摘　　要：讨论了用一维简谐势阱中的 Bose- Einstein凝聚体 (BECs)制成的多原子级非平衡 Schrodinger猫态作为量子计算机中的量子位 ,在此基础上利用共振射频场对量子位作用的相差优化量子信息的计算结果 ,从而进行信息的读取 .并从单个量子位推广到多量子位系统 .The preparation of a quantum bit(qubit)in the quantum computer was discussed by using a multi-atomic unbalanced Schrdinger's cat state made from Bose-Einstein Condensates(BECs)in the one-dimensional harmonic potential.The acquirement of quantum information was performed by means of the dephasing of radiation field's acting on qubits to optimizq the information computation results.The extension from one qubit to the multi-qubit system was also considered.
