Sentences with phrase «qubit coherence time»

The 29Si isotope is present at 4.67 percent in natural silicon and is the only stable isotope of silicon that carries a nuclear spin limiting the qubit coherence time.

Not exact matches

In diamond at room temperature, Maurer et al. (p. 1283) show that a spin - based qubit system comprised of an isotopic impurity (13C) in the vicinity of a color defect (a nitrogen - vacancy center) could be manipulated to have a coherence time exceeding one second.

These qubits, taken individually, have demonstrated world - record coherence times.

Since 2012, when the first qubits that relied on electron spins were reported, the introduction of isotopically purified 28Si has led to significant enhancement of the spin coherence time.
