 =======
 The pytket-quantinuum extension allows the user to access the following quantum devices, emulators and syntax checkers. These backends can be initialised  by passing the device name as a string to the ``QuantinuumBackend`` class. The available devices are:
 
-* ``H1-1``, ``H1-2``, ``H2-1``: Quantum devices, submit specifically to ``H1-1``, ``H1-2`` or ``H2-1`` by using the device name.
-* ``H1-1E``, ``H1-2E``, ``H2-1E``: Device-specific emulators of ``H1-1``, ``H1-2`` and ``H2-1``. These emulators run remotely on servers and require credentials.
-* ``H1-1SC``, ``H1-2SC``, ``H2-1SC``: Device-specific syntax checkers. These check compilation of a quantum circuit against device-specific instructions, and return status "completed" if the syntax is correct (along with the H-Series Quantum Credits (HQCs)), or status "failed" if the syntax is incorrect (along with the error).
+* ``H1-1``, ``H2-1``: Quantum devices, submit specifically to ``H1-1`` or ``H2-1`` by using the device name.

 There are also optional initialisation parameters ``label`` (for naming circuits), ``group`` (identifier for a collection of jobs) and ``simulator`` (see below).
