QuiX Quantum

Photonic quantum processors for room-temperature computing

Overview

QuiX Quantum develops quantum photonic processors and complete quantum computing systems that operate at room temperature using photons in reconfigurable silicon nitride waveguides (TriPleX) to form universal, tunable interferometers. A fabless model means they design the chips and IP in-house but contract fabrication to specialized foundries; their processors route photons through low-loss on-chip circuits to realize quantum interference. Compared with others, they emphasize room-temperature photonics, high qumode counts on compact chips, and a proven track record with large-scale processors and a DLR sale, plus cloud-based remote access. Their goal is to deliver a first-generation universal photonic quantum computer by 2026 and enable broader access through cloud services and collaborations.

Photon counting, explained.

Photon counting, explained. Optical quantum computers rely on photons as qubits to process information and perform calculations. However, while most detectors can detect light, they struggle to count individual photons. To address this limitation, Baalbergen and his team investigated superconducting nanowire detectors. These devices contain ultrathin wires that exhibit no electrical resistance at very low temperatures. Hence, once a photon hits one of these wires, it changes the wire's electrical state and produces a measurable signal. The researchers also improved the connection between the detector and its readout electronics. This reduced the signal loss and made it easier to extract information from the measurements. "We have developed a technique that allows you to distinguish between one, two and three (or more) photons (individual particles of light)," Baalbergen explained. According to the physicist, the new method also shows how certain each photon count is. "It may seem like a small step forward, but it is in fact quite a significant, fundamental step forward," he noted. "Admittedly, our detector still needs further development, but with the path we have now embarked upon, we will get there." Precise light detection. The initiative also involved Ilse Kuijf, a PhD candidate in theoretical physics at the university, and master's student Lars Seldenthuis. Instead of examining only the amplitude, the scientists also analyzed how each signal changed over time. This made it far easier to count photons accurately without the need for complex electronics. The young scientists believe that the technology could support more powerful optical quantum computers capable of tackling calculations that remain extremely difficult for conventional machines. Other potential applications include studying chemical reactions and developing new molecules and materials. Baalbergen noted that optical quantum computers have an advantage as most of their components work at room temperature. "So we don't need a large cooling system to lower the temperature to near absolute zero," he said. "That saves a lot of money and time." With that in mind, superconducting nanowire detectors still require extremely low temperatures. Baalbergen also cooperated with Dutch firm QuiX Quantum, which launched its first working optical quantum computer prototype in summer 2026. He expects similar photon-counting detectors to be used in the company's future systems. "With this detector, the quantum computer will soon be able to perform calculations with even greater accuracy," Baalbergen concluded in a press release.

SENKO and PHIX create common interface for photonic modules.

SENKO and PHIX create common interface for photonic modules. PHIX Photonics Assembly and SENKO Advanced Components are establishing a standardized, detachable fiber connection for photonic multi-chip modules, a move designed to ease manufacturing challenges and improve long-term serviceability. This collaboration positions PHIX in Enschede, Netherlands, as a European Centre of Excellence for this emerging technology, which supports scaling artificial intelligence infrastructure and high-performance computing. Learn Physics "The industry needs solutions that connect precision assembly, package-level testing, system integration, and long-term serviceability," says a Vice President at SENKO. By combining PHIX's packaging expertise with SENKO's Micro Prism Array technology and 6DoF alignment processes, the companies aim to create a repeatable optical interface throughout a product's lifecycle. SENKO's Micro Prism Array & SAM-T enable repeatable optical interfaces. SENKO's Micro Prism Array technology directly addresses a critical challenge in photonic module manufacturing: maintaining consistent optical performance throughout the product lifecycle. This new architecture utilizes detachable fiber connectivity, a departure from traditional permanently attached interfaces, and allows for repeatable alignment during assembly, package-level validation, and system integration. The system uses SENKO's SEAT receptacles and SAM-T, or SENKO Alignment Master-Testing, alongside precision 6DoF alignment processes to establish a common optical reference point throughout the supply chain. This collaborative effort between SENKO and PHIX Photonics Assembly isn't simply about improving manufacturing consistency; it's about enabling future serviceability, the company says. By separating photonic packaging from permanent fiber attachment, the design facilitates inspection, diagnostics, and component replacement without requiring a complete optical assembly redesign. Learn Physics This approach is particularly relevant as optical engines move closer to application-specific integrated circuits, or ASICs, where maintaining operational flexibility is paramount. "As optical engines move closer to the ASIC, the industry should keep the operational flexibility that made pluggable optical transceivers so successful," said a company representative. "By combining advanced photonics packaging with a repeatable, detachable optical interface, this collaboration helps bridge the gap between CPO performance requirements and the practical needs of testing, maintenance, and long-term serviceability." PHIX, headquartered in Enschede, Netherlands, contributes to realizing this architecture through its expertise in advanced photonics packaging, according to SENKO. PHIX's Characterization Package is already utilized in a photonic quantum processor, demonstrating the practical application of its packaging capabilities. The company's involvement in EU projects like LOLIPOP, POLYNICES, PATTERN, and photonixFAB further underscores its commitment to advancing photonic manufacturing technologies and establishing scalable approaches for multi-chip modules. PHIX establishes European center for detachable fiber assembly & PIC packaging. PHIX Photonics Assembly's newly established role as a European Centre of Excellence focuses on a critical, previously unaddressed aspect of photonic module manufacturing: standardized, detachable fiber connections. This specialization goes beyond simply assembling photonic integrated circuits, concentrating instead on the interface between those circuits and external fiber optics, a distinction vital for scaling production. SENKO Advanced Components' Micro Prism Array technology forms the core of this connection, enabling precise alignment and repeatable performance throughout a device's lifespan, the firm reports. The collaborative framework between SENKO and PHIX delivers a system where optical components undergo alignment during assembly, validation at the package level, and verification during system integration, all using the same detachable interface. This contrasts sharply with traditional methods requiring permanent fiber attachment, which complicates diagnostics and repair. The use of SENKO's SEAT receptacles and SAM-T further refines this process, providing a standardized method for connecting and testing modules. Learn Physics Founded in 2018 and headquartered in Enschede, PHIX has rapidly become a key player in advanced photonics packaging, with its Characterization Package already integrated into a photonic quantum processor from QuiX Quantum. Jeroen Duis, PHIX's Chief Technology Officer, explains that by decoupling packaging from fiber attachment, the architecture allows for inspection, diagnostics, replacement, and maintenance without necessitating a complete redesign. Visitors to ECOC 2026 can explore this technology firsthand at the SENKO (booth #1005) and PHIX (booth #1051) exhibits.
