Idea

What has come to be known as measurement based quantum computation is a scheme for quantum computation in which quantum gates are implemented by partial quantum measurement on entangle states (Bell states).

Due to wavefunction collapse upon quantum measurement, such processes are not reversible on the total quantum state space — conversely, each such measurement-based gate operation “uses up the entanglement-resource” in order to implement (reversible) quantum gates on a computational subspace. Therefore one also speaks of “one-way quantum computation” [Raussendorf &Briegel (2001)].
