Agnostic learning of qudit stabilizer states
Wentao Qi, Boyan Xu, Shiguang Feng +1
Learning a classical description of a quantum state is a fundamental task in quantum computation. Among the most important classes of quantum states are stabilizer states, which pl…
Arbitrary state creation via controlled measurement
Alexander I. Zenchuk, Wentao Qi, Junde Wu
The initial state creation is a starting point of many quantum algorithms and usually is considered as a separate subroutine not included into the algorithm itself. There are many…
Matrix encoding method in variational quantum singular value decomposition
Alexander I. Zenchuk, Wentao Qi, Junde Wu
We propose the variational quantum singular value decomposition based on encoding the elements of the considered { } matrix into the state of a quantum system of appropr…
Quantumly controlled measurement, Hermitian conjugation and normalization in matrix-manipulation algorithms
Edward B. Fel'dman, Alexander I. Zenchuk, Wentao Qi +1
In this paper, we solve three important problems that are revealed, in particular, to matrix-manipulation algorithms. The principal novelty is introducing the concept of quantumly…
Remarks on controlled measurement and quantum algorithm for calculating Hermitian conjugate
Edward B. Fel'dman, Alexander I. Zenchuk, Wentao Qi +1
We present two new aspects for the recently proposed algorithms for matrix manipulating based on the special encoding the matrix elements into the superposition state of a quantum…
