Unbiased sources of true randomness are crucial for the next generation of encryption applications and stochastic computing in various fields, yet achieving such randomness without bias has remained technically challenging. This study introduces an innovative hardware approach, utilizing the intrinsic balance of phase noise in a spintronic nano-oscillator synchronized at twice its natural frequency to overcome bias in random bitstream generation at room temperature. The method generates truly random bitstreams with efficiency and reliability that is expected to significantly impact cybersecurity, advanced computing, and more.
