Mitigating Coherent Errors through a Decoherence-Resistant Variational Framework employing Stabilizer State
Giovanni Di Bartolomeo, Giulio Crognaletti, Angelo Bassi +1
Stabilizer states are a central resource in quantum information processing, underpinning a wide range of applications. While they can be efficiently generated via Clifford circuits…
Equivariant Variational Quantum Eigensolver to detect Phase Transitions through Energy Level Crossings
Giulio Crognaletti, Giovanni Di Bartolomeo, Michele Vischi +1
Level spectroscopy stands as a powerful method for identifying the transition point that delineates distinct quantum phases. Since each quantum phase exhibits a characteristic sequ…
Simulating photonic devices with noisy optical elements
Michele Vischi, Giovanni Di Bartolomeo, Massimiliano Proietti +4
Quantum computers are inherently affected by noise. While in the long-term error correction codes will account for noise at the cost of increasing physical qubits, in the near-term…
Efficient quantum algorithm to simulate open systems through a single environmental qubit
Giovanni Di Bartolomeo, Michele Vischi, Tommaso Feri +2
We present an efficient algorithm for simulating open quantum systems dynamics described by the Lindblad master equation on quantum computers, addressing key challenges in the fiel…
Fundamental limits of superconducting quantum computers
Michele Vischi, Luca Ferialdi, Andrea Trombettoni +1
The Continuous Spontaneous Localization (CSL) model is an alternative formulation of quantum mechanics which introduces a noise coupled non linearly to the wave function to account…
