Combinatorial optimization solving by coherent Ising machines based on spiking neural networks
Bo Lu, Yong-Pan Gao, Kai Wen +1
Spiking neural network is a kind of neuromorphic computing that is believed to improve the level of intelligence and provide advantages for quantum computing. In this work, we addr…
A Coherent Ising Machine Based On Degenerate Optical Parametric Oscillators
Zhe Wang, Alireza Marandi, Kai Wen +2
A degenerate optical parametric oscillator network is proposed to solve the NP-hard problem of finding a ground state of the Ising model. The underlying operating mechanism origina…
Landau-Zener transition stabilized by the enhanced quantum Zeno effect in the bosonic system
Kai Wen, Tim Byrnes, Yoshihisa Yamamoto
We study the Landau-Zener transition with the quantum Zeno effect in an open dissipative system populated by a large number of bosons. Given the quantum Zeno effect is strong enoug…
Macroscopic quantum computation using Bose-Einstein condensates
Tim Byrnes, Kai Wen, Yoshihisa Yamamoto
Quantum computation using qubits made of two component Bose-Einstein condensates (BECs) is analysed. The use of BECs allows for an increase of energy scales via bosonic enhancement…
Unconditional Security of Single-Photon Differential Phase Shift Quantum Key Distribution
Kai Wen, Kiyoshi Tamaki, Yoshihisa Yamamoto
In this Letter, we prove the unconditional security of single-photon differential phase shift quantum key distribution (DPS-QKD) protocol, based on the conversion to an equivalent…
Reusable Vernam Cipher with Quantum Media
Kai Wen, Fu-Guo Deng, Gui Lu Long
A revised version will be uploaded later. In this Letter, it is shown that the one-time-pad key in the Vernam cipher can be repeatedly used with unconditional security using quantu…
