Lecture 29: Quantum Logic Operations in Measurement Based Quantum Computation, and more

The state teleportation example in measurement based quantum computation is extended to logic gate teleportation. Universality of measurement based quantum computation is demonstrated with one-qubit J(theta) and two-qubit CZ gates. Hadamard gate is needed for initial state preparation. Required spatial resources are higher by a constant factor compared to logic circuit based quantum computing, but temporal resources reduce due to parallelisation. Photonic implementation scheme is described, and demonstration of Grover’s algorithm for selecting 1 out of 4 items (in 2005) is explained.
