Interconnecting Regional QKD Networks: Hybrid Key Delivery Across Quantum Domains
David Barral, Aitor Brazaola-Vicario, Diego Cifrián +9
QKD technology is being increasingly adopted inside the network core for protecting information transport against any form of computational attacks. However, the use of QKD for wid…
Quantum Field Theory Universality Criterion for Layered Programmable Decompositions
Javier Álvarez-Vizoso, David Barral
The decomposition of arbitrary unitary transformations into sequences of simpler, physically realizable operations is a foundational problem in quantum information science, quantum…
Continuous-variable spatio-spectral quantum networks in nonlinear photonic lattices
Natalia Costas, Nadia Belabas, David Barral
Multiplexing information in different degrees of freedom and use of integrated and fiber-optic components are natural solutions to the scalability bottleneck in optical quantum com…
Review of Distributed Quantum Computing. From single QPU to High Performance Quantum Computing
David Barral, F. Javier Cardama, Guillermo Díaz +10
The emerging field of quantum computing has shown it might change how we process information by using the unique principles of quantum mechanics. As researchers continue to push th…
