D-Wave Systems Inc. is a company that develops and manufactures quantum computers based on quantum annealing. However, it's important to note that D-Wave's systems are not designed with the same architecture as universal gate-based quantum computers. Therefore, they do not possess traditional RAM (Random Access Memory) in the same sense as classical computers.
D-Wave's quantum computers use a different model called "qubits," which are the fundamental units of quantum information. Qubits are not directly analogous to classical bits or traditional RAM. Instead, qubits represent the quantum states of superposition and entanglement.
D-Wave's latest generation of quantum computers, known as the D-Wave 2000Q system, has 2048 qubits. These qubits can be used to encode and process information for solving certain optimization problems using quantum annealing.
It's worth noting that the number of qubits does not directly translate to classical memory or RAM as it is understood in classical computing. The properties and capabilities of qubits are fundamentally different from classical bits, and their usage and behavior are specific to the quantum computing paradigm.
