Syntax
- traceOut(name)
Description
traceOut(name) traces out the subsystem name. The resulting reduced density matrices are safed in the variable reduced_rho_hist. Further operations can be performed on these matrices manually and the getConcurrence method relies on them. Mathematically the reduced density matrix is generated by
where n_i are the kronecker expanded basis vectors of subsystem name.
