Abstract: | Provided they can be made on a large scale with low levels of noise, quantum computers offer impressive speedups over their classical counterparts. Such computations can be implemented using only single-site operations on specially prepared resource states, known as cluster states. Recent theoretical and experimental breakthroughs have shown the potential for large-scale generation of continuous-variable cluster states in compact optical setups. An important property of these states is that they possess a multi-layered graph structure. In this talk, I will begin with the basics of measurement-based quantum computation. Next I will describe recent extensions that apply to multi-layered cluster states, allowing for more compact and flexible computations. A major bottleneck hindering the use of continuous-variable cluster states is the noise that arises from having limited squeezing resources. I will discuss how to treat this noise as an effective amplitude-dampi ng channel in the special case of implementing linear optics gates. | |
