Information processing based on the laws of quantum mechanics offers the promise of revolutionary advances in computing and communication. Quantum algorithms can perform certain tasks dramatically faster than today's fastest computers, and novel protocols such as teleportation and quantum cryptography can transform our current communication and information processing capabilities. Small-scale quantum information processing (QIP) has been demonstrated, but the challenge is to efficiently control multipartite coupled systems for large-scale QIP. These coupled systems can exhibit powerful non-classical correlations or 'entanglement' in the quantum regime, and nonlinear chaotic behaviour in the classical regime.

基于量子力学定律的信息处理为计算和通信提供了革命性的进步。量子算法可以比当今最快的计算机更快地执行某些任务，而诸如隐形传态和量子密码学等新协议可以改变我们目前的通信和信息处理能力。小规模量子信息处理（QIP）已经被证明，但挑战是有效地控制大规模QIP的多体耦合系统。这些耦合系统可以表现出强大的非经典关联或“纠缠”的量子制度，在经典制度和非线性混沌行为。
