The NV qubit

You will be able to

  • Read an ODMR spectrum and relate line splitting to magnetic field
  • Distinguish Rabi, Ramsey, and echo experiments
  • Explain what T₂* and T₂ measure

Set T₂* to 2 µs. Run Ramsey and Echo with the same free time of 5 µs. Why does one keep its coherence and the other lose it?

f = np.linspace(2780, 2960, 7)
print(nv.odmr_spectrum(f, np.array([0, 0, 2.0]), hyperfine=False).round(4))

t = np.linspace(0, 1, 5)
print(nv.rabi(t, 2.0).round(3))
