A comprehensive survey on quantum computer usage: How many qubits are employed for what purposes?
Tsubasa Ichikawa, Hideaki Hakoshima, Koji Inui +18
Quantum computers (QCs), which work based on the law of quantum mechanics, are expected to be faster than classical computers in several computational tasks such as prime factoring…
Quantum-inspired algorithm applied to extreme learning
Iori Takeda, Souichi Takahira, Kosuke Mitarai +1
Quantum-inspired singular value decomposition (SVD) is a technique to perform SVD in logarithmic time with respect to the dimension of a matrix, given access to the matrix embedded…
Quantum Algorithms based on the Block-Encoding Framework for Matrix Functions by Contour Integrals
Souichi Takahira, Asuka Ohashi, Tomohiro Sogabe +1
The matrix functions can be defined by Cauchy's integral formula and can be approximated by the linear combination of inverses of shifted matrices using a quadrature formula. In th…
