Nanoscale stray fields from micromagnets for optimal spin qubit architecture
Sandrine Lopes, Quentin Schaeverbeke, Matthieu M. Desjardins +3
On-chip micromagnets generate local magnetic-field asymmetries, enabling electrical control of spin qubits via electric dipole spin resonance and their integration into circuit qua…
Qubit-Boson Hybrid Beam-Splitter Gate with Kerr Nonlinearity in Circuit QED for Many-Body Dynamics
Andrea Mammola, Giuseppe Di Molfetta, Quentin Schaeverbeke
We introduce a hybrid qubit-boson beam-splitter gate in which a microwave cavity mode couples to an exchange-dressed two-level subsystem of an interacting two-qubit system in the p…
Simulation of quantum annealing on a semiconducting cQED device for Multiple Hypothesis Tracking (MHT) benchmark
Quentin Schaeverbeke, Viktor RadoviÄ, Jean-Marc Divanon +1
We explore the expected performance of a semiconducting spin cQED quantum processor for Multiple Hypothesis Tracking (MHT) algorithm via a quantum annealing procedure. From two dif…
Noisy simulations of Quantum Walk and Quantum Walk search via Quantum Cellular Automata on a semiconducting spin processor emulator
Andrea Mammola, Quentin Schaeverbeke, Giuseppe Di Molfetta
In this work we map NISQ-friendly implementations of the non-interacting QCA to a circuit Quantum Electrodynamics (cQED) hardware. We perform both noiseless and noisy simulations o…
Microsecond-lived quantum states in a carbon-based circuit driven by cavity photons
B. Neukelmance, B. Hue, Q. Schaeverbeke +16
Semiconductor quantum dots are an attractive platform for the realisation of quantum processors. To achieve long-range coupling between them, quantum dots have been integrated into…
Optimal Connectivity from Idle Qubit residual coupling Cross-Talks in a Cavity Mediated Entangling Gate
Andrea Mammola, Quentin Schaeverbeke, Matthieu M. Desjardins
Quantum processors operated through long range interaction mediated by a microwave resonator have been envisioned to allow for high connectivity. The ability to selectively operate…
