Magic in quantum trajectory unravelings of noisy random quantum circuits
Sara Santos, Alessio Paviglianiti, Vincenzo Savona
The quantum-trajectory description of a noisy quantum circuit is not unique: every Kraus representation of the noise channel defines a different unraveling, i.e., a different ensem…
Efficient re-sampling in quasi-probability decompositions
Sara Santos, Stefan Woerner, Vincenzo Savona +1
Near-term quantum devices are limited by noise and hardware constraints, motivating algorithmic approaches that trade circuit complexity for increased sampling overhead. Quasi-prob…
Analytic gradients for low-rank quantum optimal control
Leo Goutte, Vincenzo Savona
We introduce low-rank optimal control (LROC), a method for designing control pulses in open quantum systems whose full density-matrix simulation is prohibitively expensive. The met…
The true cost of factoring: Linking magic and number-theoretic complexity in Shor's algorithm
Alessio Paviglianiti, Matteo Seclì, Emanuele Tirrito +1
The execution cost of quantum algorithms is typically quantified through asymptotic gate counts and qubit register sizes, yet these metrics do not directly capture which genuinely…
