Summary:Embodiments of the microwave amplification system are described. In an embodiment, a microwave amplification system includes a microwave amplifier that contains a paramagnetic material with an impurity. The impurity has a plurality of nuclear spin and electron spin-based energy levels. The system includes an input to receive a pumping signal which is transmitted to the microwave amplifier to cause a population inversion in the impurity and excite it to one of the nuclear spin and electron spin-based energy levels. The system further includes another input to receive an input signal to be amplified by the microwave amplifier, the input signal having a lower power than the pumping signal. Once transmitted to the microwave amplifier, the input signal is amplified by the excited state of the impurity in the microwave amplifier thereby generating an amplified signal.
