Nonequilibrium information thermodynamics determines the minimum energy dissipation to reliably erase memory under time-symmetric control protocols. We demonstrate that its bounds are tight and so show that the costs overwhelm those implied by Landauer’s energy bound on information erasure. Moreover, in the limit of perfect computation, the costs diverge. The conclusion is that time-asymmetric protocols should be developed for efficient, accurate thermodynamic computing. And, that Landauer’s Stack—the full suite of theoretically-predicted thermodynamic costs—is ready for experimental test and calibration.

完善Landauer的堆栈:擦除信息时平衡错误和耗散
非平衡信息热力学确定了最小能量耗散,以在时间对称控制协议下可靠地擦除存储器。我们证明了它的范围是紧密的,因此表明其成本远远超过了Landauer在信息擦除方面的精力所隐含的成本。而且,在完美计算的极限中,成本是不同的。结论是,应开发时间非对称协议以进行高效,准确的热力学计算。而且,Landauer的堆栈-一整套理论上预测的热力学成本-已准备好进行实验测试和校准。
