Lab Equipment

The Problem

Quantum Experiments Require Unmatched Quality.

Quantum research demands equipment capable of generating and measuring quantum states with ultra-high fidelity, consistency, and accuracy. Building high-performance quantum hardware in-house is time-consuming and resource-intensive.

zerothird’s lab equipment—such as polarization-entangled photon pair sources—gives researchers plug-and-play access to precision-engineered tools, so they can focus on advancing quantum science, not assembling lab infrastructure.
