# D-Wave Systems

D-Wave Systems is a Canadian company that specializes in designing, developing, and manufacturing quantum computers. The company is headquartered in Burnaby, British Columbia and was founded in 1999 by Geordie Rose and Bob Wienski. The company has become a leader in the field of quantum computing, and its current system is the D-Wave 2X, which has over 1,000 qubits.

D-Wave’s quantum computing technology works differently than traditional computers. Conventional computers are made up of bits – electronic switches that can either be on or off. A bit can represent either a 1 or a 0, and by combining these digits, we can perform calculations, solve problems, and so on. Quantum computers, however, use qubits (quantum bits) that have a much more complex relationship with one another. Qubits can exist in multiple states at the same time, which leads to a phenomenon called quantum entanglement. This means that qubits can be used to perform calculations in parallel, which makes quantum computing much faster than classical computing for certain types of problems.

D-Wave’s quantum computers use a process called quantum annealing to solve optimization problems. In this process, qubits are arranged in a way that represents the problem to be solved, and then the qubits are allowed to evolve over time, using quantum entanglement to find the lowest energy state – this solution is the optimal solution to the problem. This process takes advantage of the fact that certain types of optimization problems can be reduced to finding the lowest energy state of a complex system, making quantum annealing a promising strategy for tackling these types of problems.

One of the biggest challenges facing D-Wave and other quantum computing companies is the stability of their qubits. Qubits are notoriously difficult to control, and even minor disruptions or interference from the environment can lead to errors in the computations. To overcome this challenge, D-Wave has developed a number of strategies, such as using a process called error correction, to reduce the likelihood of errors occurring. However, quantum computing is still in its infancy, and there is much work to be done before it becomes a commercial reality.

Despite these challenges, D-Wave has made significant progress in the field of quantum computing. Its systems have been used to tackle a range of optimization problems, such as scheduling problems in transportation, and have shown impressive results in some cases. The company has also formed a number of partnerships with other tech companies.
