Making a qubit is not easy at all. There are various types, but currently some of the most developed technologies are superconductors, ion traps and neutral atoms. Intel, which is one of the big companies involved in the development of quantum computing, has opted for the production of silicon qubits with a very clear purpose: to take advantage of its experience in the manufacture of high-integration semiconductors to produce quantum chips.

Each of the qubits manufactured by this company is encoded on the spin of an electron housed on a silicon substrate. Spin is a quantum magnitude, and we can imagine it as a characteristic spin of the elementary particles on themselves that has a fixed value and that, together with the electric charge, is one of the intrinsic properties of these particles. Intel manipulates the spin of its qubit electrons using magnetic fields.

One of the biggest challenges researchers at this company have been working on for years is finding a way to use the photolithography equipment they use to make their most advanced semiconductors in the production of quantum processors. However, in reality the real challenge is to optimize the use of the entire surface of a 300mm silicon wafer. And Intel has just taken a very important step forward that allows you to touch this milestone with your fingertips.

Silicon quantum processors with millions of qubits are closer

The resources that Intel is devoting to the development of silicon qubits are paying off. In fact, a few hours ago he confirmed that his researchers at the R&D center he has in Hillsboro, Oregon, have managed to use extreme ultraviolet photolithography (UVE) equipment to produce functional qubits in 95% of a silicon wafer.

There is no doubt that this is fantastic news. And it is because this performance is significantly higher than what Intel had achieved so far. However, the most interesting thing is that this achievement invites this company to seriously flirt with the idea of catapult scalability of its quantum chips, which currently have a few tens of qubits, to integrate thousands and even millions of qubits inside them.

This one that still has this discipline ahead of it.

In fact, some experts, including Ignacio Cirac, who is one of the founding fathers of quantum computing, believe that to make error correction possible and solve symbolic problems it is necessary to have several million qubits. Probably even hundreds of millions of qubits. Right now we are a long way from achieving this milestone, but Intel’s achievement invites us to look forward to this horizon with optimism. It may not be as far away as these figures seem to reflect.
