Beyond Unitary Quantum Simulation: Open-System Approaches to Quantum Chemistry toward Quantum Advantage
Michael Marthaler, Elias Zapusek, Florentin Reiter
Quantum simulation is widely regarded as one of the most promising routes to genuine quantum advantage, yet most existing approaches to quantum chemistry are formulated in terms of…
Characterization of coherent errors in gate layers with robustness to Pauli noise
Noah Kaufmann, Ivan Rojkov, Florentin Reiter
Characterization of quantum devices generates insights into their sources of disturbances. State-of-the-art characterization protocols often focus on incoherent noise and eliminate…
Quantum anomaly detection in the latent space of proton collision events at the LHC
Vasilis Belis, Kinga Anna Woźniak, Ema Puljak +7
The ongoing quest to discover new phenomena at the LHC necessitates the continuous development of algorithms and technologies. Established approaches like machine learning, along w…
Two-qubit operations for finite-energy Gottesman-Kitaev-Preskill encodings
Ivan Rojkov, Paul Moser Röggla, Martin Wagener +4
We present techniques for performing two-qubit gates on Gottesman-Kitaev-Preskill (GKP) codes with finite energy, and find that operations designed for ideal infinite-energy codes…
