Microwave amplification with nanomechanical resonators

Use of nanomechanical resonators has the potential to offer microwave amplification with the minimum possible added noise, namely that due to quantum fluctuations. Noise-free amplification of weak radio signals In order to compensate for energy losses, the radio signals used in telecommunications an...
