D-Wave Technology 

D-Wave’s quantum computer leverages quantum dynamics to accelerate and enable new methods for solving discrete optimization, sampling, material science, and machine learning problems. It uses a process called quantum annealing that harnesses the natural tendency of real-world quantum systems to find low-energy states. If an optimization problem is analogous to a landscape of peaks and valleys, each coordinate represents a possible solution and its elevation represents its energy. The best solution is that with the lowest energy corresponding to the lowest point in the deepest valley in the landscape.

In 2010 we released our first commercial system, the D-Wave One™ quantum computer. We have doubled the number of qubits in successive generations, shipping the 512-qubit D-Wave Two™ system in 2013 and the 1000+ qubit D-Wave 2X™ system in 2015. In 2017 we released the D-Wave 2000Q™ system with 2000 qubits and advanced control features.

 

State of the Business 

D-Wave has installed more than $50 million worth of quantum systems at customer sites. The D-Wave 2000Q system is available through sale or lease as a standalone system, or via our quantum cloud. We also provide competition-winning, quantum-inspired machine learning services, application development services, and custom fabrication of superconducting circuits.

We and our customers have developed dozens of prototype applications and software tools, many of which have been published and presented at conferences and user forums. We have a dedicated sales and systems engineering team including experts who train and assist our customers in developing applications.

We have been the subject of a cover story in Time, and of major coverage in The New York Times, Wired, MIT Technology Review, The Wall Street Journal, and The Economist.

 

Quantum Applications

D-Wave and its customers, new quantum software companies, and independent developers are developing system software, higher-level tools, and applications that leverage the power of the D-Wave system. Users have already developed over 100 early applications in areas including:

  • Optimization 

  • Machine learning 

  • Pattern recognition and anomaly detection 

  • Cyber security 

  • Image analysis 

  • Financial analysis 

Applications

More than 100 applications run on Dwave Q

OPTIMATIZATION

A

Imagine you are building a house, and have a list of things you want to have in your house, but you can’t afford everything on your list because you are constrained by a budget. What you really want to work out is the combination of items which gives you the best value for your money.

This is an example of a optimization problem, where you are trying to find the best combination of things given some constraints. While problems with only a few choices are easy, as the number of choices grows, they quickly get very hard to solve optimally. With just 270 on/off switches, there are more possible combinations than atoms in the universe!

These types of optimization problems exist in many different domains, such as systems design, mission planning, airline scheduling, financial analysis, web search, and cancer radiotherapy. They are some of the most complex problems in the world, with potentially enormous benefits to businesses, people and science if optimal solutions can be readily computed.

MACHINE LEARNING

B

When you look at a photograph it is very easy for you to pick out the different objects in the image: trees, mountains, velociraptors etc. This task is almost effortless for humans, but is in fact a hugely difficult task for computers to achieve. This is because programmers don’t know how to define the essence of a ‘tree’ in computer code.

Machine learning is the most successful approach to solving this problem, by which programmers write algorithms that automatically learn to recognize the ‘essences’ of objects by detecting recurring patterns in huge amounts of data. Because of the amount of data involved in this process, and the immense number of potential combinations of data elements, this is a very computationally-expensive optimization problem. As with other optimization problems, these can be mapped to the native capability of the D-Wave QPU

MONTE CARLO SIMULATION

C

Many things in the world are uncertain, and governed by the rules of probability. We have in our heads a model of how things will turn out in the future, and the better our model is, the better we are at predicting the future. We can also build computer models to try and capture the statistics of reality. These tend to be very complicated, involving a huge number of variables.

In order to check to see if a computer’s statistical model represents reality we need to be able to draw samples from it, and check that the statistics of our model match the statistics of real world data. Monte Carlo simulation, which relies on repeated random sampling to approximate the probability of certain outcomes, is an approach used in many industries such as finance, energy, manufacturing, engineering oil and gas and the environment. For a complex model, with many different variables, this is a difficult task to do quickly.

MATERIALS SIMULATION

D

In 1981, Nobel Prize–winning physicist Richard Feynman delivered his seminal lecture “Simulating Physics with Computers”. His idea was that unlike a classical computer which could only approximate a simulation of physics, a quantum computer could simulate it exactly – as quantum physics. In a paper published in 1982 he said, “I therefore believe it's true that with a suitable class of quantum machines you could imitate any quantum system, including the physical world.”  

Today quantum materials simulation is being actively pursued by scientists around the world, and some see it as the first “killer application” for quantum computers.
