Enhancing dissipative cat qubit protection by squeezing
Rémi Rousseau, Diego Ruiz, Emanuele Albertinale +38
Dissipative cat-qubits are a promising architecture for quantum processors due to their built-in quantum error correction. By leveraging two-photon stabilization, they achieve an e…
Multiplexed Readout of Superconducting Qubits Using a 3D Re-entrant Cavity Filter
Mustafa Bakr, Simone D. Fasciati, Shuxiang Cao +7
Hardware efficient methods for high fidelity quantum state measurements are crucial for superconducting qubit experiments, as qubit numbers grow and feedback and state reset begin…
Complementing the transmon by integrating a geometric shunt inductor
Simone D. Fasciati, Boris Shteynas, Giulio Campanaro +5
We realize a single-Josephson-junction transmon qubit shunted by a simple geometric inductor. We couple it capacitively to a conventional transmon and show that the ZZ interaction…
Encoding optimization for quantum machine learning demonstrated on a superconducting transmon qutrit
Shuxiang Cao, Weixi Zhang, Jules Tilly +9
Qutrits, three-level quantum systems, have the advantage of potentially requiring fewer components than the typically used two-level qubits to construct equivalent quantum circuits…
Emulating two qubits with a four-level transmon qudit for variational quantum algorithms
Shuxiang Cao, Mustafa Bakr, Giulio Campanaro +7
Using quantum systems with more than two levels, or qudits, can scale the computation space of quantum processors more efficiently than using qubits, which may offer an easier phys…
Efficient characterization of qudit logical gates with gate set tomography using an error-free Virtual-Z-gate model
Shuxiang Cao, Deep Lall, Mustafa Bakr +7
Gate-set tomography (GST) characterizes the process matrix of quantum logic gates, along with measurement and state preparation errors in quantum processors. GST typically requires…
Characterisation of spatial charge sensitivity in a multi-mode superconducting qubit
J. Wills, G. Campanaro, S. Cao +3
Understanding and suppressing sources of decoherence is a leading challenge in building practical quantum computers. In superconducting qubits, low frequency charge noise is a well…
High Coherence in a Tileable 3D Integrated Superconducting Circuit Architecture
Peter A. Spring, Shuxiang Cao, Takahiro Tsunoda +11
We report high qubit coherence as well as low crosstalk and single-qubit gate errors in a superconducting circuit architecture that promises to be tileable to 2D lattices of qubits…
