Off-resonant interaction of fluctuating photons in a resonator with a qubit increases the qubit dephasing rate. We use this effect to measure a small average number of intracavity photons that are coherently or thermally driven. ...  Read More>>

Superconducting qubits are among the most advanced candidates for achieving fault-tolerant quantum computing. Despite recent significant advancements in the qubit lifetimes, the origin of the loss mechanism for state-of-the-art qubits is still subject to investigation. Furthermore, the successful im ...  Read More>>

We construct the primitive gate set for the digital quantum simulation of the 108-element Σ(36 ×3) group. This is the first time a nonabelian crystal-like subgroup of SU(3) has been constructed for quantum simulation. The gauge link registers and necessary primitives – the inversion gate, the gr ...  Read More>>

Fluxonium qubits are recognized for their high coherence times and high operation fidelities, attributed to their unique design incorporating over 100 Josephson junctions per superconducting loop. However, this complexity poses significant fabrication challenges, particularly in achieving high yield ...  Read More>>
