Quantum computer-generated holography

Hologram calculations pose a significant challenge for future holographic displays with extensive fields of view and wide viewing angles. Classical computers may encounter difficulties with these owing to immense computational demands. This study introduces quantum computer-generated holography (QGH) as a viable solution. QGH employs a point-cloud algorithm in which point-cloud data are represented by the superposition states of qubits, and lightwave interactions on the hologram are calculated using principles of quantum mechanics. QGH can accelerate hologram computation by a factor of $10^6$ in a 1 tera-pixel hologram from 1 tera-object points, compared to classical computer-generated holography. The study discusses advantages, limitations, and future directions.
