Abstract— Two-level quantum systems are important quantum models that are useful for the conceptual development and construction of quantum technologies. In this paper we provide...

This letter proposes a novel key distribution protocol with no key exchange in advance, which is secure as the BB84 quantum key distribution protocol. Our protocol utilizes a phot...
We revisit the problem of conveying classical messages by transmitting quantum states, and derive new, optimal bounds on the number of quantum bits required for this task. Much of...
Multiple-valued quantum circuits are promising choices for future quantum computing technology, since the multiple-valued quantum system is more compact than the corresponding bina...
In this paper, we introduce 1-way and 2-way quantum nite state automata (1qfa's and 2qfa's), which are the quantum analogues of deterministic, nondeterministic and proba...
