An objective, verifiable account of what quantum technology delivers.
send messageIn 1964 the Soviet astronomer N. S. Kardashev, writing on how civilizations might transmit information across space, classified them in three types by the energy they harness: a planet’s, a star’s, a galaxy’s.
Each step is a leap: from Type I to Type II the energy grows about a hundred trillion times, and from Type II to Type III about a hundred billion times.N. S. Kardashev, “Transmission of Information by Extraterrestrial Civilizations”, Soviet Astronomy 8, 217 (1964) (opens in a new tab)
We are working toward one complete system that integrates conventional computers, AI, machine learning and quantum technology.
Along the way, we are closing gaps in quantum technology by developing simulation software for superconducting components and error-correction technology.
We hold our own technology to the standard we apply to others’ claims. The system must be reliable, parallel, programmable, debuggable and predictable.
Results verified under a stated model with the rules fixed in advance: the model sets the number.
Quantum readiness: use cases, timing and risk, encryption included.
Inventions from universities and laboratories, matched with capital and companies.
Briefings, education and ongoing monitoring of quantum technology for decision-makers.

Classical computers do most of the work, quantum processors take the parts where they add value, and machine learning has already helped a quantum computer correct its errors, in a 2026 demonstration.
