Quantum Algorithms for Matching and Network Flows
Andris Ambainis, Robert Spalek
We present quantum algorithms for the following graph problems: finding a maximal bipartite matching in time O(n sqrt{m+n} log n), finding a maximal non-bipartite matching in time…
Entanglement in Interactive Proof Systems with Binary Answers
Stephanie Wehner
If two classical provers share an entangled state, the resulting interactive proof system is significantly weakened [quant-ph/0404076]. We show that for the case where the verifier…
Lower Bounds on Matrix Rigidity via a Quantum Argument
Ronald de Wolf
The rigidity of a matrix measures how many of its entries need to be changed in order to reduce its rank to some value. Good lower bounds on the rigidity of an explicit matrix woul…
Implications of Superstrong Nonlocality for Cryptography
Harry Buhrman, Matthias Christandl, Falk Unger +2
Non-local boxes are hypothetical ``machines'' that give rise to superstrong non-local correlations, leading to a stronger violation of Bell/CHSH inequalities than is possible withi…
The quantum adversary method and classical formula size lower bounds
Sophie Laplante, Troy Lee, Mario Szegedy
We introduce two new complexity measures for Boolean functions, or more generally for functions of the form f:S->T. We call these measures sumPI and maxPI. The quantity sumPI has b…
Quantum Anonymous Transmissions
Matthias Christandl, Stephanie Wehner
We consider the problem of hiding sender and receiver of classical and quantum bits (qubits), even if all physical transmissions can be monitored. We present a quantum protocol for…
