Projector Quantum Variational Ansatz
Thomas Dumontier, Robin Ollive, Stephane Louise
Quantum computing offers several algorithms for computing the ground state of a problem Hamiltonian. Algorithms in the Fault-Tolerant Quantum Computing (FTQC) regime, such as Quant…
Hamiltonian Simulation and Linear Combination of Unitary Decomposition of Structured Matrices
Robin Ollive, Stéphane Louise
To process a problem with a Quantum Processing Unit (QPU), it must be transformed into a sequence of quantum operators, or gates. These operators are either packed into a query (i.…
Numerical Error Extraction by Quantum Measurement Algorithm
Clement Ronfaut, Robin Ollive, Stephane Louise
In quantum computing, some of the main quantum operations (i.e., gates) cannot be simply implemented and require an approximation. Major quantum algorithm routines enable the imple…
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…
