Measurement-Reduction Strategies for the 2D-pUCC Ansatz-Based Variational Quantum Eigensolver

During his doctoral work, Louis Jourdan developed the 2D-pUCC (2D-block pair unitary coupled-cluster) ansatz, a novel quantum algorithmic framework that adapts and generalizes the classical Antisymmetric Product of 2D-block Geminals (AP2D-BG) method for quantum computing architectures. The overarching objective of the project is to reduce the measurement cost in variational quantum algorithms for molecular electronic-structure calculations by developing, implementing, and benchmarking measurement-minimization strategies for Hamiltonian expectation-value estimation within the 2D-pUCC variational framework. The host group’s expertise in measurement theory and quantum resource optimization provides the methodological framework needed to address one of the most critical bottlenecks of VQE: measurement overhead. By integrating advanced measurement-reduction techniques into the 2D-pUCC framework, the project strengthens the theoretical developments achieved under the supervision of Patrick Cassam-Chenaï while simultaneously advancing the host group’s research on efficient quantum-algorithm implementation.
