Australia creates a quantum PC that works at room temperature

That the quantum PC is the future of computing is obvious that we surely have in mind, but without going to unrealistic scenarios more typical of Hollywood, the reality is that we are only at the beginning of the abyss that separates us from everyday life with this guy of systems. Australia has achieved a small step towards the normal implementation of a quantum pc to use, making it work at room temperature. How have they achieved it?

Due to the nature of quantum computing and the capabilities of new systems and PCs that host it, processors being created today have the biggest drawback in their own cooling. What Pawsey’s team has achieved for their new supercomputers is really interesting because although we don’t know the power as such, they manage to make it work without liquid nitrogen.

The first quantum PC at room temperature thanks to diamond

An emerging company more typical of a startup than a super company has been in charge of achieving what no supercomputing giant has achieved. Quantum Brilliancehalfway between being German and Australian, is the first to have achieved this fact based on a new theory for quantum accelerators thanks to the use of diamonds as such.

The novelty is not the use of diamond per se, this is not new since many of the IBM systems use them, the novelty is in the use of a type of diamond that has a particularity: it has lost an atom in its structure. molecular and in exchange a nitrogen atom has been implanted, which modifies its properties and helps reduce the so-called decoherence times.

They have called this technique vacant nitrogen and it is something that had been studied for years and is now a reality.

It is this fact that allows confocal microscopy and thanks to a conventional fluorescent microscope to illuminate and show a beam of light with useful photons in the three base states that can represent the energy for any operation with Qubits.


Therefore, when speaking of these three states (s=0, s=-1 and s=1) we have to talk about generated energy, which is always very high and thanks to the NV in diamond, passing the electrons from an excited state (E) to a base state (A) can be done with a much lower energy expenditure, and thereby cooling the system in a conventional way.

Note that each step from E to A is a logical operation performed by each qubit. Although there is not much more data, what we do know is that Quantum Brillance has taken all this to a new level and its goal is now to include hardware and software stacks in HPE Setonix data centers, thus creating a high-end multi-computer system. and low energy consumption, thus being much more efficient.


As for the power that it is capable of developing, the company has not offered specific data, but if it is currently being implemented it is because the figures, despite being lower than those of its competitors, will represent, as a whole and in exascale, a jump that Until now it had not been achieved.
