A group of physicists founded a startup to create a commercial quantum computer from hundreds and thousands of qubits

The other day came out of the shadows startup QuEra Computing, created by physicists from Harvard University and the Massachusetts Institute of Technology. The founders of the startup are leading physicists in the field of quantum sciences, which gives hope for a significant breakthrough in the field of quantum computing. The young company promises to create quantum computers with hundreds or even thousands of qubits in a couple of years, but it began with a story about simulating a 256-qubit system.

We have already talked about this development, which was presented in July this year. The 256-qubit platform was created at a Harvard laboratory under the guidance of a Russian and American professor. Mikhail Lukin… He, along with other leading physicists, also became one of the founders of QuEra Computing. Based on the previous context, significant progress in the development of the installation belongs to him and his Harvard team.

Lukin himself has repeatedly said that a quantum computer cannot be considered a fully programmable and universal computing platform. The platform can provide simulation of physical processes at the quantum level, but in a limited range of applications. Nevertheless, he was somehow persuaded to become one of the founders of QuEra Computing and set himself the goal of creating systems of hundreds, thousands and hundreds of thousands of qubits.

QuEra Computing’s solution relies on supercooled rubidium atoms embedded in crystal lattice defects. At first, the atoms “hang” in the defects randomly, but with the help of the so-called optical tweezers – laser pulses – the atoms can be arranged in the desired order, which is somewhat reminiscent of programming. Then the computation (simulation) process is started and the system, depending on the initial conditions and the sequence of point impacts by lasers on individual atoms (in fact, this is the execution of the algorithm), comes to a certain state (gives the result of the computation).

Some of these processes cannot be calculated on computers in a reasonable amount of time, or even never at all, but the simulation on qubits gives the result quickly and with a relatively small probability of error. For example, 256 qubits give a combination that exceeds the number of atoms in the solar system. Imagine if there are a thousand or hundreds of thousands of such qubits? Definitely, something interesting and previously unimaginable will turn out, although scientists also do not really understand what it will be.

However, this does not interfere with making money, and prospects can change a lot in our life, if not everything. At least QuEra Computing is backed by the world’s best specialists in this field. Such people can and should be supported in all endeavors.
