Mimicking time evolution within a quantum ground state: Ground-state quantum computation, cloning, and teleportation
Ari Mizel · Physical Review A · 2004
Ground-state quantum computers mimic quantum-mechanical time evolution within the amplitudes of a time-independent quantum state. We explore the principles that constrain this mimicking. A no-cloning argument is found to impose strong restrictions. It is shown, however, that there is flexibility that can be exploited using quantum teleportation methods to improve ground-state quantum computer design.
