In the first area, we demonstrate a polynomial-time (classical) approximation algorithm for dense instances of the canonical QMA-complete quantum constraint satisfaction problem, the local Hamiltonian problem. In the opposite direction, we next introduce a quantum generalization of the polynomial-time hierarchy, and define problems which we prove are not only complete for the second level of this hierarchy, but are in fact hard to approximate. In the second area, we study variants of the interesting and stubbornly open question of whether a quantum proof system with multiple unentangled quantum provers is equal in expressive power to a proof system with a single quantum prover. Our results concern classes such as BellQMA(poly), and include a novel proof of perfect parallel repetition for SepQMA(m) based on cone programming duality. In the third area, we study non-classical quantum correlations beyond entanglement, often dubbed "non-classicality". Among our results are two novel schemes for quantifying non-classicality: The first proposes the new paradigm of exploiting local unitary operations to study non-classical correlations, and the second introduces a protocol through which non-classical correlations in a starting system can be "activated" into distillable entanglement with an ancilla system. An introduction to all required linear algebra and quantum mechanics is included.}}, author = {{Gharibian, Sevag}}, pages = {{240}}, title = {{{Approximation, Proof Systems, and Correlations in a Quantum World}}}, year = {{2013}}, } @article{8173, abstract = {{We study three variants of multi-prover quantum Merlin-Arthur proof systems. We first show that the class of problems that can be efficiently verified using polynomially many quantum proofs, each of logarithmic-size, is exactly MQA (also known as QCMA), the class of problems which can be efficiently verified via a classical proof and a quantum verifier. We then study the class BellQMA(poly), characterized by a verifier who first applies unentangled, nonadaptive measurements to each of the polynomially many proofs, followed by an arbitrary but efficient quantum verification circuit on the resulting measurement outcomes. We show that if the number of outcomes per nonadaptive measurement is a polynomially-bounded function, then the expressive power of the proof system is exactly QMA. Finally, we study a class equivalent to QMA(m), denoted SepQMA(m), where the verifier's measurement operator corresponding to outcome "accept" is a fully separable operator across the m quantum proofs. Using cone programming duality, we give an alternate proof of a result of Harrow and Montanaro [FOCS, pp. 633--642 (2010)] that shows a perfect parallel repetition theorem for SepQMA(m) for any m.}}, author = {{Gharibian, Sevag and Sikora, Jamie and Upadhyay, Sarvagya}}, journal = {{Quantum Information & Computation}}, number = {{1-2}}, pages = {{135--157}}, title = {{{QMA variants with polynomially many provers}}}, volume = {{13}}, year = {{2013}}, } @phdthesis{42132, author = {{Gerkens, Stefan}}, isbn = {{978-3-8440-2421-0}}, pages = {{168}}, title = {{{In-situ Strukturcharakterisierung von CNT in polymerbasierten Nanokompositen Methodenentwicklung und Anwendung}}}, volume = {{1}}, year = {{2013}}, } @techreport{42718, author = {{Fuchs, Christian}}, issn = {{2270-7467}}, title = {{{Privacy and Security in Europe.
