We know that quantum computing is a complex subject, but the resources section has content aimed at people with differing levels of knowledge. Watch a video, read a tutorial or white paper or one of the many scientific papers that have been published about all aspects of D-Wave and quantum computing. 


Quantum computing is not a familiar topic to most people, nor is programming a quantum computer. Our tutorials provide background information for those interested in understanding quantum computers and how to program them.

How D-Wave processors are built, and how they use the physics of spin systems to implement quantum computation The aim of this document is to describe how a quantum computer is physically built, how quantum bits and their associated circuitry are created, addressed, and controlled, and what is happening inside the computer when programmers send information to a D-Wave quantum machine.


D-Wave has published more than 70 peer-reviewed papers in scientific journals including Nature, Science, Physical Review and others. There are also many other papers written by independent scientists about the D-Wave technology. You can find links to them from the publications page.

The work of Berezinskii, Kosterlitz and Thouless in the 1970s revealed exotic phases of matter governed by the topological properties of low-dimensional materials such as thin films of superfluids and superconductors. A hallmark of this phenomenon is the appearance and interaction of vortices and antivortices in an angular degree of freedom—typified by the classical XY model—owing to thermal fluctuations. In the two-dimensional Ising model this angular degree of freedom is absent in the classical case, but with the addition of a transverse field it can emerge from the interplay between frustration and quantum fluctuations. Consequently, a Kosterlitz–Thouless phase transition has been predicted in the quantum system—the two-dimensional transverse-field Ising model—by theory and simulation. Here we demonstrate a large- scale quantum simulation of this phenomenon in a network of 1,800 in situ programmable superconducting niobium flux qubits whose pairwise couplings are arranged in a fully frustrated square-octagonal lattice. Essential to the critical behaviour, we observe the emergence of a complex order parameter with continuous rotational symmetry, and the onset of quasi-long-range order as the system approaches a critical temperature. We describe and use a simple approach to statistical estimation with an annealing-based quantum processor that performs Monte Carlo sampling in a chain of reverse quantum annealing protocols. Observations are consistent with classical simulations across a range of Hamiltonian parameters. We anticipate that our approach of using a quantum processor as a programmable magnetic lattice will find widespread use in the simulation and development of exotic materials.
