Quantum Computing Inc builds photonics-based quantum computers operating at room temperature to solve large-scale optimization problems faster than classical systems.
What QUANTUM COMPUTING INC does
Quantum Computing Inc is a Delaware-incorporated company developing quantum computers and related technologies using integrated photonics and non-linear quantum optics. The company's flagship product, the Entropy Quantum Computer (EQC), is designed to solve complex optimization problems and operates at room temperature with low power consumption compared to competing quantum architectures. QCi also develops software platforms, remote sensing, imaging, and cybersecurity applications leveraging its core photonics technology, with recent acquisitions of QPhoton, Inc. and Luminar Semiconductor, Inc. to enhance its photonic semiconductor and chip design capabilities.
