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.^[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.^[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 probabilityA $2.5\mu \mathrm{s}$ pulse gives $P=1/2$, while a $5.0\mu \mathrm{s}$ 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.
