避免某些时间复杂度问题的新的基于噪声的逻辑表示

New noise-based logic representations to avoid some problems with time complexity

H. Wen, L. B. Kish, A. Klappenecker, F. Peper

摘要:

基于瞬时噪声的逻辑可以避免时间平均,这意味着在超越摩尔定律的芯片中低功耗并行操作的巨大潜力。然而,在随机电报波表示中,全域(均匀叠加)将以高概率为零(非零以指数低概率),因此对全域的操作将需要指数时间复杂度。为了解决这个问题,我们修改了L和H状态的信号幅度,并实现了与旧情况相比的指数加速。另一个改进涉及单个产品(超空间)状态的识别。我们介绍了一个时移噪声为基础的逻辑,这是通过移动每个参考信号与一个小的时间延迟。与前一种情况相比,这种修改意味着单个超空间向量识别的指数加速,并且它需要与量子计算相同的O(N)复杂度。

英文摘要:

Instantaneous noise-based logic can avoid time-averaging, which implies significant potential for low-power parallel operations in beyond-Moore-law-chips. However, the universe (uniform superposition) will be zero with high probability (non-zero with exponentially low probability) in the random-telegraph-wave representation thus the operations with the universe would require exponential time-complexity. To fix this deficiency, we modify the amplitudes of the signals of the L and H states and achieve an exponential speedup compared to the old situation. Another improvement concerns the identification of a single product (hyperspace) state. We introduce a time shifted noise-based logic, which is constructed by shifting each reference signal with a small time delay. This modification implies an exponential speedup of single hyperspace vector identification compared to the former case and it requires the same, O(N) complexity as in quantum computing.
