Photonic

Photonic Inc. focuses on developing large-scale, fault-tolerant, and distributed quantum computing and networking platforms. The company's unique approach combines optically-linked silicon spin qubits with a native telecom networking interface, enabling efficient quantum error correction and scalability.

Photonic's architecture harnesses the manufacturability of silicon and the inherent connectivity of optical fiber networks. By leveraging silicon spin qubits, each qubit is equipped with an optical photonic interconnect operating at telecom wavelengths. This approach allows for on-chip and off-chip connectivity, facilitating the distribution of quantum entanglement and enabling modular, distributed quantum computing.

In May 2024, Photonic achieved a significant milestone by demonstrating entanglement distribution between physically separated silicon spin qubits housed in different cryostats. Through a series of experiments, the company successfully entangled the qubits using photons transmitted through a fiber-optic cable and executed a remote quantum logic gate sequence, known as the teleported CNOT gate, between the separated qubits.

This breakthrough showcased Photonic's ability to operate a quantum computer in an industrial setting, paving the way for long-distance quantum communication and scalable, fault-tolerant quantum computing. The company's architecture offers the potential for synergies in quantum communications, networking, and distributed computing across various applications, including materials science and drug discovery.

Key customers and partnerships

In November 2023, Photonic announced a strategic collaboration with Microsoft to co-innovate on quantum technologies and accelerate scientific discovery. The partnership aims to integrate Photonic's quantum networking capabilities into the global infrastructure of the Microsoft Azure cloud, providing customers with access to Photonic's hardware when available.

Photonic is also collaborating with Zurich Instruments, a Swiss company specializing in quantum control solutions. Zurich Instruments' Quantum Computing Control System (QCCS) is being utilized by Photonic for the development of its quantum technology, offering high-quality signal generation, exceptional phase coherence, and proven scalability.
