Efficient Computation of QKD Key Rates without Semidefinite Programming
Bence Temesi, Antoine Gansel, Gereon Koßmann +1
Translating observed data into a reliable estimate of the secure key rate is a crucial step for operating a quantum key distribution device. We provide a computational method for t…

Approximate Sparse State Preparation with the Grover-Rudolph Algorithm
Debora Ramacciotti, Martin Steinbach, Bence Temesi +2
Sparse quantum state preparation is a common subroutine in quantum algorithms, where classical data with few nonzero entries must be loaded into a quantum state. In this work, we c…
