Rotonium

Rotonium is an Italian deep-tech startup founded in 2022 that secured €1 million in seed funding led by Galaxia and CDP Venture Capital to advance single-photon qudit technology for room-temperature quantum computing. The company develops silicon photonics components that enable quantum computers to operate at room temperature, allowing for compact, versatile systems usable on Earth, in the air, and in space. Rotonium's technology is designed to operate in energy-constrained environments like space, positioning the company as a potential leader in edge quantum computing applications. The company focuses on quantum computing for space and edge applications where traditional cryogenic quantum computers are impractical, with plans to collaborate with universities and research centers to advance next-generation quantum processing capabilities. Rotonium's room-temperature approach using single-photon qudits represents a distinct architectural path from traditional superconducting and trapped-ion approaches, targeting specialized applications in aerospace and edge computing markets.
