Title:
Imaginary-time evolution algorithm on quantum computers and its perspective
on quantum chemical calculations
Abstract：
Currently, quantum chemical calculations using quantum computers are
attracting a great deal of attention. We have been developing algorithms for
quantum chemical calculations using quantum computers. In particular, we
have recently focused on the imaginary-time evolution method. Note that
algorithms using quantum computers must be expressed in terms of unitary
operations and observations for each qubit. Therefore, it was a nontrivial
problem how to perform the imaginary-time evolution operator, which is a
non-unitary operation, on a quantum computer. We have developed a method to
implement the imaginary-time evolution algorithm in a form using auxiliary
bits and proposed a method of first-quantized eigensolver for quantum
chemistry for ground states based on the imaginary-time evolution method
[1]. Furthermore, we have been working on developing algorithms to reduce
errors when performing calculations on quantum computers [2]. In this
presentation, we will discuss the fundamentals of quantum computers, the
implementation of the imaginary-time evolution algorithm, the computational
cost of implementing the imaginary-time evolution algorithm for materials
calculations, and the error mitigation algorithms we have been developing.
