Quantum error correction with global control
Roberto Menta, Lindsay Bassman Oftelie, Ashkan Abedi +5
Reaching fault tolerance means scaling qubit counts by orders of magnitude, a jump that conventional superconducting architectures cannot sustain without solving the so-called `wir…
Mitigating quantum decoherence via global optimal control
Ashkan Abedi, Roberto Menta, Julien Despres +3
The paper demonstrates that shaping a global drive in superconducting quantum processors can significantly reduce decoherence effects, improving the fidelity of one- and two-qubit…
Global control via quantum actuators
Roberto Menta, Francesco Cioni, Riccardo Aiudi +2
We introduce the concept of quantum actuators as mediators for globally controlled quantum computation. Auxiliary quantum systems act as controllable elements that transiently stor…
Conveyor-belt superconducting quantum computer
Francesco Cioni, Roberto Menta, Riccardo Aiudi +2
The processing unit of a solid-state quantum computer consists in an array of coupled qubits, each locally driven with on-chip microwave lines that route carefully-engineered contr…
Overcoming disorder in superconducting globally driven quantum computing
Riccardo Aiudi, Julien Despres, Roberto Menta +5
We study the impact of static disorder on a globally-controlled superconducting quantum computing architecture based on a quasi-two-dimensional ladder geometry [R. Menta et al., Ph…
Experimental observation of dynamical blockade between transmon qubits via ZZ interaction engineering
Marco Riccardi, Aviv Glezer Moshe, Guido Menichetti +13
We report the experimental realization of strong longitudinal (ZZ) coupling between two superconducting transmon qubits achieved solely through capacitive engineering. By systemati…
