Groundbreaking Advancement: Debut of the World's First Blend of Quantum and Photonic Chip Technology
Breakthrough in Quantum Technology: World's First Hybrid Quantum-Photonic Chip Announced
In a groundbreaking development, an interdisciplinary team from UC Berkeley, Boston University, and Northwestern University has successfully created the world's first chip integrating quantum light sources and control electronics on a single silicon chip. This milestone was reported in mid-2025 and published in Nature Electronics.
The hybrid chip, fabricated using a standard 45-nanometer CMOS semiconductor process, is compatible with existing commercial semiconductor manufacturing infrastructure. It combines quantum photonic components (photon pair generators called microring resonators) with electronic control circuits that provide continuous self-tuning and stabilization on-chip, eliminating the need for bulky off-chip equipment.
Each silicon chip hosts an array of "quantum light factories", twelve independent quantum light sources that are powered by laser light and depend on microring resonators to generate photon pairs crucial for quantum applications. The chip, about 1 mm² in size, integrates 12 microring resonators, each capable of generating streams of correlated photon pairs.
The design includes embedded photodiodes, miniature heaters, and control electronics that monitor and stabilize the quantum light generation in real time, allowing all resonators to work synchronously and reliably. This hybrid integration is a significant step toward scalable silicon quantum photonic systems and “quantum light factory” chips that could be mass-produced using standard semiconductor foundries.
The team, led by PhD student Daniel Kramnik at UC Berkeley, emphasizes that this is a foundational step on the long path toward practical quantum computing, communication, and sensing technologies. They highlight the importance of their interdisciplinary approach for moving quantum systems from the lab to scalable platforms.
Meanwhile, IBM Quantum is building the world's first large-scale quantum computer, IBM Starling, expected to deliver to clients in 2029. IBM Starling will be 20,000 times more powerful than existing quantum computers and "would require the memory of more than a quindecillion of the world's most powerful supercomputers."
In the realm of venture capital, the startup Ayar Labs, which focuses on silicon photonics, secured $155 million in funding from AMD Ventures, Intel Capital, and Nvidia at a valuation of $1 billion.
IBM's quantum computing goals extend beyond Starling, with Blue Jay, the second-generation fault-tolerant quantum computing ISA, not expected to arrive until after 2033. IBM and Moderna have already used the IBM Quantum Heron processor to model mRNA structure using quantum simulation with the aim to "improve human health."
Quantum technology, consisting of quantum computing, quantum communication, and quantum sensing, could generate $97 billion in revenue worldwide within the next decade. The successful development of the hybrid electronic-photonic quantum system-on-chip marks a significant step towards realizing this potential.
