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…
Cavity-mediated probabilistic magic -gate injection
Sofia Cocciaretto, Roberto Menta, Vittorio Giovannetti
Non-Clifford gates are a necessary resource for universal quantum computation, yet their fault-tolerant implementation typically relies on magic-state distillation, which incurs si…
Generalized multilevel amplitude damping channels and their thermodynamic performances
Vito Vetrano, Vittorio Giovannetti, Vasco Cavina
We introduce a new class of quantum channels, the Generalized Multilevel Amplitude Damping (GMAD) channels, to model noise and decoherence effects in a qudit coupled to a thermal e…
Exact requirements for battery-assisted qubit gates
Riccardo Castellano, Vasco Cavina, Martà Perarnau-Llobet +2
We consider the implementation of a unitary gate on a qubit system S via a global energy-preserving operation acting on S and an auxiliary system B that can be seen as a battery. W…
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…
