FAMU-FSU College of Engineering designs qubit with floating electrons above chip
Researchers at FAMU-FSU College of Engineering have designed a qubit architecture that uses electrons floating above a chip rather than confined in a semiconductor material. The design was reported by Quantum Zeitgeist on 21 August 2026. No experimental demonstration was described in the report.

The floating-electron design could lead to a working qubit prototype with longer coherence times than comparable silicon spin qubits within two years.
Electrons suspended above a chip surface avoid charge noise from semiconductor interfaces, a leading decoherence source. Electron-on-helium systems have already demonstrated single-electron trapping, and existing cryogenic and nanofabrication techniques could be adapted to build a test device. The main gate is integrating trap electrodes with a reliable electron loading scheme at millikelvin temperatures.
