Electron on Helium: First Step Toward Reading a Quantum Bit ⚡ экспресс
Original: "Strong coupling of a microwave photon to an electron on helium"
For the first time, scientists achieved resonance between the motion of an electron on superfluid helium and a microwave field.

Electrons floating on superfluid helium are ideal qubits: cold, isolated, noise-free. But measuring a single electron was impossible. Now scientists have coupled its motion to a microwave photon—like sending a rhythm through a taut string. A step toward a scalable quantum computer on helium.
🎯 At 0.1 K, 3000 times colder than room temperature, helium stops boiling and becomes a superfluid film, perfectly isolating electrons.
🎬 In the future, quantum processors might run on a superfluid helium film that cleans itself by oozing through microscopic channels.
g/2\pi = 118\text{ МГц}
Here g is the strength of interaction between the electron’s motion and the photon in the resonator.
