论文摘要
我们描述了被困原子量子处理器中每个原子的多个量子位的编码以及在参与者量子台上同时和原子间门的方法，而不会干扰同一原子中存储的观众量子。我们还介绍了选择性状态准备和测量单个Qubit的技术，这些量子位使其他量子位中编码的信息完好无损，这是量子量子误差校正所需的功能。原子处理器中已经存在多数Qubit处理所需的其他内部状态，这表明与此量子数增加相关的资源成本在短期到中期可能是一个很好的便宜货。
We describe the encoding of multiple qubits per atom in trapped atom quantum processors and methods for performing both intra- and inter-atomic gates on participant qubits without disturbing the spectator qubits stored in the same atoms. We also introduce techniques for selective state preparation and measurement of individual qubits that leave the information encoded in the other qubits intact, a capability required for qubit quantum error correction. The additional internal states needed for polyqubit processing are already present in atomic processors, suggesting that the resource cost associated with this multiplicative increase in qubit number could be a good bargain in the short to medium term.
