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…

Beyond asymptotic scaling: Comparing functional quantum linear solvers
Andreea-Iulia Lefterovici, Michael Perk, Debora Ramacciotti +3
Solving systems of linear equations is a key subroutine in many quantum algorithms. In the last 15 years, many quantum linear solvers (QLS) have been developed, competing to achiev…

Effective dynamics from minimising dissipation
Antonio F. Rotundo, Paolo Perinotti, Alessandro Bisio
It is known that the same physical system can be described by different effective theories depending on the scale at which it is observed. In this work, we formulate a prescription…
