Superconducting circuits host two-level systems with lifetimes exceeding one second
Mathieu Féchant, Phillip Lenhard, Nicolas Gosling +5
Understanding the microscopic environment of superconducting qubits is a central challenge for quantum technologies. Parasitic two-level systems (TLSs) of various microscopic origi…
Parametric two-qubit gates via Landau-Zener interference
Simon Geisert, Albert Hertel, Soeren Ihssen +23
We propose and demonstrate gates between two superconducting qubits based on quantum interference of consecutive Landau-Zener (LZ) transitions. This gate mechanism bridges between…
Probing the memory of a superconducting qubit environment
Nicolas Gosling, Denis Bénâtre, Nicolas Zapata +8
Achieving fault tolerance with superconducting quantum processors requires qubits to operate within the regime of threshold theorems based on the Born-Markov approximation. This ap…
