Measurement-Based Quantum Computation (MBQC) is a model of quantum computation driven by measurements instead of unitary gates. In 2D it is capable of supporting universal quantum computations. Interestingly, while all measurements are local, the computational output involves non local observables. We will use the simpler case of 1D MBQC to illustrate how these features can be captured by ideas from gauge theory and extended TQFT. We will also explain MBQC from the perspective of the extended Hilbert space construction in gauge theories, in which the entanglement edge modes play the role of the logical qubit.
