Hiroshi Ueda delivered an invited talk at the 14th Workshop on Quantum Many-Body Computation held in Beijing, China, from April 10 to 12, 2026.

Title of the talk:

“Variational Quantum Partial SVD with Orthogonality Correction: High-Precision Entanglement Spectra from Shallow Circuits”

The presentation introduced recent developments in hybrid quantum-classical algorithms for entanglement spectrum estimation, variational quantum singular value decomposition, and tensor-network-inspired quantum computation.

The workshop also provided opportunities for discussions on quantum algorithms, tensor networks, and future international collaborations.
