use it as the default ProjectQ simulator by simply building and installing ProjectQ with the `--with-qracksimulator` global option. This exchanges the Qrack simulator for the default ProjectQ C++ simulator, throughout. Any application which would rely on the default C++ simulator should then automatically use the Qrack simulator instead. -Note that Qrack does not (yet) support time evolution, or nonunitary operations available in the default C++ simulator. Unsupported operations are `QubitOperator` and expectation value and time evolution calculation by the direct simulator methods. To keep integer math unitary, the integer multiplication operation uses the more significant half of the multiplication operation register as a "carry" sub-register, which is measured and then zeroed at the beginning of a multiplication operation. +Note that Qrack does not support any nonunitary operations available in the default C++ simulator.

The new variant just uses its matrix representation to run it in native code. * C++ simulator performance: add dedicated C++ code for common math gates The BasicMathGate uses a C++ python wrapper (emulate_math_wrapper) to allow generic calculations which makes it very slow. This detects some math gates and provides a native C++ implementation for it. * C++ simulator performance: use larger memory alignment * C++ simulator performance: recycle large StateVector memory buffers This avoids costly std::vector copying/reallocations by using some static std::vector to reuse the allocated buffer (just by std::swap'ing a vector into a buffer for later use when it would be deallocated otherwise). * C++ simulator performance: improve compiler flags * Add test coverage for constant math emulation * Revert "Add test coverage for constant math emulation" This reverts commit 3bb8a2cc7fd595db48b0f4d260124ccfe60d7fcf. * Add test coverage for constant math emulation * Update constant math documentation to include list of pre-conditions (#331) * Removing -ffast-math option * Partial fix/skip for amplitude amplification --- docs/projectq.ops.rst | 1 + docs/projectq.setups.decompositions.rst | 8 + projectq/backends/_resource_test.py | 5 +- .../backends/_sim/_cppkernels/simulator.hpp | 154 +++++++++++---- projectq/backends/_sim/_cppsim.cpp | 3 + projectq/backends/_sim/_simulator.py | 28 ++- projectq/backends/_sim/_simulator_test.py | 52 +++++ projectq/libs/math/_gates.py | 25 +++ projectq/ops/__init__.py | 1 + projectq/ops/_gates.py | 51 ++++- projectq/ops/_gates_test.py | 36 ++++ projectq/ops/_qaagate.py | 81 ++++++++ projectq/ops/_qaagate_test.py | 27 +++ projectq/setups/decompositions/__init__.py | 6 +- .../decompositions/amplitudeamplification.py | 111 +++++++++++ .../amplitudeamplification_test.py | 183 ++++++++++++++++++ .../decompositions/phaseestimation_test.py | 59 +++--- setup.py | 2 + 18 files changed, 750 insertions(+), 83 deletions(-) create mode 100755 projectq/ops/_qaagate.py create mode 100755 projectq/ops/_qaagate_test.py create mode 100644 projectq/setups/decompositions/amplitudeamplification.py create mode 100644 projectq/setups/decompositions/amplitudeamplification_test.py diff --git a/docs/projectq.ops.rst b/docs/projectq.ops.rst index 58d66ee16..6b9ec5936 100755 --- a/docs/projectq.ops.rst +++ b/docs/projectq.ops.rst @@ -55,6 +55,7 @@ The operations collection consists of various default gates and is a work-in-pro projectq.ops.StatePreparation projectq.ops.QPE projectq.ops.FlipBits + projectq.ops.QAA Module contents diff --git a/docs/projectq.setups.decompositions.rst b/docs/projectq.setups.decompositions.rst index d900f5bfc..26cd392fc 100755 --- a/docs/projectq.setups.decompositions.rst +++ b/docs/projectq.setups.decompositions.rst @@ -27,6 +27,7 @@ The decomposition package is a collection of gate decomposition / replacement ru projectq.setups.decompositions.toffoli2cnotandtgate projectq.setups.decompositions.uniformlycontrolledr2cnot projectq.setups.decompositions.phaseestimation + projectq.setups.decompositions.amplitudeamplification Submodules @@ -180,6 +181,13 @@ projectq.setups.decompositions.phaseestimation module :members: :undoc-members: +projectq.setups.decompositions.amplitudeamplification module +--------------------------------------------------------------- + +.. automodule:: projectq.setups.decompositions.amplitudeamplification + :members: + :undoc-members: + Module contents --------------- diff --git a/projectq/backends/_resource_test.py b/projectq/backends/_resource_test.py index 664b687ad..cf7122c01 100755 --- a/projectq/backends/_resource_test.py +++ b/projectq/backends/_resource_test.py @@ -20,7 +20,7 @@ from projectq.cengines import DummyEngine, MainEngine, NotYetMeasuredError from projectq.meta import LogicalQubitIDTag -from projectq.ops import All, Allocate, CNOT, Command, H, Measure, QFT, Rz, X +from projectq.ops import All, Allocate, CNOT, Command, H, Measure, QFT, Rz, Rzz, X from projectq.types import WeakQubitRef from projectq.backends import ResourceCounter @@ -74,6 +74,7 @@ def test_resource_counter(): CNOT | (qubit1, qubit3) Rz(0.1) | qubit1 Rz(0.3) | qubit1 + Rzz(0.5) | qubit1 All(Measure) | qubit1 + qubit3 @@ -81,7 +82,7 @@ def test_resource_counter(): int(qubit1) assert resource_counter.max_width == 2 -

This detects some math gates and provides a native C++ implementation for it. * C++ simulator performance: use larger memory alignment * C++ simulator performance: recycle large StateVector memory buffers This avoids costly std::vector copying/reallocations by using some static std::vector to reuse the allocated buffer (just by std::swap'ing a vector into a buffer for later use when it would be deallocated otherwise). * C++ simulator performance: improve compiler flags * Add test coverage for constant math emulation * Revert "Add test coverage for constant math emulation" This reverts commit 3bb8a2cc7fd595db48b0f4d260124ccfe60d7fcf. * Add test coverage for constant math emulation * Update constant math documentation to include list of pre-conditions (#331) * Allow selection of drawing order in CircuitDrawer (solves #333) (#334) * included the possibility to draw the gates in the order they were added to the circuit * edited param names tests should pass now * solved comments * solved comments * passes tests * Test for unordered and ordered circuit drawing * Reindent files in _circuits * Minor adjustments to _drawer.py * added test_body_with_drawing_order * fixed tests and how draw_gates_in_parallel is interpreted * Fix failing tests with Python 2.7 One test of _to_latex_test.py was failing due to precision issues. * Trapped ion decomposer setup and rotation gates improvement (#346) * reduced Ry decomposition : modification of restrictedgateset setup to include compiler chooser, extension of available decompositions, new setup based on restrictedgateset but adapted for trapped ion configurations * Addition of test file for the rz2rx decomposition Addition of test file for the rz2rx decomposition and edit to comments in the rz2rx file * Revert "Addition of test file for the rz2rx decomposition" This reverts commit 5aab56b7384d60d5ac09e5b08bebf14135b5a006. * Create rz2rx_test file Addition of test file for the rz2rx decomposition * Update rz2rx.py Update to comments * Update rz2rx_test.py Update to comments * Minor update: remove accidental file * Minor update rz2rx.py Corrected an angle. * Minor update rz2rx_test.py Edited comments. * Create h2rx_test.py Updated method for test_decomposition which tests that decomposition produces identical wave-state up to a global phase. * Improvement of the decomposition chooser; Note that basic restricted gate set will fail decomposing into Rxx because of the default chooser * Updates to h2rx and cnot2rxx * Create cnot2rxx_test.py Testing file for cnot2rxx decomposition.
