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…
