Sound and Efficient Certification of High-Quality Qubit Operations: Theory and Experiment
Nikolai Miklin, Jan Nöller, José Martínez +4
Can a high-quality quantum gate be certified when uncharacterized state-preparation and measurement errors are dominant? Can this be achieved with low experimental overhead? Here,…
The most discriminable quantum states in the multicopy regime
Maria Kvashchuk, Polina Chernyshova, Lucas E. A. Porto +3
This work investigates which sets of quantum states give rise to the highest achievable success probability in minimum-error state discrimination if multiple copies of the unknown…
Entanglement-breaking channels are a quantum memory resource
Lucas B. Vieira, Huan-Yu Ku, Costantino Budroni
Entanglement-breaking channels (equivalently, measure-and-prepare channels) are an important class of quantum operations noted for their ability to destroy multipartite spatial qua…
Certifying Quantum Gates via Automata Advantage
Anna Schroeder, Lucas B. Vieira, Jan Nöller +2
There is growing interest in developing rigorous tests of quantumness that are feasible even before practical quantum advantages become a reality. Such tests not only aim to certif…
