The collective noises, which include the collective-dephasing noise and the collective-
rotation noise, are the topical noises in quantum key agreement (QKA). How to eliminate the …

In this paper, we present a trusted third-party e-payment protocol which is designed based
on quantum blind signature without entanglement. The security and verifiability of our …

We propose an arbitrated quantum signature (AQS) scheme with continuous variable (CV)
squeezed vacuum states, which requires three parties, ie, the signer Alice, the verifier Bob …

We propose a quantum voting scheme with Greenberger-Horne-Zeilinger (GHZ) states. In
this scheme, quantum sequences that are formed by different particles of different GHZ …

In this paper, we present a multi-proxy weak blind signature scheme based on quantum
entanglement swapping of Bell states. In the scheme, proxy signers can finish the signature …

An improved quantum proxy blind signature scheme based on controlled teleportation is
proposed in this paper. Genuine seven-qubit entangled state functions as quantum channel …

A novel arbitrated quantum signature (AQS) scheme is proposed motivated by the
Hamiltonian algorithm (HA) and blind quantum computation (BQC). The generation and …

We present an arbitrated quantum blind signature scheme by entanglement swapping,
which is simplified from the preparation and operation of the quantum states. Compared with …

In this paper, we present an offline arbitrated quantum blind dual-signature protocol by using
four-particle entangled Greenberger-Horne-Zeilinger (GHZ) states. By using the special …

A new quantum bi-signature scheme based on GHZ states and W states is proposed. In the
proposed scheme, Alice and Bob sign one same message and send their signatures to …
