RFOX (Rotated-Field Oscillatory eXchange) quantum algorithm: Towards Parameter-Free Quantum Optimizers

Brian García Sarmina, Guo-Hua Sun, Shi-Hai Dong

We introduce RFOX (Rotated-Field Oscillatory eXchange), a parameter-free quantum algorithm for combinatorial optimization that combines an almost constant non-stoquastic catal…

Q-PIPE A Practical Quantum Phase Encoding Method

Brian García Sarmina, Emmanuel Martínez-Guerrero, Janeth De Anda Gil +2

A major hurdle in Quantum Image Processing (QIMP) is efficiently transferring classical, high-dimensional image data into quantum states. Current methods face trade-offs: amplitude…

Exploring Entanglement and Parameter Sensitivity in QAOA through Quantum Fisher Information

Brian García Sarmina, Jorge Saavedra Benavides, Guo-Hua Sun +1

Quantum Fisher Information (QFI) can be used to quantify how sensitive a quantum state reacts to changes in its variational parameters, making it a natural diagnostic for algorithm…
