Two new papers on the arXiv

This spring, two new articles involving members of the groupe appear on the arXiv. Below is a brief summary along with the link to access them.

First article : Transmon qubits are a leading candidate to encode quantum information. However, it is known that the strong voltages used to measure these qubits can induce measurement errors by exciting the qubit to a more energetic state. In collaboration with the University of Rochester, we studied these excitations and were able to control them. Our theory explains observations and provides tools to improve measurement in the near future.

Second article : One of the advantages of transmon qubits is their resilience against unavoidable electric noise in their environment. However, it was recently suggested that the measurement of these qubits is not protected against such noise. In collaboration with the Karlsruhe Institute of Technology, we studied the effect of electric noise on transmon measurement. Our theory explains observations and suggests strategies to improve measurement in the near future.
