Provided that they can be made really big, quantum computers can offer impressive speedups over their classical counterparts. Such computations can be implemented using only single-site operations on large entangled cluster states (this is known as measurement-based quantum computation). Though continuous-variable cluster states can be generated on an unprecedented scale using current quantum optics technology, a major bottleneck hindering their use is the noise that arises from having limited squeezing resources. In this talk, I will review the basics of measurement-based quantum computation and elaborate on some new protocols for generating and using highly scalable continuous-variable cluster states. Our schemes make more efficient use of available squeezing and possess novel features.
