Researchers from the Basque Quantum Ecosystem Advance Quantum Algorithms with Approximated Cloning
March 12, 2025A team of researchers linked to the Basque quantum ecosystem demonstrates how quantum cloning techniques can boost the efficiency of quantum algorithms, offering a novel approach to data encoding
A team of researchers linked to the Basque quantum ecosystem (BasQ) has published a study in Physical Review Research titled “Quantum Approximated Cloning-Assisted Density Matrix Exponentiation, that explores how imperfect quantum copies—created via quantum cloning—can enhance the performance of the well-known LMR protocol, used to encode classical data into quantum states. This approach offers a practical workaround to the limitations posed by the no-cloning theorem and could pave the way for more efficient quantum algorithms.
The work was carried out by Pablo Rodriguez-Grasa, Ruben Ibarrondo, Javier Gonzalez-Conde, Yue Ban, Patrick Rebentrost, and Mikel Sanz—researchers from institutions including the University of the Basque Country (UPV/EHU), EHU Quantum Center, TECNALIA, BCAM, and Ikerbasque.
