[ 2.1.0 ] - [ 2021-04-xx ]

Added

Python bindings with MPI
new gate specialization for OpenMP performance improvement
distributed implementation of SWAP-type gates
class Permutation and method PermuteQubits to manipulate the representation of quantum states and possibly reduce the overhead from MPI communication
class ChiMatrix to represent quantum channels and method ApplyChannel to simulate 1- and 2-qubit channels
extra examples and tutorials
ReadTheDocs for easy-to-navigate documentation

Changed

CMake build is now modular
the library is part of namespace iqs

Removed

Fixed

when compiling with GCC, the option -O3 is used for performance improvement
a few minor bugs
update examples to current syntax

[ 2.0.0 ] - [ 2019-12-12 ]

Added

pool of state functionality: parallel execution of multiple circuits
Python bindings based on PyBind11 (no MPI)
tutorials and a few new examples
methods to simulate with noise and decoherence within QubitRegister class
benchmarks to reproduce weak and strong scaling of 1-qubit gate runtime
methods specialized for emulation of QAOA circuits

Changed

building process based on CMake instead of Make
main class name changed from QbitRegister to QubitRegister
MPI environment extended to support the "pool of state" functionality
examples updated to new syntax and methods

Removed

Fixed

Added

implementation of customized MPI environment
implementation of QbitRegister class for simulation of quantum circuits
methods to simulate 1-qubit gates and controlled-1-qubit gates, state preparation and measurement
