In collaboration with partners, QCi is developing custom quantum cybersecurity hardware as well as proprietary networking and security protocols for: 1. Quantum Networks / Quantum Internet Quantum Random Number Generator (Launched April 2023) Our patented QRNG is photonic based, capable of generating non-repeating number sequences, can generate truly random numbers of various probability densities and correlation properties to serve many different applications including security, modeling, and finance. Quantum Key Exchange/Distribution dQKD is QCi's high dimensional quantum key distribution protocol. dQKD is an entanglement- based quantum key exchange method which uses multi-dimensional quantum keys and can be easily integrated with existing telecommunications networks. d-QKD has the added benefit of not requiring quantum error correction. Quantum Authentication Our qAP is quantum authentication protocol that utilizes zero-knowledge proofs. Using pre-shared symmetric keys, qAp-0 enables authentication between communicating parties without revealing full or partial keys to the possibility-not- trustworthy third parties while eliminating the need for complex computation. co IR PS Pulses MM Disordered Waveguide Scrambling Rings Quantum Computing Inc.

Ci Innovative Quantum Solutions Company NASDAQ: QUBT 13#14IMAGING - IMPRESSIVE APPLICATION AND FUTURE LAUNCH QCi offers One of the most exciting opportunities in development leverages the ability to count single photons and filter their associated wave functions precisely to obtain optical imaging through otherwise opaque and dense materials. Our core technology efficiently generates, conditions and measures single photons enabling us to create high-resolution, low-cost devices for biomedical imaging. Targeting both the commercial and defense industries, our imaging platform is able to extract a multitude of information from single and few photon light using temporal gating. With the aid of single-photon sensitive cameras and mode-selective image conversion, we are able to obtain optical tomograms and 2D Raman images from deep inside human tissue. The ability to rapidly analyze these images with high sensitivity adds new, highly sought after, diagnostic capabilities.
