Dispersive thermometry with a Josephson junction coupled to a resonator
O. -P. Saira, M. Zgirski, K. L. Viisanen +2
We have embedded a small Josephson junction in a microwave resonator that allows simultaneous dc biasing and dispersive readout. Thermal fluctuations drive the junction into phase…
Mitigating information leakage in a crowded spectrum of weakly anharmonic qubits
V. Vesterinen, O. -P. Saira, A. Bruno +1
A challenge for scaling up quantum processors using frequency-crowded, weakly anharmonic qubits is to drive individual qubits without causing leakage into non-computational levels…
Distribution of Entropy Production in a Single-Electron Box
J. V. Koski, T. Sagawa, O. -P. Saira +6
Recently, the fundamental laws of thermodynamics have been reconsidered for small systems. The discovery of the fluctuation relations has spurred theoretical and experimental studi…
Vanishing quasiparticle density in a hybrid Al/Cu/Al single-electron transistor
O. -P. Saira, A. Kemppinen, V. F. Maisi +1
The achievable fidelity of many nanoelectronic devices based on superconducting aluminum is limited by either the density of residual nonequilibrium quasiparticles n_qp or the dens…
