Integrated tool-set for Control, Calibration and Characterization of quantum devices applied to superconducting qubits
Nicolas Wittler, Federico Roy, Kevin Pack +6
Efforts to scale-up quantum computation have reached a point where the principal limiting factor is not the number of qubits, but the entangling gate infidelity. However, the highl…
Coupling a Superconducting Qubit to a Left-Handed Metamaterial Resonator
S. Indrajeet, H. Wang, M. D. Hutchings +4
Metamaterial resonant structures made from arrays of superconducting lumped circuit elements can exhibit microwave mode spectra with left-handed dispersion, resulting in a high den…
Self gravity decoheres quantum systems
Alessio Lapponi, Stefano Mancini, Frank K. Wilhelm +1
We study the effects of self gravity on the quantum state of a massive and static particle that initially contains quantum coherence between two positions. We employ linearized qua…
Quantum Simulation of a Discrete-Time Quantum Stochastic Walk
Peter K. Schuhmacher, Luke C. G. Govia, Bruno G. Taketani +1
Quantum walks have been shown to have a wide range of applications, from artificial intelligence, to photosynthesis, and quantum transport. Quantum stochastic walks (QSWs) generali…
An introduction into optimal control for quantum technologies
Frank K. Wilhelm, Susanna Kirchhoff, Shai Machnes +2
In this series of lectures, we would like to introduce the audience to quantum optimal control. The first lecture will cover basic ideas and principles of optimal control with the…
Leakage reduction in fast superconducting qubit gates via optimal control
Max Werninghaus, Daniel J. Egger, Federico Roy +3
Reaching high speed, high fidelity qubit operations requires precise control over the shape of the underlying pulses. For weakly anharmonic systems, such as superconducting transmo…
A superconducting detector that counts microwave photons up to two
Andrii M. Sokolov, Frank K. Wilhelm
We propose a detector of microwave photons which can distinguish the vacuum state, one-photon state, and the states with two or more photons. Its operation is based on the two-phot…
Roadmap for quantum simulation of the fractional quantum Hall effect
Michael Kaicher, Simon Balthasar Jäger, Pierre-Luc Dallaire-Demers +1
A major motivation for building a quantum computer is that it provides a tool to efficiently simulate strongly correlated quantum systems. In this work, we present a detailed roadm…
Approximating the quantum approximate optimization algorithm with digital-analog interactions
David Headley, Thorge Müller, Ana Martin +3
The quantum approximate optimisation algorithm was proposed as a heuristic method for solving combinatorial optimisation problems on near-term quantum computers and may be among th…
