Quantum Fourier Transform in a Decoherence-Free Subspace [article]

Jian-wu Wu, Chun-wen Li, Re-bing Wu
2004 arXiv   pre-print
Quantum Fourier transform is of primary importance in many quantum algorithms. In order to eliminate the destructive effects of decoherence induced by couplings between the quantum system and its environment, we propose a robust scheme for quantum Fourier transform over the intrinsic decoherence-free subspaces. The scheme is then applied to the circuit design of quantum Fourier transform over quantum networks under collective decoherence. The encoding efficiency and possible improvements are also discussed.

Total colorings of planar graphs without adjacent triangles

Xiang-Yong Sun, Jian-Liang Wu, Yu-Wen Wu, Jian-Feng Hou
2009 Discrete Mathematics  
Let G be a planar graph without adjacent 3-cycles, that is, two cycles of length 3 are not incident with a common edge. In this paper, it is proved that the total coloring conjecture is true for G; moreover, if ∆(G) ≥ 9, then the total chromatic number χ (G) of G is ∆(G) + 1. Some other related results are obtained, too.

However, kernel competitive learning (KCL) is not scalable for large scale data processing, because (1) it has to calculate and store the full kernel matrix that is too large to be calculated and kept in the memory and (2) it cannot be computed in parallel. In this paper we develop a framework of approximate kernel competitive learning for processing large scale dataset. The proposed framework consists of two parts. First, it derives an approximate kernel competitive learning (AKCL), which learns kernel competitive learning in a subspace via sampling. We provide solid theoretical analysis on why the proposed approximation modelling would work for kernel competitive learning, and furthermore, we show that the computational complexity of AKCL is largely reduced. Second, we propose a pseudo-parallelled approximate kernel competitive learning (PAKCL) based on a set-based kernel competitive learning strategy, which overcomes the obstacle of using parallel programming in kernel competitive learning and significantly accelerates the approximate kernel competitive learning for large scale clustering. The empirical evaluation on publicly available datasets shows that the proposed AKCL and PAKCL can perform comparably as KCL, with a large reduction on computational cost. Also, the proposed methods achieve more effective clustering performance in terms of clustering precision against related approximate clustering approaches.

Irregular changes in Hα emission line of V423 Aur observed by LAMOST Medium-Resolution Spectrographs [article]

2019 arXiv   pre-print
We obtained 7 spectra of the Be star V423 Aur on Dec. 5th, 2017 using the LAMOST Medium-Resolution Spectrograph with exposures from 600 to 1200 seconds. These spectra show the irregular Hα emission line profile variations (LPVs). In the seven spectra, from the 4th to 7th, the left part of Hα profile even show excess. However, no variation can be seen from the follow-up observation of photometry by 1.26-m telescope and High-Resolution spectra by 2.16-m telescope. According to the High-Resolution

In this paper we show a new way to generate entanglement via two identical three-level atoms splitting in the magnetic field interacting with the cavity field. By the system we investigate, We can acquire the EPR state, multi-dimensional entangled states etc. which are more stable than usual realization by high-energy-level Rydberg atoms and we can realize the local exchange operator too. We also achieve the goal of maintaining long- time entanglement between atoms. At last, by using the

(Pseudo) Preimage Attack on Round-Reduced Grøstl Hash Function and Others [chapter]

Shuang Wu, Dengguo Feng, Wenling Wu, Jian Guo, Le Dong, Jian Zou
2012 Lecture Notes in Computer Science  
The Grøstl hash function is one of the 5 final round candidates of the SHA-3 competition hosted by NIST. In this paper, we study the preimage resistance of the Grøstl hash function. We propose pseudo preimage attacks on Grøstl hash function for both 256-bit and 512-bit versions, i.e., we need to choose the initial value in order to invert the hash function. Pseudo preimage attack on 5(out of 10)-round Grøstl-256 has a complexity of (2 244.85 , 2 230.13 ) (in time and memory) and pseudo preimage

To the best of our knowledge, our attacks are the first (pseudo) preimage attacks on round-reduced Grøstl hash function, including its compression function and output transformation. These results are obtained by a variant of meet-in-the-middle preimage attack framework by Aoki and Sasaki. We also improve the time complexities of the preimage attacks against 5-round Whirlpool and 7-round AES hashes by Sasaki in FSE 2011.
