Quantum Simulation

Quantum computation is a promising emerging technology which, compared to classical computation, allows for substantial speed-ups e.g. for integer factorization or database search. However, since physical realizations of quantum computers are in their infancy, a significant amount of research in this domain still relies on simulations of quantum computations on classical machines. This causes a significant complexity which current state-of-the-art simulators tackle by applying massive hardware power. Here, we present the implementation of an alternative quantum simulator which works differently to the state-of-the-art and is capable of simulating quantum computations with more qubits than before, and in significantly less run-time.

The implementation (including a README with instructions as well as corresponding test-files) can be downloaded by clicking on this link (65.3 KB).

Details of the approach are summarized in the paper entitled "Advanced Simulation of Quantum Computations".
