Problem

Quantum computers can now contain thousands of qubits, but existing control hardware—primarily free‑space optics—lacks the stability, density, and manufacturability needed to address all qubits reliably. This control bottleneck limits the ability to scale quantum systems across different qubit modalities such as superconducting circuits, trapped ions, neutral atoms, and photonic qubits.

Solution

Linq Photonics delivers photonic integrated control systems that replace bulky free‑space optics with compact, chip‑scale modulators. Their devices provide up to 60 dB extinction and support more than 100 independent operations, enabling precise phase and amplitude modulation for large qubit arrays. By offering custom wavelength coverage from 400 nm to 1700 nm, the platform can be tailored to the optical requirements of diverse quantum technologies. Integrated splitting, filtering, and multiplexing functions further reduce system complexity and improve signal stability. Rapid prototyping across multiple photonic platforms allows quantum engineers to iterate designs quickly and integrate control hardware directly into scalable quantum processors.

Target Audience

Primary customers are quantum engineering teams developing superconducting, trapped‑ion, neutral‑atom, or photonic quantum processors that require high‑performance, scalable optical control infrastructure.
