Fields

isDensityMatrix: c_int

Whether this instance is a density-state representation

numQubitsRepresented: c_int

The number of qubits represented in either the state-vector or density matrix

numQubitsInStateVec: c_int

Number of qubits in the state-vector - this is double the number represented for mixed states

numAmpsPerChunk: c_longlong

Number of probability amplitudes held in stateVec by this process ! In the non-MPI version, this is the total number of amplitudes

numAmpsTotal: c_longlong

Total number of amplitudes, which are possibly distributed among machines

chunkId: c_int

The position of the chunk of the state vector held by this process in the full state vector

numChunks: c_int

Number of chunks the state vector is broken up into – the number of MPI processes used

stateVec: ComplexArray

Computational state amplitudes - a subset thereof in the MPI version

pairStateVec: ComplexArray

Temporary storage for a chunk of the state vector received from another process in the MPI version

deviceStateVec: ComplexArray

Storage for wavefunction amplitudes in the GPU version

firstLevelReduction: *mut f64

Storage for reduction of probabilities on GPU

secondLevelReduction: *mut f64

Storage for reduction of probabilities on GPU

cuStateVec: *mut c_void

Storage for wavefunction amplitues and config (copy of QuESTEnv’s handle) in cuQuantum deployment

deviceCuStateVec: *mut c_void

cuConfig: *mut *mut c_void

qasmLog: *mut QASMLogger

Storage for generated QASM output
