Quantum computing company EeroQ recently published a significant paper in Physical Review X, announcing the first successful control and detection of individual electrons trapped in superfluid helium at temperatures above 1 Kelvin. This milestone achievement in quantum computing, realized through on-chip superconducting microwave circuits compatible with existing quantum hardware, injects new vitality into the development of quantum computing technology.

Traditional quantum computers require operation at ultra-low temperatures near 10 millikelvin, with heat dissipation challenges severely limiting scalability. EeroQ's research demonstrates that individual electrons can be trapped and controlled at temperatures over 100 times higher, opening possibilities for building larger-scale, more practical quantum processors. The results also confirm the superiority of electrons on helium as qubits, with their exceptionally pure and long-lived characteristics, while reducing the need for extreme cooling.

EeroQ co-founder and Chief Scientific Officer Johannes Pollanen stated: "This breakthrough confirms that helium electron qubits can be manipulated and read out at higher temperatures than previously thought possible, reducing a key barrier to scalable quantum computing. Publication in Physical Review X underscores the scientific rigor and industry significance of this progress." Founded in 2017, EeroQ has been dedicated to integrating expertise in physics, engineering, and nanofabrication, using the innovative method of suspending electrons on superfluid helium combined with standard superconducting circuits to build powerful and practical quantum computers.
