About dwave-gate#

dwave-gate is a software package for constructing, modifying and running quantum circuits on the included simulator. It provides a set of tools that enables you to:

  • Construct quantum circuits using an intuitive context-manager interface.

  • Utilize a comprehensive library of quantum gates with simple access to matrix representations, various decompositions, and more.

  • Simulate circuits on a performant (C++) state-vector simulator.

  • Easily create your own quantum gates and templates. Any circuit can be either directly applied in another circuit or converted into a quantum operation.

This example uses the dwave.gate.Circuit object’s context manager to append operations to a two-qubit circuit.

>>> import dwave.gate.operations as ops
>>> from dwave.gate import Circuit

>>> circuit = Circuit(2)

>>> with circuit.context as (q, c):     
...    ops.X(q[0])
...    ops.Hadamard(q[1])
...    ops.CZ(q[0], q[1])
...    ops.Hadamard(q[1])

You can run the dwave.gate.simulator simulator on such circuits,

>>> from dwave.gate.simulator import simulate
>>> simulate(circuit)

and then access the resulting state via the state attribute.

>>> circuit.state   
array([0.+0.j, 0.+0.j, 0.+0.j, 1.+0.j])
