Ground State Quantum Computation
arXiv:quant-ph/9908035 · doi:10.1103/PhysRevA.63.040302
Abstract
We formulate a novel ground state quantum computation approach that requires no unitary evolution of qubits in time: the qubits are fixed in stationary states of the Hamiltonian. This formulation supplies a completely time-independent approach to realizing quantum computers. We give a concrete suggestion for a ground state quantum computer involving linked quantum dots.
