Divide-and-Conquer Simulation of Open Quantum Systems
Thiago Melo D. Azevedo, Caio Almeida, Pedro Linck +2
One of the promises of quantum computing is to simulate physical systems efficiently. However, the simulation of open quantum systems - where interactions with the environment play…
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…
Distillation of quantum non-Markovianity
Thiago Melo D. Azevedo, Cristhiano Duarte, Nadja K. Bernardes
Non-Markovianty of open quantum systems dynamics is a physically relevant property which is usually associated with the backflow of (quantum) information. Using this paradigmatic m…
