Cavity-assisted dynamic nuclear polarisation
Tristan Lorriaux, Yutian Wen, Patrice Bertet +2
Dynamic nuclear polarisation transfers polarisation from electron to nuclear spins by relying on a dissipative channel. Here we introduce a cavity-based DNP mechanism which uses th…
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…
Absence of Charge Offset Drift in a Transmon Qubit
Adria Rospars, Hector Hutin, Yannick Seis +8
Superconducting quantum circuits are sensitive to their electrostatic environment: uncontrolled charges accumulating on the electrodes of a Josephson junction shift the energy leve…
Addressing spins at the clock transitions with a frequency- and bandwidth-tunable superconducting resonator
Yutian Wen, V. Ranjan, T. Lorriaux +5
Solid-state spin ensembles addressed via superconducting circuits are promising candidates for quantum memory applications, offering multimodal storage capability and second-long c…
Observation and mitigation of microwave echoes from dielectric defects in Josephson traveling wave amplifiers
Matteo Boselli, Joel Grebel, Ambroise Peugeot +3
Amplifying microwave signals with a noise close to the minimum imposed by quantum mechanics is now routinely performed with superconducting quantum devices. In particular, Josephso…
Amplifying microwave pulses with a single qubit engine fueled by quantum measurements
Rémy Dassonneville, Cyril Elouard, Romain Cazali +4
Recent progress in manipulating individual quantum systems enables the exploration of engines exploiting non-classical resources. One of the most appealing is the energy provided b…
Preparing Schrödinger cat states in a microwave cavity using a neural network
Hector Hutin, Pavlo Bilous, Chengzhi Ye +8

Monitoring the energy of a cavity by observing the emission of a repeatedly excited qubit
Hector Hutin, Antoine Essig, Réouven Assouly +3
The number of excitations in a large quantum system (harmonic oscillator or qudit) can be measured in a quantum nondemolition manner using a dispersively coupled qubit. It typicall…
Improving magnetic-field resilience of NbTiN planar resonators using a hard-mask fabrication technique
Arne Bahr, Matteo Boselli, Benjamin Huard +1
High-quality factor microwave resonators operating in a magnetic field are a necessity for some quantum sensing applications and hybrid platforms. Losses in microwave superconducti…
