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…
Optimal absorption and emission of itinerant fields into a spin ensemble memory
Linda Greggio, Tristan Lorriaux, Alexandru Petrescu +2
Quantum memories integrated in a modular quantum processing architecture can rationalize the resources required for quantum computation. This work focuses on spin-based quantum mem…
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…
