We're utilized to everybody having a computer, whether it's a laptop or a smartphone. At the beginning of the era of computers, while inactive working on lamps, there were very fewer specified ones. I remember erstwhile I studied, it was in Świerk, and in the Physics Department we only had a link to it. most likely the same thing will happen at first with quantum computers. They will be owned by Microsoft, IBM, Google, Musk, Pentagon, various Chinese laboratories, and may besides be able to construct a fewer in Europe.
There is no large chance that in Poland we will construct a quantum computer ourselves, but components as much as possible. I myself work in a laboratory where laser diode systems are created to halt strontium atoms, which is simply a prerequisite for the operation of certain quantum computers.
Some kind, due to the fact that qubits can be realized with not only immobilized ions, but besides polarized photons, electrons, superconductive circuits, colour centers in the diamond, etc. Wherever "something" can take 2 states simultaneously (e.g., spin up and down), this "something" can be a qubit.
Most likely, the method of trapping strontium atoms will win, but this is not entirely certain.
What is in Poland's interest?
Yeah, to make European quantum computer technologies with the largest Polish participation. It takes billions of Euros and immense human knowledge. This cognition is based on the appropriate cooperation of hundreds of people. Can we organise them in Europe? Do we have money for this? I have doubts.
We (means the Institute of Higher force PAS, TopGaN and Faculty of Physics of the University of Warsaw) participate in the European Q-Planet programme:European pilot line to build and industrialize neutral-atom quantum chips. The fantastic programme, only the budget is 50 million Eur for 3 years for 40 partners. These are peanuts for that technology. 50 billion Eur would be much more appropriate. That's what American companies and Chinese laboratories spend.
Returning to the number of quantum computers in the world, they will first be in these American and Chinese centres, then they will appear in Germany, France and England, and yet in Poland. We should do everything we can to make this happen as shortly as possible.
The basic questions I will be liable for in a fewer days are:
(i) How to prepare technological laboratories and companies for the coming quantum revolution?
(ii) How to prepare Polish education for this?
But that's in a fewer days.
