Quantum signature of gravity in optomechanical systems with conditional measurement [PDF]
Physical Review D, 2023 We investigate the quantum signature of gravity in optomechanical systems under quantum control. We analyze the gravity-induced entanglement and squeezing in mechanical mirrors in a steady state.

Digital Signatures with Quantum Candies [PDF]
Entropy, 2022 Quantum candies (qandies) represent a type of pedagogical simple model that describes many concepts from quantum information processing (QIP) intuitively without the need to understand or make use of superpositions and without the need of using complex algebra. One of the topics in quantum cryptography that has gained research attention in recent years

A Quantum Dual-Signature Protocol Based on SNOP States without Trusted Participant
Entropy, 2021 Quantum dual-signature means that two signed quantum messages are combined and expected to be sent to two different recipients. A quantum signature requires the cooperation of two verifiers to complete the whole verification process.

Quantum Digital Signatures without Quantum Memory [PDF]
Physical Review Letters, 2014 Quantum Digital Signatures (QDS) allow for the exchange of messages from one sender to multiple recipients, with the guarantee that messages cannot be forged or tampered with. Additionally, messages cannot be repudiated -- if one recipient accepts a message, she is guaranteed that others will accept the same message as well.

Twin-field quantum digital signatures [PDF]
Optics Letters, 2021 Digital signature is a key technique in information security, especially for identity authentications. Compared to classical correspondence, quantum digital signatures (QDSs) provide a considerably higher level of security. At present, its performance is limited by key generation protocols, which are fundamentally limited in terms of channel capacity ...

Two Quantum Proxy Blind Signature Schemes Based on Controlled Quantum Teleportation
Entropy, 2022 We present a scheme for teleporting an unknown, two-particle entangled state with a message from a sender (Alice) to a receiver (Bob) via a six-particle entangled channel.

Quantum Tokens for Digital Signatures [PDF]
, 2023 The fisherman caught a quantum fish. "Fisherman, please let me go", begged the fish, "and I will grant you three wishes". The fisherman agreed. The fish gave the fisherman a quantum computer, three quantum signing tokens and his classical public key. The

Multiparty quantum signature schemes [PDF]
Quantum Information and Computation, 2016 Digital signatures are widely used in electronic communications to secure important tasks such as financial transactions, software updates, and legal contracts. The signature schemes that are in use today are based on public-key cryptography and derive their security from computational assumptions.
