An extensive theory of nonlinearly intercoupled pseudomodes for noise model reduction in circuit QED
M. Gabriela Boada G., Nicolas Dirnegger, Andrea Delgado +1
Superconducting circuit quantum electrodynamical (cQED) platforms present a persistent modeling challenge: the intrinsic nonlinearity of the Josephson potential couples to a dissip…
Nonreciprocal quantum information processing with superconducting diodes in circuit quantum electrodynamics
Nicolas Dirnegger, Prineha Narang, Arpit Arora
Introducing new components and functionalities into quantum devices is critical in advancing state-of-the-art hardware. Here, we propose superconducting diodes (SDs) as a coherent…
Probing Time Reversal Symmetry Breaking using a Nonlinear Superconducting Ring Resonator
Nicolas Dirnegger, Marie Wesson, Arpit Arora +5
Time-reversal symmetry breaking (TRSB) has been central to detecting exotic phases of matter. Here, we leverage the circuit electrodynamics capabilities of superconducting devices…
Distilled remote entanglement between superconducting qubits across optical channels
Nicolas Dirnegger, Moein Malekakhlagh, Vikesh Siddhu +5
A promising quantum computing architecture comprises modules of superconducting quantum processors linked via optical channels using quantum transducers. As quantum transducer hard…
Efficient Multiparty Entanglement Distribution in Dynamic Quantum Networks
Roberto Negrin, Nicolas Dirnegger, William Munizzi +2
Distributing multipartite entanglement over a quantum network means routing it through a shared resource state. Existing measurement-based schemes search for a fresh path and re-ve…
