QuantumChar#
- class QuantumChar(qs=None, name=None, nisq_char=True)[source]#
A QuantumVariable which represents characters. By default, the QuantumChar is initialized in NISQ mode, meaning that instead of 256 characters it can only hold 32, saving almost 40% in qubit cost.

If
nisq_modeis set to False, the encoder uses the Python-inbuild chr function.
