Quantum computer based on ion chain control

The use of multiple ion chains in a single ion trap of a quantum information processing (QIP) system is described. Each chain may have an own set of laser beams for implementing and operating quantum gates within that chain, so that each chain may correspond to a single quantum computing register or core. Operations may be performed in parallel on all of these chains as they may be processed independently of one another. To achieve and operate quantum gates between different chains, adjacent chains are merged into a single longer chain, where quantum gates can be performed between any ions in the longer chain. The combined chain can then be separated again by another shuttle event as needed. In order to implement and operate quantum gates between ions that do not occupy adjacent chains, an exchange gate may be used through a series of intervening chains. 描述了在量子信息处理(QIP)系统的单个离子阱中使用多条离子链。每条链可以具有自己的一组激光束，用于在该链内实现和操作量子门，因此每条链可以对应于单个量子计算寄存器或核心。操作可以在所有这些链上并行执行，因为它们可以被彼此独立地处理。为了实现和操作不同链之间的量子门，相邻链被合并为单条较长链，其中可以在该较长链中
