EeroQ Advances Its Electron on Helium (eHe) Qubit Technology - Quantum Computing Report

EeroQ has been developing a unique modality that involves using electrons bound to the surface of superfluid helium as the qubits. This approach is less mature than other, more common modalities, but it might be able provide significant advantages in the future including long coherence times, small qubit size, fast gates, and CMOS compatibility once the technology is developed further. The company has just published a technical paper in Nature Physics describing a successful demonstration of Strong coupling of a microwave photon to an electron on helium that provides a mechanism to readout the state of the qubit. The approach uses [...]
