Efficient Estimation of Pauli Channels [PDF]
ACM Transactions on Quantum Computing, 2020 Pauli channels are ubiquitous in quantum information, both as a dominant noise source in many computing architectures and as a practical model for analyzing error correction and fault tolerance. Here, we prove several results on efficiently learning Pauli channels and more generally the Pauli projection of a quantum channel.

Dispensing with Channel Estimation… [PDF]
IEEE Vehicular Technology Magazine, 2010 In this article, we investigate the feasibility of noncoherent detection schemes in wireless communication systems as a low-complexity alternative to the family of coherent schemes. The noncoherent schemes require no channel knowledge at the receiver for the detection of the received signal, while the coherent schemes require channel inherently complex

Unitarity Estimation for Quantum Channels
IEEE Transactions on Information Theory, 2023 Estimating the unitarity of an unknown quantum channel $\mathcal{E}$ provides information on how much it is unitary, which is a basic and important problem in quantum device certification and benchmarking. Unitarity estimation can be performed with either coherent or incoherent access, where the former in general leads to better query complexity while ...

The Extended-Window Channel Estimator for Iterative Channel-and-Symbol Estimation
EURASIP Journal on Wireless Communications and Networking, 2005 L'application de l'algorithme de maximisation des attentes (EM) à l'estimation des canaux aboutit à un estimateur itératif de canaux et de symboles (ICSE) bien connu. L'EM-ICSE itère entre un estimateur de symbole basé sur la récursivité avant-arrière (égaliseur BCJR) et un estimateur de canal, et peut fournir des estimations approximatives de canal ...

Optimal channels for channelized quadratic estimators
Journal of the Optical Society of America A, 2016 We present a new method for computing optimized channels for estimation tasks that is feasible for high-dimensional image data. Maximum-likelihood (ML) parameter estimates are challenging to compute from high-dimensional likelihoods. The dimensionality reduction from M measurements to L channels is a critical advantage of channelized quadratic ...

Channel Performance Estimations with Extended Channel Probing
CoRR, 2021 We test the concept of extended channel probing in an Optical Spectrum as a Service scenario in coherent optimized flex-grid long-haul and 10Gbit/s OOK optimized 100-GHz fixed-grid dispersion-managed legacy DWDM networks. An estimation accuracy better than +/- 0.1dB in GSNR implementation margin is obtained for both networks by using flexible coherent ...
