Quantum Computing Benchmarks: RCS, QV, AQ, and More
As quantum computing hardware rapidly improves, simple metrics like qubit count are no longer sufficient to gauge a system’s true capability. Unlike classical computers where transistor counts roughly correlate with performance, quantum bits (qubits) can be error-prone and short-lived, so a few high-fidelity qubits can be more valuable than many…

Adiabatic Quantum (AQC) and Cyber (2024 Update)
Adiabatic Quantum Computing (AQC) is an alternative paradigm that uses an analog process based on the quantum adiabatic theorem. Instead of discrete gate operations, AQC involves slowly evolving a quantum system’s Hamiltonian such that it remains in its lowest-energy (ground) state, effectively “computing” the solution as the system’s final state.…

The Quantum Approximate Optimization Algorithm (QAOA) – A Beginner’s Guide
At its core, QAOA is a hybrid quantum-classical algorithm that constructs a special kind of quantum circuit (or “ansatz”) to represent a candidate solution, and then uses a classical optimizer to tweak that circuit for better results. It was introduced in 2014 by Edward Farhi and collaborators as an algorithm…
