Sequential Quantum Multiparty Signature Based on Quantum Fourier Transform and Chaotic System

IEEE Access, 2020
Motivated by the quantum Fourier transform (QFT), a sequential quantum multiparty signature (QMS) scheme is proposed. Several signatories jointly accomplish the task in a chaotic encryption system. Alice generates and sends the encrypted message with the

Simulation of Limited Entangled Quantum Fourier Transform Based on Matrix Product State [PDF]

Jisuanji kexue
Unlike classical computing,qubits in quantum computing can be in the superposition state and entangled state can be formed between multiple qubits.Representing a quantum state composed of n qubits requires storing 2 to the nth power amplitudes.The ...

De-quantisation of the quantum Fourier transform [PDF]

Applied Mathematics and Computation, 2012
The quantum Fourier transform (QFT) plays an important role in many known quantum algorithms such as Shor's algorithm for prime factorisation. In this paper we show that the QFT algorithm can, on a restricted set of input states, be de-quantised into a classical algorithm which is both more efficient and simpler than the quantum algorithm.
