Xanadu Quantum Technologies
Xanadu Quantum Technologies Inc., a world leader in photonic quantum computing, has announced a significant expansion of its strategic partnership with Singapore’s Agency for Science, Technology and Research (A*STAR). This move is expected to support Asia’s rapidly expanding quantum technology landscape. A Memorandum of Understanding (MoU) that intends to significantly enhance the research and development pipeline for next-generation quantum technologies formalizes the renewed and expanded collaboration. The long-sought objective of fault-tolerant quantum computing is the specific emphasis of this strategic partnership.
The deal strengthens Xanadu‘s long-standing, fundamental partnership with ASTAR’s Institute of Microelectronics (IME), a renowned leader in integrated circuit and semiconductor research. Crucially, the new extension includes two more important ASTAR units: the Quantum Innovation Centre (Q.InC) and the Institute of High Performance Computing (IHPC). Through the integration of hardware fabrication knowledge, computational modelling, and innovation commercialization into a single, coherent quantum project, this multi-institutional engagement signifies a thorough, full-stack strategy.
The MoU’s overarching strategic objective is to create long-term research partnerships and aggressively investigate the feasibility of establishing cooperative quantum laboratories and fully functional facilities within Singapore.

Leveraging Synergy for Next-Generation Devices
The collaboration is a powerful synergy that combines ASTAR’s extensive governmental and technological capabilities with Xanadu’s well-known proficiency in photonic quantum computing, including its specialized software platforms and algorithms. ASTAR provides vital skills including integrated photonics design, sophisticated packaging, and the investigation of new quantum materials that are necessary for producing next-generation quantum devices. The partnership is now at the forefront of the worldwide race to move quantum systems from research prototypes to enterprise-ready, commercially viable devices with this combination.
Photonic quantum computing, a highly strategic approach, is the technical focus. In contrast to trapped-ion or superconducting methods, which need cryogenic (very cold) conditions, Xanadu’s system uses photons, or light particles, as its basic quantum bit, or qubit. The capability for room-temperature functioning and the capacity to take advantage of the current semiconductor and optical communication infrastructure are two of the photonic approach’s many intrinsic advantages.
In a photonic system, optical components like beam splitters and phase shifters embedded into silicon chips are used to perform quantum gates. Quantum information is encoded in the characteristics of light. Integrated photonics is the name of this field. The cooperation aims to tackle the fundamental problem of producing, modifying, and detecting these quantum states of light at scale with high reliability while minimizing faults that are inevitable in any physical system. Through a number of crucial, well-defined projects, the enlarged partnership is specifically intended to address these scaling and stability issues in order to produce the next wave of quantum research.

Deep Dive into Core Research Pillars
The four main technological pillars that support the enlarged field of research are essential to achieving fault tolerance:
- Error Mitigation for GKP State Generation: This technically challenging topic focusses on error mitigation for GKP state generation. GKP states are continuous-variable, highly specialized quantum states. These states are thought to be essential for building fault-tolerant quantum computers with photonic platforms. The ability of a quantum computer to identify and fix mistakes before they happen is known as fault tolerance, and it is a requirement for resolving issues that are pertinent to industry. With the goal of making these crucial quantum resources stable and repeatable enough for intricate algorithms, the collaborative effort will make use of A*STAR’s sophisticated fabrication facilities and integrated photonics expertise to enhance the fidelity and robustness of GKP state generation.
- Development of Quantum Light Sources: The quality of a photonic quantum computer’s light source is a fundamental constraint on its performance. The collaborative creation of improved quantum light sources is the second important topic. The squeezed light, a non-classical state that shows less noise in some measured variables, is a key component of Xanadu’s systems. The goal of this research is to design integrated light sources that are highly stable, scalable, and efficient in order to provide the high-quality quantum resources needed for high-speed quantum computation.
- Integrated Quantum Connectivity and ASIC Integration: A strong and intricately linked network of quantum components is necessary for scaling up quantum computers. The collaboration will use custom ASIC (Application-Specific Integrated Circuit) integration in conjunction with cutting-edge integrated photonic chips to develop novel solutions for quantum connection. The goal of this work is to develop a dense, repeatable, low-loss “plumbing” system on a chip that can efficiently transport quantum data throughout a big processor. In order to bridge the gap between the quantum processor and the conventional control system, high-speed, low-latency control and readout of the quantum state depend on the integration of bespoke classical electronics (ASICs).
- Exploring Quantum Computer Hosting in Singapore: The last strategic pillar is investigating the possibility of hosting photonic quantum computers in Singapore. This initiative shows a commitment from both sides to develop concrete quantum infrastructure in the area and provides a direct route from research to commercial deployment. Research institutes, governmental organizations, and business partners throughout Southeast Asia would have direct access to state-of-the-art hardware if this investigation resulted in the construction of a joint facility, solidifying Singapore’s status as a significant regional centre for quantum computing.
Accelerating the Path to Fault Tolerance
“The extended partnership is specifically meant to accelerate the company’s path towards delivering fault-tolerant quantum computers that possess the power to solve real-world problems currently intractable for classical supercomputers,” said Christian Weedbrook, Xanadu’s founder and CEO.
ASTAR’s Deputy Chief Executive, Professor Yeo Yee Chia, emphasised the Agency’s critical role and said the partnership will use ASTAR’s vast research experience and industry-standard facilities, such those at IME, to help accelerate development cycles. The goal of this strategy is to establish unambiguous routes from early quantum concepts to reliable, manufacturable solutions. In order to guarantee that the parts required for a fault-tolerant quantum computer can be consistently scaled up in a manufacturing environment rather than merely a lab, this emphasis on manufacturability is essential.
Utilising Xanadu’s targeted technical development and Singapore’s national vision for scientific excellence, the expanded relationship between Xanadu and A*STAR is a high-stakes, high-reward endeavor. This partnership is actively establishing the technical and physical foundation for a commercially feasible quantum future, one that may soon see a photonic quantum computer established as a flagship technological asset in Singapore, by addressing important areas such as integrated photonics, manufacturability, and GKP state engineering.
