| Tytuł | Changing the circuit-depth complexity of measurement-based quantum computation with hypergraph states |
| Szczegóły | While the circuit model of quantum computation defines its logical depth or “computational time” in terms of temporal gate sequences, the measurement-based model could allow totally different temporal ordering and parallelization of logical gates. By developing techniques to analyze Pauli measurements on multiqubit hypergraph states generated by the controlled-controlled-Z (ccz) gates, we introduce a deterministic scheme of universal measurement-based computation. In contrast to the cluster-state scheme where the Clifford gates are parallelizable, our scheme enjoys massive parallelization of ccz and swap gates, so that the computational depth grows with the number of global applications of Hadamard gates, or, in other words, with the number of changing computational bases. A logarithmic-depth implementation of an N-times controlled-Z gate illustrates a trade-off between space and time complexity. ______________________________________________ Zoom meeting details Topic: Quantum Information and Quantum Computing Working Group Time: July 02, 2020, 04:00 PM Warsaw Meeting ID: 922 2710 3826 If you encounter any problems with connecting to the Zoom meeting, please email filip.b.maciejewski@gmail.com directly. |
