Resource-efficient linear-optical generation of GHZ-like states
Suren A. Fldzhyan, Stanislav S. Straupe, Mikhail Yu. Saygin
The paper presents a linear‑optical scheme for generating GHZ‑like multi‑photon entangled states that uses tunable, non‑maximally entangled intermediate states to reduce the photon…
Perturbative photonic matrix-vector multiplication with reduced phase-shift range
S. A. Fldzhyan, S. S. Straupe, M. Yu. Saygin
Programmable photonic meshes provide a promising platform for analog matrix-vector multiplication, but their scalability is often limited by the large phase-shift ranges required i…
Native QR Factorization on Programmable Photonic Meshes
S. A. Fldzhyan, S. S. Straupe, M. Yu. Saygin
We propose a photonic native procedure for computing the QR factorization of a matrix using a programmable unitary interferometer mesh. The method configures the mesh through a seq…
Universal low-depth two-unitary design of programmable photonic circuits
S. A. Fldzhyan, M. Yu. Saygin, S. S. Straupe
The development of large-scale, programmable photonic circuits capable of performing generic matrix-vector multiplication is essential for both classical and quantum information pr…
Improving fermionic variational quantum eigensolvers with Majorana swap networks
