| Research Abstract |
In order to realize silicon-based quantum computers, we have investigated the mechanisms and suppression of decoherence of electron and nuclear spin qubits, generated and detected highly pure quantum entanglements between phosphorus-donor electron and nuclear spins, developed a multi-state-storage systems known as quantum holographic memories, and explored the possibilities of bismuth donors as quantum memories to connect directly superconducting qubits. While above mentioned topics were listed in the originally proposed plan, we have further developed a way to utilize Si-29 nuclear spins as quantum memories and investigated a variety of spin triplet systems in silicon for application to quantum information processing.
