Topic: A review of simulation techniques of quantum computing

Presentation

Abstract:

One of challenges which current quantum computing simulation techniques try to tackle with is the exponential complexity dictated by the algebraic theory describing quantum computations. This talk will present a variety of simulation techniques starting from a straightforward array-based representation that requires massive hardware power, via graph-based approaches that tries to leverage redundancies in quantum states and operations, ending with solutions based on decision diagrams. The decision diagrams approach [1, 2] exploits redundancies in the respective quantum state and operation descriptions and therefore it is capable of (1) simulating quantum computations for more qubits than other approaches, (2) in significantly less run-time, and (3) on a regular desktop machine.
