Fast universal control of a flux qubit via exponentially tunable wave-function overlap
Svend Krøjer, Anders Enevold Dahl, Kasper Sangild Christensen +2
Fast, high fidelity control and readout of protected superconducting qubits are fundamentally challenging due to their inherent insensitivity. We propose a flux qubit variation whi…
Scheme for parity-controlled multi-qubit gates with superconducting qubits
Kasper Sangild Christensen, Nikolaj Thomas Zinner, Morten Kjaergaard
Multi-qubit parity measurements are at the core of many quantum error correction schemes. Extracting multi-qubit parity information typically involves using a sequence of multiple…
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…
Entangling transmons with low-frequency protected superconducting qubits
Andrea Maiani, Morten Kjaergaard, Constantin Schrade
Novel qubits with intrinsic noise protection constitute a promising route for improving the coherence of quantum information in superconducting circuits. However, many protected su…
Gate-Tunable Transmon Using Selective-Area-Grown Superconductor-Semiconductor Hybrid Structures on Silicon
A. Hertel, M. Eichinger, L. O. Andersen +12
We present a gate-voltage tunable transmon qubit (gatemon) based on planar InAs nanowires that are selectively grown on a high resistivity silicon substrate using III-V buffer laye…
Quantum Maxwell's Demon Assisted by Non-Markovian Effects
Kasper Poulsen, Marco Majland, Seth Lloyd +2
Maxwell's demon is the quintessential example of information control, which is necessary for designing quantum devices. In thermodynamics, the demon is an intelligent being who uti…
