Classes

class AcquaintanceOperation: Represents an a acquaintance opportunity between a particular set of logical indices on a particular set of physical qubits.

class AcquaintanceOpportunityGate: Represents an acquaintance opportunity.

class BipartiteGraphType: Create a collection of name/value pairs.

class BipartiteSwapNetworkGate: A swap network that acquaints qubits in one half with qubits in the other.

class CircularShiftGate: Performs a cyclical permutation of the qubits to the left by a specified amount.

class GreedyExecutionStrategy: A greedy execution strategy.

class LinearPermutationGate: A permutation gate that decomposes a given permutation using a linear sorting network.

class PermutationGate: A permutation gate indicates a change in the mapping from qubits to logical indices.
