Fundamental Studies of ESR and Optical Bulk Quantum Computing
Abstract
Solution NMR quantum computers are fundamentally limited to small numbers of qubits because energy differences are small compared to kT, and the logic gates that can be created are extremely slow (ca. 100 ms) (see W. S. Warren, Science 277, 1688-1689 (1997)). We proposed to explore the technological and architecture issues associated with two other classes of bulk quantum computing systems: ESR and optical impurity molecules in a dilute lattice. In the ESR case, we synthesized specific molecules that were capable in principle of producing single logic gates. We also dramatically advanced the technology for manufacturing phase coherent femtosecond laser pulse sequences, a critical component of any architecture which could achieve meaningful speedup. Finally, we explored the theoretical issues associated with specific classes of decoherence.
