From Wavefunction Regularity to Eigenvector Conditioning: Accuracy--Cost Trade-offs of Quantum Algorithms for Non-Hermitian Transcorrelated Hamiltonians
Cheng-Lin Hong, Emiel Koridon, Paul K. Faehrmann +3
The electron--electron Coulomb singularity forces cusp structure in electronic wavefunctions. This cusp structure limits wavefunction regularity and slows the convergence of expans…

Constant-Depth Quantum Imaginary Time Evolution Using Dynamic Fan-out Circuits
Albert Lund, Erika Magnusson, Werner Dobrautz +1
Dynamic quantum circuits combine mid-circuit measurement with classical feed-forward, enabling circuit constructions with reduced entangling-gate depth. Here, we investigate their…
