The Quantum No-Stretching: A geometrical interpretation of the no-cloning theorem [PDF]
, 2009 We consider the ideal situation in which a space rotation is transferred from a quantum spin j to a quantum spin l different from j. Quantum-information theoretical considerations lead to the conclusion that such operation is possible only for lj.

Characterising a universal cloning machine by maximum-likelihood estimation [PDF]
, 2000 We apply a general method for the estimation of completely positive maps to the 1-to-2 universal covariant cloning machine. The method is based on the maximum-likelihood principle, and makes use of random input states, along with random projective ...

Optimizing completely positive maps using semidefinite programming [PDF]
, 2001 Recently, a lot of attention has been devoted to finding physically realizable operations that realize as closely as possible certain desired transformations between quantum states, e.g., quantum cloning, teleportation, quantum gates, etc. Mathematically,

Stack Overflow in Github: Any Snippets There? [PDF]
IEEE Working Conference on Mining Software Repositories, 2017 When programmers look for how to achieve certain programming tasks, Stack Overflow is a popular destination in search engine results. Over the years, Stack Overflow has accumulated an impressive knowledge base of snippets of code that are amply ...

Incremental Clone Detection and Elimination for Erlang Programs [PDF]
, 2011 A well-known bad code smell in refactoring and software maintenance is the existence of code clones, which are code fragments that are identical or similar to one another. This paper describes an approach to incrementally detecting 'similar' code based on the notion of least-general common abstraction, or anti-unification, as well as a framework for ...

Jupyter Notebooks on GitHub: Characteristics and Code Clones [PDF]
The Art, Science, and Engineering of Programming, 2020 Jupyter notebooks have emerged as a standard tool for data science programming. Programs in Jupiter notebooks are different from typical programs by dividing code into snippets interleaved with text and visualisation and allowing interactive exploration ...

Monogamy of Bell's inequality violations in non-signaling theories
, 2009 We derive monogamy relations (tradeoffs) between strengths of violations of Bell's inequalities from the non-signaling condition. Our result applies to general Bell inequalities with an arbitrary large number of partners, outcomes and measurement ...

Efficient Monitoring of Parametric Context Free Patterns [PDF]
, 2008 Recent developments in runtime verification and monitoring show that parametric regular and temporal logic specifications can be efficiently monitored against large programs.

State estimation from pair of conjugate qudits [PDF]
, 2006 We show that, for $N$ parallel input states, an anti-linear map with respect to a specific basis is essentially a classical operator. We also consider the information contained in phase-conjugate pairs $|\phi > |\phi^*>$, and prove that there is more ...
