    "abstract": "We propose a parallel quantum computing mode for ensemble quantum computer.\nIn this mode, some qubits can be in pure states while other qubits in mixed\nstates. It enables a single ensemble quantum computer to perform\n$\"$single-instruction-multi-data\" type of parallel computation. In Grover\u0027s\nalgorithm and Shor\u0027s algorithm, parallel quantum computing can provide\nadditional speedup. In addition, it also makes a fuller use of qubit resources\nin an ensemble quantum computer. As a result, some qubits discarded in the\npreparation of an effective pure state in the Schulman-Varizani, and the\nCleve-DiVincenzo algorithms can be re-utilized.",
