Engineering multi-photon dissipation with a dc-voltage-biased Josephson junction
Marco Paradina, Ambroise Peugeot, Roberto Negrin +8
Multi-photon dissipation -- a key resource for bosonic qubits -- is usually realized by parametrically pumping a Josephson coupler at the cost of spurious nonlinear terms. Here we…
Enhancing dissipative cat qubit protection by squeezing
Rémi Rousseau, Diego Ruiz, Emanuele Albertinale +38
Dissipative cat-qubits are a promising architecture for quantum processors due to their built-in quantum error correction. By leveraging two-photon stabilization, they achieve an e…
A cat qubit stabilization scheme using a voltage biased Josephson junction
Thiziri Aissaoui, Anil Murani, Raphaël Lescanne +1
DC-voltage-biased Josephson junctions have been recently employed in superconducting circuits for Hamiltonian engineering, demonstrating microwave amplification, single photon sour…
Autoparametric resonance extending the bit-flip time of a cat qubit up to 0.3 s
Antoine Marquet, Antoine Essig, Joachim Cohen +9
Cat qubits, for which logical and are coherent states of a harmonic mode, offer a promising route towards quantum error correction. Using dis…
One hundred second bit-flip time in a two-photon dissipative oscillator
C. Berdou, A. Murani, U. Reglade +19
Current implementations of quantum bits (qubits) continue to undergo too many errors to be scaled into useful quantum machines. An emerging strategy is to encode quantum informatio…
