Quantum machines for a brighter future

hardware option 3

At Quantum Computing Inc. (QCi), we are pioneering the production of photonic hardware solutions using non-linear quantum optics, enabling innovative solutions in the fields of quantum computing, machine learning, cybersecurity, and much more, including the new Dirac-3 entropy quantum computer.

Our technology

The QCi core technology is based upon leveraging light and its quantum mechanical properties as a versatile tool that, when manipulated correctly, can be used as a component for many different applications.

Quantum computing

Dirac systems are portable, low-power, and room-temperature qubit and qudit entropy quantum computers (EQC). A Dirac system solves problems of Objective Function Minimization and Maximization for binary and integer optimization by finding the ground state of a complex system with many intercorrelated variables.

Technology - Photonic

Reservoir computing

Photonic reservoir computers are opto-electronic time delay feedback reservoir devices, delivering a remarkable 1.25G nodes per second and boasting the capacity for up to 60,000 virtual nodes. This compact powerhouse is tailor-made for intricate time series analysis.

Entanglement Source


QCi is proud to present a new and powerful hardware-driven methodology for a Quantum Zero Knowledge Proof (QZEKP) protocol for privacy-preserving computation, authentication, and verification.
