Technology - SaxonQ

Quantum > Digital

Why do quantum computers surpass traditional computers in their computing power? This is due to two quantum mechanical phenomena that contradict our everyday experiences: superposition and entanglement, which allow for the simultaneity of different states and the defined connection of multiple particles over distance. SaxonQ utilizes these properties with industry-ready NV technology in a quantum computer.

Superposition

A digital computer operates with 0s and 1s, representing two clearly defined states: either/or. In contrast, a qubit, the bit of a quantum computer, can be both 0 and 1 simultaneously, as well as everything in between – known as the "Schrödinger's cat state." The cat is both dead and alive at the same time until we check. Until the qubit is measured, the quantum computer can perform calculations in unobserved steps (so-called gate operations) and is therefore capable of exponentially more computing power than traditional computers.

Entanglement

The second quantum mechanical phenomenon is entanglement. In this case, two or more qubits are connected and react to each other – without any visible contact being necessary. This can also occur over larger distances. Albert Einstein referred to this phenomenon as "spooky action at a distance" and doubted its possibility. Still unimaginable today, yet well understood and usable, entanglement, along with superposition, forms the key functionality of the SaxonQ quantum computer.

NV Technology makes the Quantum Computer suitable for Everyday Environments

We are one of the few companies to integrate these phenomena into an industrial-grade computer that operates at room temperature and without extensive peripheral equipment – whereas other systems must be cooled to -273 degrees Celsius, nearly reaching absolute zero, and are sensitive to environmental influences. The key to this is diamond, the ideal material for our highly precise, time-stable qubits.

The SaxonQ diamond chip contains billions of carbon atoms. The qubits, in turn, are created from individual nitrogen atoms that we insert into the diamond lattice. Each nitrogen atom now forms an NV qubit (Nitrogen-Vacancy center) along with a neighboring missing carbon atom. Nearby atomic nuclei at the NV center contribute additional qubits to the quantum processor.

Advantages of NV Technology

room-temperature operation

The NV centers are decoupled from the "warm" diamond lattice, and only the qubits are cooled using lasers. This allows the system to operate reliably at room temperature.

Mobile

Compact size, lightweight, low energy consumption – the computer can be operated anywhere there is a power outlet, as long as it remains dry.

Sustainable

Low energy consumption and efficient resource utilization make NV technology extremely sustainable, especially considering the immense computing power it provides.

Multi-Qubit

The NV technology enables fast and simple gate operations for entanglement. In multi-qubit operations, each NV center simultaneously controls multiple neighboring core qubits.

Scalable

The NV centers are arranged in arrays, making them highly scalable. Additionally, only a few control lines are needed for complete control.

Multicore – 80 Qubits

In our multicore computers, multiple NV chips work simultaneously to accelerate your applications and reduce quantum errors. Currently, our standard offering includes an 80-qubit multicore system.

Qiskit compatible

The computers can be programmed using Qiskit, OpenQASM, and our own quantum gate language. Let us know which code you would like to run on our chips.

Industry Ready

The SaxonQ quantum computer operates wherever you need it – in your factory, office, or laboratory.

Scalable Engineering ready for Batch Production

The SaxonQ qubits are produced using a patented manufacturing process that involves nitrogen implantation and sulfur co-implantation in diamond. This allows for the creation of large qubit arrays with nanometer-level precision and high yield.

The manufacturing process of the chips is derived from established practices in the semiconductor industry, making it easily scalable.
