Quantum signatures in the quantum Carnot cycle
New Journal of Physics, 2020 The Carnot cycle combines reversible isothermal and adiabatic strokes to obtain optimal efficiency, at the expense of a vanishing power output. Quantum Carnot-analog cycles are constructed and solved, operating irreversibly with positive power.

Quantum signatures of breather-breather interactions [PDF]
Physical Review Letters, 2003 The spectrum of the Quantum Discrete Nonlinear Schr\"odinger equation on a periodic 1D lattice shows some interesting detailed band structure which may be interpreted as the quantum signature of a two-breather interaction in the classical case.

Unconditionally Secure Quantum Signatures [PDF]
Entropy, 2015 Signature schemes, proposed in 1976 by Diffie and Hellman, have become ubiquitous across modern communications. They allow for the exchange of messages from one sender to multiple recipients, with the guarantees that messages cannot be forged or tampered

A Quantum Proxy Signature Scheme Without Restrictions on the Identity and Number of Verifiers [PDF]
EntropyQuantum digital signatures (QDS) establish a framework for information-theoretically secure authentication in quantum networks. As a specialized extension of QDS, quantum proxy signatures facilitate secure delegation of signing privileges in distributed ...

Quantum Digital Signature Using Entangled States for Network [PDF]
EntropyWe propose an entanglement-based quantum digital signature (QDS) protocol optimized for quantum networks. The protocol follows the Lamport-inspired QDS paradigm but eliminates QKD post-processing by signing and verifying with raw conclusive keys, thereby
