最近，理学院物理系本科生王亚鹏以第一作者的身份在MDPI旗下的国际学术期刊Entropy（IF：2.494）上发表题为“Digital quantum simulation of nonadiabatic geometric gates via shortcuts to adiabaticity”的学术论文。王亚鹏为2017级物理系应用物理专业本科生。2019年底进入上海大学量子人工智能科学技术中...
By precisely measuring the entropy of a cerium copper gold alloy with baffling electronic properties cooled to nearly absolute zero, physicists in Germany and the United States have gleaned new eviden...
We present an analytical study on the resilience of topological order after a quantum quench. The system is initially prepared in the ground state of the toric-code model, and then quenched by switchi...
Postprocessing for quantum random-number generators: Entropy evaluation and randomness extraction
Postprocessing quantum random-number generator Entropy evaluation randomness extraction
2016/1/23
Quantum random-number generators (QRNGs) can offer a means to generate information-theoretically provable random numbers, in principle. In practice, unfortunately, the quantum randomness is inevitably...
A comment on the relation between diffraction and entropy
relation between diffraction and entropy Mathematical Physics
2012/5/24
Diffraction methods are used to detect atomic order in solids. While uniquely ergodic systems with pure point diffraction have zero entropy, the relation between diffraction and entropy is not as stra...
Explicit Bounds for Entropy Concentration under Linear Constraints
maximum entropy concentration bounds linear constraints tolerances
2011/8/19
Abstract: Consider the construction of an object composed of $m$ parts by distributing $n$ units to those parts. For example, say we are assigning $n$ balls to $m$ boxes. Each assignment results in a ...
The Smooth Entropy Formalism on von Neumann Algebras
Smooth Entropy Formalism von Neumann Algebras Quantum Physics
2011/10/9
Abstract: We discuss quantum information theoretical concepts on von Neumann algebras and lift the smooth entropy formalism to the most general quantum setting. For the smooth min- and max-entropies w...
Enhancing the understanding of entropy through computation
Enhancing entropy through computation computational algorithms distinguishable particles
2011/8/11
Abstract: We devise a hierarchy of computational algorithms to enumerate the microstates of a system comprising N independent, distinguishable particles. An important challenge is to cope with integer...
Starting from the universal entropy bounds suggested by Bekenstein and Susskind and applying them to the black-body radiation situation, we get a cut-off of space x ≥ lP with ≥ 0.1. We go further ...
On some special cases of the Entropy Photon-Number Inequality
the Entropy Photon-Number Inequality Quantum Physics Information Theory
2011/10/8
Abstract: We show that the Entropy Photon-Number Inequality (EPnI) holds where one of the input states is the vacuum state and for several candidates of the other input state that includes the cases w...
Infinitely many constrained inequalities for the von Neumann entropy
von Neumann entropy Quantum Physics
2011/9/29
Abstract: We exhibit infinitely many new, constrained inequalities for the von Neumann entropy, and show that they are independent of each other and the known inequalities obeyed by the von Neumann en...

Corrected entropy-area relation New agegraphic dark energy Hoˇrava-Lifshitz cosmology
2011/9/1
We investigate the new agegraphic dark energy (NADE) model with power-law corrected entropy in the framework of Hoˇrava-Lifshitz cosmology. For a non-flat universe containing the interacting power-law...

A Characterization of Entropy in Terms of Information Loss
Shannon entropy Tsallis entropy information theory measure-preserving function
2011/7/27
Abstract: There are numerous characterizations of Shannon entropy and Tsallis entropy as measures of information obeying certain properties. Using work by Faddeev and Furuichi, we derive a very simple...
Entanglement Entropy of Two Black Holes and Entanglement Entropic Force
Entanglement Entropy Two Black Holes Entanglement Entropic Force
2010/12/23
We study the entanglement entropy, $S_C$, of a massless free scalar field on the outside region $C$ of two black holes $A$ and $B$ whose radii are $R_1$ and $R_2$ and how it depends on the distance, ...
