Decay of a quasi-stable quantum system and quantum backflow
Wytse van Dijk, F. Masafumi Toyama
The decay of quasi-stable quantum system involves primarily an outgoing probability current density. However, during the transition from exponential to inverse-power-law decay ther…
Additive decomposition of iterative quantum search operations in the Grover-type algorithm
F. M. Toyama, W. van Dijk
In the Grover-type quantum search process a search operator is iteratively applied, say, k times, on the initial database state. We present an additive decomposition scheme such th…
Numerical solutions of the Schrodinger equation with source terms or time-dependent potentials
W. van Dijk, F. M. Toyama
We develop an approach to solving numerically the time-dependent Schrodinger equation when it includes source terms and time-dependent potentials. The approach is based on the gene…
Multi-phase matching in the Grover algorithm
F. M. Toyama, W. van Dijk, Y. Nogami +2
Phase matching has been studied for the Grover algorithm as a way of enhancing the efficiency of the quantum search. Recently Li and Li found that a particular form of phase matchi…
Accurate numerical solutions of the time-dependent Schrödinger equation
W. van Dijk, F. M. Toyama
We present a generalization of the often-used Crank-Nicolson (CN) method of obtaining numerical solutions of the time-dependent Schrödinger equation. The generalization yields nume…
Conditional Expressions for Blind Deconvolution: Derivative form
S. Aogaki, I. Moritani, T. Sugai +2
We developed novel conditional expressions (CEs) for Lane and Bates' blind deconvolution. The CEs are given in term of the derivatives of the zero-values of the z-transform of give…
