Sampling equilibrium ensembles of dense polymer mixtures is a paradigmatically hard problem in computational physics, even lattice-based models. Here, we develop formalism based on interacting binary tensors that allows for tackling this using quantum annealing machines. Our approach general properties such as self-avoidance, branching, and looping can all be specified terms quadratic interacti...

Prof. Ching-Ray Chang received his B.S. degree in physics from National Taiwan University (NTU), Taipei, Taiwan, 1979, and Ph.D. the of California, San Diego, 1988. Since 1989, he has been with NTU had chance to serve as executive vice president interim university. worked micromagnetic numerical modeling since 1980. He not only carried out pioneering studies structures but also applied Landau-L...

A summative assessment of quantum computing's progress, based on market readiness and investment levels, its future implications.

uantum computers will utilize nonclassical logic operations to perform numerical calculations that are not feasible on conventional computers. The enhanced capabilities of quantum computers result partly from their expected ability to perform many different calculations simultaneously on a single processor. The Applied Physics Laboratory is developing an optical approach to quantum computing. (

This paper gives a glimpse of basic quantum computing concepts, which is an active area of research in today's world. The discussion starts with difference between a quantum computer and a classical one at the bit level, register level, logic gates level and at circuit level. Then, some of the important quantum phenomena such as quantum entanglement and quantum interference are discussed. After...
