Ephos is a producer of glass-based photonic chips. In September 2024 it raised $8.5 million in seed funding and opened the world's first facility dedicated to designing and producing glass-based photonic chips, located in Milan.

The company's proprietary technology builds glass-based photonic chips with best-in-class performance for signal loss, a critical advantage in constructing quantum computers. Its 3D design and manufacturing capabilities open up new scaling opportunities and computational modes that improve system performance. The funding round was led by Starlight Ventures, with participation from Joe Zadeh, former Vice President at Airbnb, Diego Piacentini, former Senior Vice President at Amazon, and Simone Severini, General Manager of Quantum Technologies at Amazon Web Services. Glass-based photonic chips also have applications beyond quantum computing, including data centers, where they can reduce energy footprints. In 2025, Ephos secured a EUR 41.5M grant under the EU Chips Act, the first awarded to a startup, to build Fab-2, a glass-based photonic chip manufacturing facility in Italy.

PhotonPath develops proprietary silicon photonics chipsets and plug-and-play modules for quantum applications. Douglas Aguiar (CEO) and Emanuele Guglielmi (CTO) founded the company during their PhD and post-doc research at Politecnico di Milano. It spun off from the university and was nurtured within the PoliHub deep-tech hub.

The company raised a 5.1 million euro Series A in 2025 to scale manufacturing. Its patented technology supports compact, energy-efficient quantum communications, sensing, and computing. PhotonPath operates R&D labs and manufacturing facilities in Milan and Trento, with applications that extend to hyperscale data centers, telecom networks, and aerospace systems.

Planckian is a Pisa-based quantum technology startup that emerged as a joint spinoff from the University of Pisa and Scuola Normale Superiore, working on solid-state energy technology based on quantum mechanics. Its research uses quantum effects to enable qubits to reach collective higher energy states, with potential applications in sustainable energy, including quantum batteries capable of indefinite energy storage. The company also develops superconducting quantum computers with global control schemes, combining its quantum battery research with quantum computing hardware development.

In July 2023, Planckian secured 2.7 million euros in pre-seed funding led by CDP Venture, Exor Ventures, and private investors to move beyond traditional electrochemical approaches in energy technology. Founded by quantum researchers including Marco Polini, Chief Scientific Officer, and Vittorio Giovannetti, Executive Scientific Advisor, Planckian reflects Italy's push into quantum energy applications and next-generation quantum processor architectures. In June 2025, the company signed partnerships with the University of Naples Federico II and its QTLab quantum computing center to test and validate its scalable superconducting processor designs, which cut control wiring by letting multiple qubits share a single control line. This processor work has become the company's primary focus. Update 2026-05-14: Seth Lloyd has joined Planckian. Source: https://quantumzeitgeist.com/seth-lloyd-joins-planckian-landmark/

QSENSATO is a University of Bari spin-off founded in 2024 by Gianvito Lucivero, Annalisa Volpe, and Domenico Tulli. It develops chip-based quantum sensors for ultra-precise measurements.

The company's atomic-photonic technology supports high-sensitivity detection of electric and magnetic fields, with applications in medical imaging, geophysics, infrastructure monitoring, and GPS-free navigation. Its core technology uses atomic-photonic chips that exploit quantum interference effects in rubidium vapor. Dr. Lucivero earned his doctorate in Photonics at ICFO Barcelona in 2011, completed postdoctoral research at Princeton University, and is now a professor and researcher at the University of Bari specializing in quantum sensing.

In May 2025, QSENSATO raised EUR 500,000 in pre-seed funding from LIFTT and Quantum Italia. The company took second place in Start Cup Puglia 2024 and received honors at the Talentis-GIStartup Award in Capri. The funding supports prototype development, entry into the European and U.S. markets, and pilot deployments.

Rotonium is an Italian deep-tech startup founded in 2022 that develops single-photon qudit technology for room-temperature quantum computing. It secured EUR 1 million in seed funding led by Galaxia and CDP Venture Capital to advance the technology.

The company builds photonic quantum accelerators that let quantum computers run at room temperature, which allows for compact systems usable on Earth, in the air, and in space. Its technology is designed to operate in energy-constrained environments such as space, and Rotonium focuses on quantum computing for space and edge applications where cryogenic quantum computers are impractical. The company plans to work with universities and research centers on next-generation quantum processing, and its room-temperature single-photon qudit approach is a distinct architectural path from superconducting and trapped-ion designs, aimed at specialized aerospace and edge computing markets.

In March 2026, the company announced that CEO Roberto Siagri would present at the Quantum Computing in Life Sciences conference in Milan on April 16, 2026, covering photonic quantum accelerators for pharmaceutical molecule development and genome analysis. Update 2026-03-17: Rotonium demonstrated how its photonic quantum accelerators can integrate into life science workflows for complex molecule development and genome analysis.
