EeroQ is a quantum hardware startup founded in 2017 that has recently moved its headquarters to Chicago. They are basing their qubits on a relatively unique technology called electrons-on-helium that was developed by scientists at Michigan State and Princeton University. Their belief is that the electrons-on-helium approach is superior to other qubit approaches because their qubits have longer coherence time, high speed, better connectivity, very high density, and compatibility with semiconductor CMOS processing. This could lead to a much better potential to scale with the ability to fit millions of electrons on one chip.

This funding round was led by B Capital’s Ascent Fund, with additional participation from V Capital, Alumni Ventures, Unbound Ventures, Calibrate Ventures and Red Cedar Ventures. EeroQ is still in the very early stages of its development and working on optimizing the basic operations for only a small number of qubits. But their belief is that once they have optimized the operation, they will be able to scale up the number of qubits very quickly and catch up or surpass the other hardware players who have been working on their technologies for some time. The electrons-on-helium technology has had very few researchers working on it and EeroQ has indicated they have on board several of the leading researchers for this technology as well as rights to many of the patents and other intellectual property for this technology. This would make it hard for others to copy their approach.

Still, a single chip, no matter how good it is, does not make for a complete quantum computer. A full stack will require sophisticated control electronics, firmware, ECC algorithms, SDKs, algorithm libraries, hybrid classical/quantum integration, etc. to be truly useful for an end user. But those other elements can all be obtained via partnerships, acquisitions, or other means. But for now, EeroQ is concentrating its efforts on the basic qubit technology where it could potentially create their greatest advantage and they will work on the other stuff at a later time.
