无量子位量子逻辑

Qubitless Quantum Logic

Richard B. Kassman, Gennady P. Berman, Vladimir I. Tsifrinovich, Gustavo V. Lopez

摘要:

我们讨论了量子逻辑在强相互作用粒子系统中的实现。这种实现是无量子位的,因为"逻辑量子比特"不对应于任何物理双态子系统。作为一个例子,我们提出的量子控制非门和Shor的算法的模拟结果的自旋1/2的粒子链海森堡耦合。我们的建议扩展了当前的量子信息处理理论,包括系统之间的两个状态的子系统的永久强耦合。

英文摘要:

We discuss the implementation of quantum logic in a system of strongly interacting particles. The implementation is qubitless since ``logical qubits'' don't correspond to any physical two-state subsystems. As an illustration, we present the results of simulations of the quantum controlled-NOT gate and Shor's algorithm for a chain of spin-1/2 particles with Heisenberg coupling. Our proposal extends the current theory of quantum information processing to include systems with permanent strong coupling between the two-state subsystems.
