Sub-MHz SWAP spectroscopy of two-level systems in superconducting qubits
Joaquin Minguzzi, John Clai Owens, Oskar Painter +2
An outstanding challenge in superconducting quantum circuits is mitigating loss from two-level system (TLS) defects. SWAP spectroscopy with flux-tunable qubits can detect individua…
Improving the lifetime of aluminum-based superconducting qubits through atomic layer etching and deposition
Neha Mahuli, Joaquin Minguzzi, Jiansong Gao +9
We present a dry surface treatment combining atomic layer etching and deposition (ALE and ALD) to mitigate dielectric loss in fully fabricated superconducting quantum devices forme…
Hardware-efficient quantum error correction via concatenated bosonic qubits
Harald Putterman, Kyungjoo Noh, Connor T. Hann +118
In order to solve problems of practical importance, quantum computers will likely need to incorporate quantum error correction, where a logical qubit is redundantly encoded in many…
Quantisation and its breakdown in a Hubbard-Thouless pump
Anne-Sophie Walter, Zijie Zhu, Marius Gächter +5
Geometric properties of waves and wave functions can explain the appearance of integer-valued observables throughout physics. For example, these 'topological' invariants describe t…
Topological pumping in a Floquet-Bloch band
Joaquín Minguzzi, Zijie Zhu, Kilian Sandholzer +3
Constructing new topological materials is of vital interest for the development of robust quantum applications. However, engineering such materials often causes technological overh…
Floquet engineering of individual band gaps in an optical lattice using a two-tone drive
Kilian Sandholzer, Anne-Sophie Walter, Joaquín Minguzzi +3
The dynamic engineering of band structures for ultracold atoms in optical lattices represents an innovative approach to understand and explore the fundamental principles of topolog…
