Lescanne 2020

backend = local.get_backend('EMU:1Q:LESCANNE_2020')

This backend is a numerical model emulating the processor used in the seminal paper by Raphaël Lescanne in 2020, featuring a single cat qubit.

This numerical model is configured to act as a digital twin of the chip used in this paper, using the following parameters:

  • Readout assignment matrix for Mz and Mx: P(1|0)=0.02, P(0|1)=0.06
  • Perfect preparation for Px and Pz
  • Pauli error probabilities interpolated for the “delay/idle” instruction from the T_bf and Gamma_pf plots in the paper

Please note that this design dates back to 2020 and does not represent the current performance of Alice & Bob's cat qubits. Better designs such as the ones documented here have been introduced and will soon be available through Felis.
