Quantum communication and quantum computation are expected to establish a new paradigm in information technology and advance our understanding of quantum mechanics. It is considered that it will provide cryptography that can not be decoded and super parallel computation that is much faster than that of ordinary computers for certain applications. Besides these technical issues intriguing questions concerning quantum mechanical phenomena can be addressed, hi quantum communication and quantum computation, entanglement plays an important role. It contributes to the high-speed parallel computation and is a necessary resource for quantum communication such as quantum teleportation, super dense coding and high-speed transmission by quantum repeaters. For their realization, multi-qubit devices need to be engineered that use entanglement on a mesoscopic and macroscopic scale.

量子通信和量子计算有望建立信息技术的新范式，并促进我们对量子力学的理解。它被认为将提供不可破译的密码学和比普通计算机快得多的超并行计算，以用于某些应用。除了这些技术问题之外，量子力学现象的一些有趣的问题也可以得到解决。在量子通信和量子计算中，纠缠起着重要的作用。它有助于高速并行计算，是量子隐形传态、超密集编码和量子中继器高速传输等量子通信的必要资源。为了实现它们，需要设计多量子比特设备，在介观和宏观尺度上使用纠缠。
