Quantum Multiplexer Simplification for State Preparation
José A. de Carvalho, Carlos A. Batista, Tiago M. L. de Veras +2
The initialization of quantum states or Quantum State Preparation (QSP) is a basic subroutine in quantum algorithms. In the worst case, general QSP algorithms are expensive due to…
Low-depth Quantum Circuit Decomposition of Multi-controlled Gates
Thiago Melo D. Azevedo, Jefferson D. S. Silva, Adenilton J. da Silva
Multi-controlled gates are fundamental components in the design of quantum algorithms, where efficient decompositions of these operators can enhance algorithm performance. The best…
Linear decomposition of approximate multi-controlled single qubit gates
Jefferson D. S. Silva, Thiago Melo D. Azevedo, Israel F. Araujo +1
We provide a method for compiling approximate multi-controlled single qubit gates into quantum circuits without ancilla qubits. The total number of elementary gates to decompose an…
Decomposition of Multi-controlled Special Unitary Single-Qubit Gates
Rafaella Vale, Thiago Melo D. Azevedo, Ismael C. S. Araújo +2
Multi-controlled unitary gates have been a subject of interest in quantum computing since its inception, and are widely used in quantum algorithms. The current state-of-the-art app…
Linear-depth quantum circuits for multiqubit controlled gates
Adenilton J. da Silva, Daniel K. Park
Quantum circuit depth minimization is critical for practical applications of circuit-based quantum computation. In this work, we present a systematic procedure to decompose multiqu…
Compact quantum kernel-based binary classifier
Carsten Blank, Adenilton J. da Silva, Lucas P. de Albuquerque +2
Quantum computing opens exciting opportunities for kernel-based machine learning methods, which have broad applications in data analysis. Recent works show that quantum computers c…
