Today, startup atom Computing announced the internal testing of a quantum computer for 1.225 cubes, which will become available to customers next year. This system was a significant breakthrough for the company that previously created the system on neutral atomic cubes using only 100 cubes.
However, the high frequency of errors in operations with individual cubes makes it impossible to launch an algorithm based on the full volume of cubes without risk of failure due to error. Nevertheless, this confirms the company’s statements about the fast scaling of their technology and provides a platform for working on quantum errors. For smaller algorithms, the company plans to launch several copies in parallel to increase the likelihood of obtaining the correct answer.
As the name implies, Atom Computing uses neutral atoms as a chosen cubit. These systems depend on lasers that create a number of places that are energetically favorable for atoms. Atoms left by themselves will be inclined to occupy these places and stay there until a random gas atom encounters them.
Thanks to this system, which allows you to pack the atoms relatively densely, Atom Computing claims that the technology is well prepared for rapid scale. Unlike systems such as transmones, where small differences in the manufacture of the device lead to cubes with small differences in performance, each locked atom is guaranteed to behave the same.
These two factors, according to the company’s leaders, mean that neutral atoms are well suited for scaling to large quantities of cubes. Its initial system, launched in 2021, was a grid of 10×10 atoms.
