The Gain-Engineered Transmon
Ian Yang, Francesco Adinolfi, Alessandro Bruno +3
The interaction between a qubit and its environment can be engineered such that one error channel dominates over all others, resulting in noise bias. This property enables error co…
Quantum theory of a three-photon Kerr parametric oscillator
Alessandro Bruno, Patrick P. Potts, Alexander Grimm +1
We investigate the quantum properties of a nonlinear Kerr oscillator driven by a three-photon pump. We derive both exact and approximate analytical expressions for the ground state…
Phase dynamics and dissipation in tunnel ferromagnetic Josephson junctions
F. Calloni, R. Satariano, R. Ferraiuolo +17
We investigate tunnel ferromagnetic Josephson junctions based on Superconductor-Insulator-thin superconductor-Ferromagnet-Superconductor multilayers. A comparative study of their e…
Submicrometer tunnel ferromagnetic Josephson junctions with transmon energy scale
R. Satariano, R. Ferraiuolo, F. Calloni +5
We have realized submicron tunnel ferromagnetic Al/AlO/Al/NiFe/Al Josephson junctions (JJs) in Manhattan-style configuration for qubit applications. These junctio…
Enhancing Kerr-Cat Qubit Coherence with Controlled Dissipation
Francesco Adinolfi, Daniel Z. Haxell, Alessandro Bruno +4
Quantum computing crucially relies on maintaining quantum coherence for the duration of a calculation. Bosonic quantum error correction protects this coherence by encoding qubits i…
Implementation and readout of maximally entangled two-qubit gates quantum circuits in a superconducting quantum processor
Viviana Stasino, Pasquale Mastrovito, Carlo Cosenza +8
Besides noticeable challenges in implementing low-error single- and two-qubit quantum gates in superconducting quantum processors, the readout technique and analysis are a key fact…
Misfit layer superconductors, tuneable bulk heterostructures with strong 2D effects
Tomas Samuely, Martin Gmitra, Tristan Cren +2
Atomically thin layered materials are systems with zero limit bulk-to-surface ratio. Their physical properties are determined by two-dimensionality and strongly affected by interfa…
Towards novel tunability schemes for hybrid ferromagnetic transmon qubits
Halima Giovanna Ahmad, Raffaella Ferraiuolo, Giuseppe Serpico +12
Flux tuning of qubit frequencies in superconducting quantum processors is fundamental for implementing single and multi-qubit gates in quantum algorithms. Typical architectures inv…
Mitigating Errors on Superconducting Quantum Processors through Fuzzy Clustering
Halima G. Ahmad, Roberto Schiattarella, Pasquale Mastrovito +10
Quantum utility has been severely limited in superconducting quantum hardware until now by the modest number of qubits and the relatively high level of control and readout errors,…
