Quantum and Classical Algorithms for Approximate Submodular Function Minimization

no code implementations11 Jul 2019 Yassine Hamoudi, Patrick Rebentrost, Ansis Rosmanis, Miklos Santha

Our classical result improves on the algorithm of [CLSW17] and runs in time $\widetilde{O}(n^{3/2}/\epsilon^2 \cdot \mathrm{EO})$.

Quantum generalizations of the polynomial hierarchy with applications to QMA(2)

1 code implementation28 May 2018 Sevag Gharibian, Miklos Santha, Jamie Sikora, Aarthi Sundaram, Justin Yirka

The polynomial-time hierarchy ($\mathrm{PH}$) has proven to be a powerful tool for providing separations in computational complexity theory (modulo standard conjectures such as $\mathrm{PH}$ does not collapse).
