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…

Quantum-as-a-Service (QaaS)
Quantum-as-a-Service (QaaS) - also called Quantum Computing as a Service (QCaaS) - is essentially cloud-based access to quantum computing resources. In simple terms, a third-party hosts quantum computers (and related software tools) in the cloud, and users access those quantum capabilities remotely over the internet. This model parallels other “as-a-Service”…
