting quantum interference device (SQUID) to image the magnetic flux produced by a superconducting device designed for quantum computing. The nanometer-…
Realizing Repeated Quantum Error Correction in a Distance-Three Surface Code
Sebastian Krinner, Nathan Lacroix, Ants Remm +13
Quantum computers hold the promise of solving computational problems which are intractable using conventional methods. For fault-tolerant operation quantum computers must correct e…
Realizing Quantum Convolutional Neural Networks on a Superconducting Quantum Processor to Recognize Quantum Phases
Johannes Herrmann, Sergi Masot Llima, Ants Remm +15
Quantum computing crucially relies on the ability to efficiently characterize the quantum states output by quantum hardware. Conventional methods which probe these states through d…
Benchmarking Coherent Errors in Controlled-Phase Gates due to Spectator Qubits
S. Krinner, S. Lazar, A. Remm +7
A major challenge in operating multi-qubit quantum processors is to mitigate multi-qubit coherent errors. For superconducting circuits, besides crosstalk originating from imperfect…
Improving the Performance of Deep Quantum Optimization Algorithms with Continuous Gate Sets
Nathan Lacroix, Christoph Hellings, Christian Kraglund Andersen +9
Variational quantum algorithms are believed to be promising for solving computationally hard problems and are often comprised of repeated layers of quantum gates. An example thereo…
