Stream architecture
A million computations, each in its own stream
Every Compu Quanti computer is a stream processor. Before each compute cycle, every stream is given its own quantum resources, so thousands to over a million calculations run side by side without interfering. When a stream finishes, it registers its Feynman state and commits its result to qubit memory.
Spintronics, near absolute zero
Computing with the spin of a single electron
Our spintronic processors hold each computation in the spin of electrons, using atoms from hydrogen to neon. To keep those fragile states perfectly still, the core sits in a gold-plated cryostat at 0.01 kelvin, colder than deep space, while the plant around it draws megawatts of power.


Quantum photonics
Light is the only way in and out
No ordinary wire can reach a core this cold without warming it. Our advanced quantum photonic interface carries data in and out on entangled light through optical fiber, and links Compu Quanti systems to one another with our ultra-secure quantum link.
The D-Series
Four masterpieces. From €1 billion.
Named for the masters of our city. Every model runs the same stream architecture and quantum atomic assembly code, so software scales from the first stream to the millionth.

Our most advanced system
Model E1 Leonardo
The Quantum Conscientious AI Entity Super Computer
Designed for implementing super AI Entities capable of supreme super intelligence, and fully interfaced to every Automa software package. The E1 does not run programs. It hosts a mind.
- Entity Core. Sixteen million streams dedicated to a single, continuous AI Entity, with every atom holding full quantum superposition through every cycle and persistent memory that never resets.
- Conscience Core. A dedicated governing processor weighs every decision against the Entity’s ethical charter before it acts. This is what makes the E1 conscientious, and the reason governments trust it.
- Launched and controlled by Automa. The Entity is brought to life, supervised and commanded by Automa Entity, the AI Entity platform from Automa.
- Entity AI design intelligence. The Entity drives Automa Physics, Chemistry, Aerospace, Pharmaceuticals, Semiconductor Physics and Genetics directly, inventing, simulating and refining designs on its own.
- Holographic presence. The E1 interfaces to holographic 3D displays, presenting the Entity as a lifelike human person you can talk to and interact with just as you would with anyone else, face to face and in real time.
- Photonic sensorium. High-bandwidth quantum photonic links let the Entity see, hear and converse with its operators in real time.
- Commissioned, not sold. Each E1 is built to order in Florence and delivered with a Compu Quanti team stationed on site.

Every Compu Quanti computer runs Automa
All D-Series systems are certified for the premier software suites from Automa, the world’s leading software design company. Written in quantum atomic assembly code, each Automa package spreads its work across every available stream, so the same simulation that takes a D2 a day runs on a D5 in minutes. Each package is licensed from €250 million.
