  7. Abstract:
  8. Quantum computation is an unconventional way to compute employing quantum Physics. In this way of computation, quantum superposition and quantum entanglement have crucial roles to surpass common ways of computation. There is a special method for quantum computing which is known as “measurementbased quantum computation” (MBQC). In this method, sequential single-site measuring a highly-entangled state is used to perform computation. All of the existing MBQC models can be described in the “correlation space,” a virtual space corresponding to the physical space, of tensor network states. In this thesis, we introduce a recipe for designing such MBQC models. We elaborate our designing for correlation-space MBQC through an example model defined on honeycomb lattice. In addition in this thesis, we present a fairly general method for “blind quantum computation” (BQC) on the correlation-space MBQC models. A BQC protocol is a computational protocol in which a client can perform a quantum computation on a quantum server without revealing the computation and the result to the server. Our method can also be implemented on circuit-based quantum computation models
