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”. The method has been awarded with a Google Faculty Research Award and has been integrated into IBM’s SDK Qiskit.
