Hamiltonian Simulation and Linear Combination of Unitary Decomposition of Structured Matrices
Robin Ollive, Stéphane Louise
To treat a problem with a Quantum Processing Unit (QPU), it must be transformed into a sequence of quantum operations, or gates: this is the quantum description of the problem. The…
Numerical Error Extraction by Quantum Measurement Algorithm
Clement Ronfaut, Robin Ollive, Stephane Louise
Important quantum algorithm routines allow the implementation of specific quantum operations (a.k.a. gates) by combining basic quantum circuits with an iterative structure. In this…
Quantum Arithmetic-based on Quantum Signal Processing
Robin Ollive, Stephane Louise
As in classical reversible computing, Quantum Arithmetic is typically seen as a set of tools that process binary data encoded into a quantum register to set the value of another qu…
Gate Efficient Composition of Hamiltonian Simulation and Block-Encoding with its Application on HUBO, Chemistry and Finite Difference Method
Robin Ollive, Stephane Louise
This article proposes a formalism which unifies Hamiltonian simulation techniques from different fields. This formalism leads to a competitive method to construct the Hamiltonian s…
