Abstract: Quantum cryptography is one of the first and most developed quantum technology, with notable progress in quantum communications and quantum networking in the past years. Initially presented...
Abstract: Classical information can be completely hidden in the correlations of bipartite quantum systems. However, it is impossible to hide or mask all quantum information according to the no-hiding...
Abstract: Quantum key distribution (QKD) establishes secure links between remote communication partners. As a key problem for various QKD protocols, security analysis gives the number of secret keys ...
Abstract: An outstanding challenge of quantum computing is to build quantum devices with both excellent coherence and reliable universal control [1]. Ancilla systems are often indispensable to univer...
Abstract: Quantum cooling, a deterministic process that drives any state to the lowest eigenstate, has been widely used from studying ground state properties of chemistry and condensed matter quantum...
Abstract: Random quantum states and operations are of fundamental and practical interests. In this work, we investigate the entanglement properties of random hypergraph states, which generalize the n...
