Quantum information

量子信息是一个涉及物理学和计算机科学的相对较新的领域。量子信息研究人员研究量子力学如何影响我们处理信息的能力。事实证明，量子力学可以帮助解决计算任务，执行分布式计算和执行新的加密协议。这也是一个使用属于计算机科学的工具、思想和概念来研究量子力学的领域。虽然这个领域还很年轻，但它已经取得了极大的成功。在这个提议中，我希望解决计算机科学如何帮助理解物理学以及量子力学如何用于解决有用的计算任务。首先，我计划研究量子计算机如何比经典计算机更有效地计算功能。计算机科学也对分布式计算问题感兴趣，其中通信量是主要关注的问题。我们知道纠缠有时可以用来减少交流。我打算研究纠缠和沟通的关系。量子信息非常成功的领域之一是密码学。我还希望研究如何使用量子信息使一组实体能够在不泄露宝贵机密信息的情况下对私人数据进行计算。最后，我想学习量子交互证明。

Quantum information is a relatively new field that involves physics and computer science. Researchers involved in quantum information study how quantum mechanics can influence our capacity to process information. It turns out that quantum mechanics can help in solving computational tasks, performing distributed computation and performing new cryptographic protocols. It is also a field where quantum mechanics is studied using the tools, ideas and concepts belonging to computer science. Although the field is young, it has been extremely successful. In this proposal, I wish to address both how computer science can help to understand physics and how quantum mechanics can be used to solve useful computational tasks. First, I plan to study how the quantum computer can compute functions more efficiently than the classical computer. Computer science is also interested in distributed computation problems where the amount of communication is the main concern. We know that entanglement can some times be used to reduce communication. I plan to study the relationship between entanglement and communication. One of the areas where quantum information was extremely successful is cryptography. I also wish to study how quantum information can be used to enable a group of entities to perform computation on private data without revealing precious confidential information. Finally, I wish to study quantum interactive proofs.
