I. Understanding Adiabatic Quantum Computers


A. Definition and basic principles


An adiabatic quantum computer operates by slowly manipulating the state of a system of qubits, gradually transforming them from an initial state to a final state that represents the solution to a specific problem. This slow, controlled process ensures the system remains in its ground state, the state with the lowest possible energy, throughout the computation. This feature differentiates it from other quantum computing approaches, such as gate-model quantum computers, which are more prone to errors due to their reliance on rapid manipulation of qubits.


B. Comparison with traditional computers and other types of quantum computers


Traditional computers operate on bits, which normally are either 0 or 1. In contrast, adiabatic quantum computers utilize qubits, which can exist as both 0 and 1 simultaneously. This superposition allows them to explore multiple solutions concurrently, making them significantly faster for specific types of problems.


Compared to other types of quantum computers, such as gate-model quantum computers, adiabatic computers excel at solving optimization problems where the goal is to find the best possible solution from a vast set of possibilities. However, they may not be as versatile for other types of computations.

Qubits: These are the quantum bits, often formed using superconducting circuits, trapped ions, or other quantum systems.


Hamiltonian: This mathematical function defines the energy landscape of the system and guides the evolution of the qubits.


Control system: This system manipulates external parameters, such as magnetic fields or voltages, to control the state of the qubits and steer them towards the desired solution.


During operation, the control system gradually changes the Hamiltonian, causing the qubits to evolve adiabatically. This controlled evolution ensures the system remains in its ground state, minimizing the risk of errors. By carefully designing the Hamiltonian and the control process, the computer can be programmed to solve specific optimization problems efficiently.
