Run

bool qsim::HybridSimulator::Run(
  const Parameter & param,
  HybridData & hd,
  const std::vector< unsigned > & parts,
  const std::vector< GateFused > & fgates0,
  const std::vector< GateFused > & fgates1,
  const std::vector< uint64_t > & bitstrings,
  std::vector< std::complex< fp_type >> & results
) const

Runs the hybrid simulator on a sectioned lattice.

Details
Parameters
param
Options for parallelism and logging. Also specifies the size of the 'prefix' and 'root' sections of the lattice.
hd
Container object for gates on the boundary between lattice sections.
parts
Lattice sections to be simulated.
fgates0
List of gates from one section of the lattice.
fgates1
List of gates from the other section of the lattice.
bitstrings
List of output states to simulate, as bitstrings.
results
Output vector of amplitudes. After a successful run, this will be populated with amplitudes for each state in 'bitstrings'.
Returns
True if the simulation completed successfully; false otherwise.

Public static functions

SplitLattice

bool qsim::HybridSimulator::SplitLattice(
  const std::vector< unsigned > & parts,
  const std::vector< Gate > & gates,
  HybridData & hd
)

Splits the lattice into two parts, using Schmidt decomposition for gates on the cut.

Details
Parameters
parts
Lattice sections to be simulated.
gates
List of all gates in the circuit.
hd
Output data with splitted parts.
Returns
True if the splitting done successfully; false otherwise.
