Implementation of Conditional-Phase Gates based on tunable ZZ-Interactions
Michele C. Collodo, Johannes Herrmann, Nathan Lacroix +7
High fidelity two-qubit gates exhibiting low crosstalk are essential building blocks for gate-based quantum information processing. In superconducting circuits two-qubit gates are…
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…
Repeated Quantum Error Detection in a Surface Code
Christian Kraglund Andersen, Ants Remm, Stefania Lazar +6
The realization of quantum error correction is an essential ingredient for reaching the full potential of fault-tolerant universal quantum computation. Using a range of different s…
Hybrid Quantum Error Correction in Qubit Architectures
Lasse Bjørn Kristensen, Morten Kjaergaard, Christian Kraglund Andersen +1
Noise and errors are inevitable parts of any practical implementation of a quantum computer. As a result, large-scale quantum computation will require ways to detect and correct er…
Quantum versus classical switching dynamics of driven-dissipative Kerr resonators
Christian Kraglund Andersen, Archana Kamal, Nicholas A. Masluk +3
We report a first-principles study of the driven dissipative dynamics for Kerr oscillators in the mesoscopic regime. This regime is characterized by large Kerr nonlinearity, realiz…
