Memory-built-in quantum cloning in a hybrid solid-state spin register
Memory-built-in quantum cloning hybrid solid-state spin register
2016/1/22
As a way to circumvent the quantum no-cloning theorem, approximate quantum cloning protocols have received wide attention with remarkable applications. Copying of quantum states to memory qubits provi...
Improved Efficiency for CCA-Secure Cryptosystems Built Using Identity Based Encryption
Cryptosystems Built Identity Based Encryption
2015/8/5
Recently, Canetti, Halevi, and Katz showed a general method for constructing CCA-secure encryption from identity-based encryption in the standard model. We improve the efficiency of their construction...
