Two-level Quantum Walkers on Directed Graphs II: An Application to qRAM
Ryo Asaka, Kazumitsu Sakai, Ryoko Yahagi
This is the second paper in a series of two. Using a multi-particle continuous-time quantum walk with two internal states, which has been formulated in the first paper (arXiv:2112.…
Two-level Quantum Walkers on Directed Graphs I: Universal Quantum Computing
Ryo Asaka, Kazumitsu Sakai, Ryoko Yahagi
In the present paper, the first in a series of two, we propose a model of universal quantum computation using a fermionic/bosonic multi-particle continuous-time quantum walk with t…
Quantum random access memory via quantum walk
Ryo Asaka, Kazumitsu Sakai, Ryoko Yahagi
A novel concept of quantum random access memory (qRAM) employing a quantum walk is provided. Our qRAM relies on a bucket brigade scheme to access the memory cells. Introducing a bu…
Quantum circuit for the fast Fourier transform
Ryo Asaka, Kazumitsu Sakai, Ryoko Yahagi
We propose an implementation of the algorithm for the fast Fourier transform (FFT) as a quantum circuit consisting of a combination of some quantum gates. In our implementation, a…
