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…
Cloaking a qubit in a cavity
Cristóbal Lledó, Rémy Dassonneville, Adrien Moulinas +5
Cavity quantum electrodynamics (QED) uses a cavity to engineer the mode structure of the vacuum electromagnetic field such as to enhance the interaction between light and matter. E…
Multipartite Entanglement in Rabi Driven Superconducting Qubits
M. Lu, J. L. Ville, J. Cohen +12
Exploring highly connected networks of qubits is invaluable for implementing various quantum algorithms and simulations as it allows for entangling qubits with reduced circuit dept…
Reminiscence of classical chaos in driven transmons
Joachim Cohen, Alexandru Petrescu, Ross Shillito +1
Transmon qubits are ubiquitously used in superconducting quantum information processor architectures. Strong drives are required to realize fast, high-fidelity, gates and measureme…
Dynamics of Transmon Ionization
Ross Shillito, Alexandru Petrescu, Joachim Cohen +6
Qubit measurement and control in circuit QED rely on microwave drives, with higher drive amplitudes ideally leading to faster processes. However, degradation in qubit coherence tim…
Quantum computation with cat qubits
Jérémie Guillaud, Joachim Cohen, Mazyar Mirrahimi
These are the lecture notes from the 2019 Les Houches Summer School on "Quantum Information Machines". After a brief introduction to quantum error correction and bosonic codes, we…
Degeneracy-preserving quantum non-demolition measurement of parity-type observables for cat-qubits
Joachim Cohen, W. Clarke Smith, Michel H. Devoret +1
A central requirement for any quantum error correction scheme is the ability to perform quantum non-demolition measurements of an error syndrome, corresponding to a special symmetr…
Dissipation-induced continuous quantum error correction for superconducting circuits
Joachim Cohen, Mazyar Mirrahimi
Quantum error correction (QEC) is a crucial step towards long coherence times required for efficient quantum information processing (QIP). One major challenge in this direction con…
Storage of up-converted telecom photons in a doped crystal
Nicolas Maring, Kutlu Kutluer, Joachim Cohen +4
We report on an experiment that demonstrates the frequency up-conversion of telecommunication wavelength single-photon-level pulses to be resonant with a :$\mathr…
