qsim:: CircuitQsimParser


   #include <circuit_qsim_parser.h>

Parser for the (deprecated) qsim file input format .

Summary

The primary supported interface for designing circuits to simulate with qsim is Cirq , which relies on the Python-based qsimcirq interface. For C++ applications, Cirq gates can be explicitly constructed in code.

Public static functions
`FromFile (unsigned maxtime, const std::string & file, Circuit < GateQSim < fp_type >> & circuit)`	`bool` Parses the given file into a Circuit object, following the rules defined in "docs/input_format.md".
`FromStream (unsigned maxtime, const std::string & provider, Stream & fs, Circuit < GateQSim < fp_type >> & circuit)`	`bool` Parses the given input stream into a Circuit object, following the rules defined in "docs/input_format.md".

Public static functions

FromFile

bool FromFile(
  unsigned maxtime,
  const std::string & file,
  Circuit< GateQSim< fp_type >> & circuit
)

Parses the given file into a Circuit object, following the rules defined in "docs/input_format.md".

Details

Parameters

`maxtime`	Maximum gate "time" to read operations for (inclusive).
`file`	The name of the file to read the circuit from.
`circuit`	Output circuit object. If parsing is successful, this will contain the circuit defined in 'file'.

Returns

True if parsing succeeds; false otherwise.

FromStream

bool FromStream(
  unsigned maxtime,
  const std::string & provider,
  Stream & fs,
  Circuit< GateQSim< fp_type >> & circuit
)

Parses the given input stream into a Circuit object, following the rules defined in "docs/input_format.md".

Details

Parameters

`maxtime`	Maximum gate "time" to read operations for (inclusive).
`provider`	Circuit source; only used for error reporting.
`fs`	The stream to read the circuit from.
`circuit`	Output circuit object. If parsing is successful, this will contain the circuit defined in 'fs'.

Returns

True if parsing succeeds; false otherwise.
