The Kish Key Distribution (KKD) system has been proposed as a classical alternative to quantum key distribution, making use of temperature-matched thermal noise. Previous analyses assume instant propagation of signals along the cable connecting the two users.We describe a new attack that takes an advantage of propagation delays. At the start of each bit period, the noise temperature will then b...

We study the variance of the solution of a periodic randomly perturbed one-dimensional Schrödinger operator after propagation through N periods. It is shown that if the frequency of propagation lies inside the band, then the total variance is proportional to Nσ 2, where σ is the intensity of the white noise. However, if the wave frequency is close to the band edge (where the transfer matrix has...

Capacitive and inductive crosstalk noises are expected to be more serious in advanced technologies. However, capacitive and inductive crosstalk noises in the future have not been concurrently and sufficiently discussed quantitatively, though capacitive crosstalk noise has been intensively studied solely as a primary factor of interconnect delay variation. This paper quantitatively predicts the ...

Noise in quantum operations often negates the advantage of computation. However, most classical simulations computers calculate ideal probability amplitudes by either storing full state vectors or using sophisticated tensor-network contractions. Here we investigate sampling-based simulation methods for noisy circuits. Specifically, characterize costs two major schemes, stabilizer-state sampling...

Noise eeects such as power supply and crosstalk noise can signiicantly impact the performance of deep submicron designs. Existing timing analysis tecniques cannot capture the eeects of noise on the signal/cell delays. This is because these delay eeects are highly input pattern dependent. Therefore, the predicted circuit performance might not reeect the worst-case circuit delay. In this paper, w...

Wind turbine acoustical noise is a relevant element to be considered and studied because of the growing interest in renewable energies. The environmental impact of these structures in the surrounding areas is deeply investigated, especially on the acoustical and the landscape point of view. This paper is mainly devoted to the integration between analytical, experimental and software analysis on...

The high noise levels associated with full-scale military aircraft result in nonlinear propagation, which results in acoustic shock formation and can alter noise perception. This propagation has been modeled for other aircraft but previous studies have been limited in scope, showing results for only select engine conditions and angles. Recent data measured near an F-35B allow for a more complet...

In this work, with combined belief propagation (BP), mean field (MF) and expectation propagation (EP), an iterative receiver is designed for joint phase noise (PN) estimation, equalization and decoding in a coded communication system. The presence of the PN results in a nonlinear observation model. Conventionally, the nonlinear model is directly linearized by using the first-order Taylor approx...
