Quantum Computing Without Wavefunctions: Time-Dependent Density Functional Theory for Universal Quantum Computation
We prove that the theorems of TDDFT can be extended to a class of qubit Hamiltonians that are universal for quantum computation. The theorems of TDDFT applied to universal Hamiltonians imply that single-qubit expectation values can be used as the basic variables in quantum computation and informatio...
