The Quantum Travelling Salesman

Quantum computing has been touted as a game-changing technology, but what will its true impact be? QxBranch has developed a method for solving the Travelling Salesman Problem – a flagship challenge in optimization – using the D-Wave Two® quantum computer. Using a quantum computing approach has the potential to revolutionize the many applications of this difficult problem.

Foreign Exchange Pairs Portfolio Optimizaton

How will quantum computing affect your business? QxBranch presents the first in a series of white papers showing current, commercially available quantum computers solving real world problems. We take a common investment problem – portfolio optimization, demonstrate how to run the problem on a D-Wave Two® quantum computer and show how the D-Wave Two® successfully handles a complicating feature that is challenging for classical computers to solve. We link the quantum computing capabilities of today to a transformative, quantum-powered future.
