Introduction
D-Wave Systems is a Canadian company that develops and manufactures quantum computers. D-Wave quantum computers are based on quantum annealing, a type of quantum algorithm that is particularly well-suited for solving optimization problems.
How D-Wave Quantum Computers Work
D-Wave quantum computers use a technology called superconducting qubits. These qubits are able to exist in a superposition of states, which means that they can be both 0 and 1 at the same time. This ability gives quantum computers a significant advantage over classical computers, which can only be in one state at a time.
The process of quantum annealing starts by encoding the optimization problem into the state of the qubits. The qubits are then cooled to near absolute zero, which allows them to enter a quantum state. The system is then allowed to evolve over time, with the qubits interacting with each other. Finally, the qubits are measured, and the results are used to find the optimal solution to the problem.
Applications of D-Wave Quantum Computers
D-Wave quantum computers have a wide range of potential applications, including:
