<Fedor Jelezko> works on solid-state <quantum optics> and spin control in <diamond>. His Ulm University CV identifies him in full and lists the exact 2004 nuclear-spin paper whose first-author byline is F. Jelezko, verifying the connection between the full name and the abbreviated record.<Fedor Jelezko at Ulm University>[Official CV, page1 expertise and page2 selected publications, DOI10.1103/PhysRevLett.93.130501]{ref}
That experiment addressed an <electron spin> coupled to a single <Carbon-13> <nuclear spin> at a <nitrogen-vacancy center>. A <laser> initialized and read out the electron-spin-dependent signal, while <microwave> and <radio frequency> pulses manipulated the coupled levels. Nuclear-state changes were detected through the electron spin. The team observed nuclear <Rabi oscillations> and demonstrated a conditional two-qubit gate, providing a physical test of coherent control of an individually addressed spin system.<Observation of coherent oscillation of a single nuclear spin and realization of a two-qubit conditional quantum gate by F. Jelezko and others>[Abstract; pages2–3 and Figure2, coupled spins and optical/microwave/radio-frequency pulse sequence]{ref}
For an original ideal pulse example, let a selected transition have resonant <Rabi frequency> $f_R=100\,\mathrm{kHz}$ and start entirely in one level. The two-level model gives transition probability
$$
P(t)=\sin^2(\pi f_Rt).
$$
A $2.5\,\mathrm{\mu s}$ pulse gives $P=1/2$, while a $5.0\,\mathrm{\mu s}$ pulse gives $P=1$. Scanning the pulse duration reveals an oscillation rather than a single population change. These are chosen ideal values; detuning, relaxation and readout noise limit a real measurement.
