Entanglement in quantum spin chains

Vladimir Korepin, Professor, C. N. Yang Institute for Theoretical Physics, Stony Brook University of Sciences 02 August 2018, 15:00-16:00 SkolTech, TPOC-4, Nobel str. 2, Blue Building, 4th floor, Room 407   ABSTRACT. Spin chains are models of realistic quantum devices. They can be realized in optical lattices and appear in un-isotropic crystalline structures in solid state. History of quantum entanglement and spin chains will be explained. The entanglement measures the level of quantum fluctuations. Different spin chains will be reviewed. The chains with highest level of fluctuations will be singled out. Short BIO. Vladimir Korepin is a theoretical and mathematical physicist. He did his undergraduate in Leningrad State University on Mathematical Physics,[…]

Unusual properties of quantum walks

Alexander Rivosh, Researcher, the Center for Quantum Computer Science, University of Latvia 24 July 2018, 15:00-16:30 SkolTech, TPOC-4, Nobel str. 1, Red Building, 3rd floor, Room 351   ABSTRACT. Quantum walks proved to be a useful tool for the design of quantum algorithms. Local search, element distinctness, NAND formula evaluation – that is only a few examples for problems where quantum walk based algorithms exist. We consider quantum walk as an algorithmic tool to perform a search on different graphs. We have to take into account an existence of the whole class of exceptional configurations when we use a quantum walk for search applications. Quantum walk based search algorithms fail to[…]

Quantum Crash Course at Rusky Island (University 2035)

Modern Quantum Computing: enhanced optimization, simulation and machine learning Course Location: Rusky Island – University 20.35 Course Dates: 17-19 July 2018. Teaching Team Jacob Biamonte (lead) Tim Tlyachev Vito Leli Course Content Visionary Lecture. Jacob Biamonte outlines the last 20 years of quantum mechanics, the second quantum revolution and notes that while progress was made we are far from tackling some foundational questions.  Despite this lack of understanding, this actually does not impede the use of quantum mechanics as a computational resource.  18 July 2018, 21:00-23:00, building A. Lecture 1. Introduction to the idea of using the low-energy state of a physical system as a computational resource.  Methods to program and embed problems[…]
