Circuit quantization with time-dependent magnetic fields for realistic geometries

Roman-Pascal Riwar, David P. DiVincenzo

Quantum circuit theory has become a powerful and indispensable tool to predict the dynamics of superconducting circuits. Surprisingly however, the question of how to properly accou…

Charge quantization and detector resolution

Roman-Pascal Riwar

Charge quantization, or the absence thereof, is a central theme in quantum circuit theory, with dramatic consequences for the predicted circuit dynamics. Very recently, the questio…

Transport fluctuation relations in interacting quantum pumps

Roman-Pascal Riwar, Janine Splettstoesser

The understanding of out-of-equilibrium fluctuation relations in small open quantum systems has been a focal point of research in recent years. In particular, for systems with adia…

Efficient quasiparticle traps with low dissipation through gap engineering

Roman-Pascal Riwar, Gianluigi Catelani

Quasiparticles represent an intrinsic source of perturbation for superconducting qubits, leading to both dissipation of the qubit energy and dephasing. Recently, it has been shown…

Fractional charges in conventional sequential electron tunneling

Roman-Pascal Riwar

The notion of fractional charges was up until now reserved for quasiparticle excitations emerging in strongly correlated quantum systems, such as Laughlin states in the fractional…

Dissipation by normal-metal traps in transmon qubits

Roman-Pascal Riwar, Leonid I. Glazman, Gianluigi Catelani

Quasiparticles are an intrinsic source of relaxation and decoherence for superconducting qubits. Recent works have shown that normal-metal traps may be used to evacuate quasipartic…
