A new generation of application specific quantum computers has shown great promise in providing this quantum leap. One is already commercially available, and now undergong trials at Google and NASA. This talk will discuss three novel designs being unbestigated at SUT, with experiments planned at Swinburne and lese where. The largest quantum computer in the world is the Stanford/Tokyo Ising machine. But can it really outperform classical computers at NP-hard optimization? We discuss the physics of this novel device, and how it is theoretically modeled. An alternative hardware model is the XY machine, which uses a different type of photonic interaction, and with experiments at the Weizmann Institute in Israel. Preliminary theory at SUt of a novel parametric XY machine will be given. We have also developed both a quantum simulation of a boson sampling quantum computer, and analytic results. This gives signatures that verify the computational output. Finally, we propose that the emulation of the quantum decay of a relativistic scalar field from a metastable state can be simulated using an ultra-cold spinor Bose gas. This will demonstrate that an exponentially complex, high energy theoretical model can be solved on a table-top quantum computer. Movies of our simulations of the planned SUT laboratory demonstration will be given.
