Pioneering Massive Scaling: Unlocking 1-Million-Qubit Quantum Computing QuamCore is developing a quantum processor with one million qubits, all housed within a single cryostat. By leveraging established superconducting qubits and integrating them with a digital superconducting controller, QuamCore has designed a complete architecture that supports one million qubits in a single cryostat—surpassing the traditional approach, which is typically limited to thousands of qubits per cryostat. The goal of one million qubits stems from a widely shared view in the quantum computing community: this scale marks the threshold at which quantum computers begin solving real-world problems rather than merely demonstrating the technology’s potential. Through an architecture-first strategy, we methodically mitigated risks and developed a fully realized solution, which we are now bringing to production.

Commcrete develops ultra-compact satellite communication systems engineered for defense, public safety, and commercial users in austere, denied, or mobile environments. Our plug-and-play, low-SWaP devices deliver reliable, stealthy L-band connectivity for secure voice, encrypted text, asset tracking, and Blue Force Tracking - across all weather, all terrain. Unlike traditional SATCOM, Commcrete’s solutions do not rely on conventional satellite protocols, ground stations, or constant signal transmission - enabling resilient performance with stealthy signal profiles, ideal for covert and on-the-move operations. Leveraging L-band GEO satellite channels and a proprietary protocol stack, Commcrete ensures real-time, energy-efficient communications even when GPS or terrestrial networks fail. Capabilities include S-COTM, real-time multi-channel L-band SATCOM, multi-band to L-band conversion, and mission-critical C4I. With a 32 dB link budget in SOS mode and form factors compact enough to wear, mount, or integrate, Commcrete systems are proven in high-stakes global deployments—and scaling rapidly.
