摘要:A new generation of application specific quantum computers has

shown great promise in providing this quantum leap. One is

already commercially available, and now undergoing trials at

Google and NASA. This talk will discuss three novel designs

being investigated at SUT, with experiments planned at

Swinburne and elsewhere. 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.
