Quantum simulation of electronic structure Introduction to OpenFermion FQE vs OpenFermion vs Cirq: Quadratic Hamiltonian Evolution Hamiltonian Time Evolution and Expectation Value Computation

InteractionOperator, or DiagonalCoulombHamiltonian to convert to a QubitOperator.

Operators are mapped as follows: a_j^\dagger -> Z0 .. Z{j-1} (X_j - iY_j) / 2 a_j -> Z0 .. Z{j-1} (X_j + iY_j) / 2

Returns
`transformed_operator`	An instance of the QubitOperator class.

Warning
The runtime of this method is exponential in the maximum locality of the original FermionOperator.

Raises
`TypeError`	Operator must be a FermionOperator, DiagonalCoulombHamiltonian, or InteractionOperator.
