Inertial Counterdiabatic Driving
Julián Ferreiro-Vélez, F. A. Cárdenas-López, F. Motzoi +1
We introduce an inertial counterdiabatic (CD) protocol that reformulates shortcut-to-adiabaticity design as a moving-frame diagonalization problem. The method employs the Magnus ex…
Simple analytical flux-tuned iSWAP pulses for leakage suppression
Dimitrios Georgiadis, Boxi Li, Asier Galicia +3
Fast, high-fidelity two-qubit gates are a key requirement for fault-tolerant quantum computation. Tunable coupler architectures provide a flexible approach for implementing entangl…
Quantum circuit partition as a maze: emerging percolation transition via path finding
P. Zentilini, M. Guatto, F. Preti +4
In quantum circuit optimization, circuit partitioning enables the optimization process to be parallelized across multiple devices. Each device is responsible for either reducing th…
Kraus map closed-form solution for general master equation dynamics
Shahrukh Chishti, Francisco Andrés Cárdenas-López, Felix Motzoi
The Kraus representation of quantum channels allows for a precise emulation of the complex dynamics that take place on quantum processors, whether for benchmarking algorithms, pred…
Analytical blueprint for 99.999% fidelity X-gates on present superconducting hardware under strong driving
José Diogo Da Costa Jesus, Boxi Li, Yuan Gao +3
Achieving very fast gates that undercut the natural limits set by decoherence requires going into the strong driving limit. Realizing single-qubit control predicted beyond semi-cla…
Ultrafast Single Qubit Gates through Multi-Photon Transition Removal
Y. Gao, A. Galicia, J. D. Da Costa Jesus +12
One of the main enablers in quantum computing is having qubit control that is precise and fast. However, qubits typically have multilevel structures making them prone to unwanted t…

Computation of observables and their gradients on near-term quantum hardware is a central aspect of any quantum algorithm. In this work, we first review standard approaches to the…
Real-time adaptive quantum error correction by model-free multi-agent learning
Manuel Guatto, Francesco Preti, Michael Schilling +3
Quantum error correction (QEC) is essential for scalable quantum computing, yet existing approaches rely on static assumptions about noise that break down in realistic hardware, wh…
