There was a problem hiding this comment.
Looks good. Found a typo that can be dangerous.

changed the title
* Includes unitary method and superop method * Adds GPU version of superop simulation method
* Algorithm tests * Standard gate library tests * Save instruction tests
After trying the heuristic for stabilizer or density matrix simulation the remaining simulation methods are selected between based on supported instructions with ordering statevector > density matrix > matrix product state > unitary > superop.
There is a segfault happening somewhere so this disables the method until we can investigate further

Summary
Adds
AerSimulatorbackend that in the future will replace the QasmSimulator, StatevectorSimulator and UnitarySimulator backends.The
AerProviderhas been updated to include AerSimulator backends for all available methods and devices.Details and comments
C++ Controller
In the C++ code this adds a new
aer_controllerclass which is a combination of the previous base controller and qasm controller. The idea is in the future we do not need subclasses as all methods go through the same controller and the qasm_controller, unitary_controller and statevector_controller can be deprecated.New Backend
The main differences between the new
AerSimulatorbackend and theQasmSimulatorinclude:device='GPU'option for supported methods. egAerSimulator(method='statevector', device='GPU')save_stateor anothersaveinstruction, no final statevector or unitary will be returned automatically without the save instruction.Tests
Started refactoring tests to improve running common tests on all supported methods and devices.
Currently some of these tests are failing
