Release 0.7.0: Feature release

Added

• support for single qubit flux options (auto/manual modes)
• option to control generation of qasm files and dot graphs
• NPROCS=n variable can now be set for faster compilation to use n threads
• conda build recipe
• conda binary releases for Linux, Windows platform (not yet available for OSX due to a conda distribution issue)

Changed

• openql is now public
• improved resource-constrained scheduling
• sweep point array is now optional
• support for barrier/wait on all qubits

Removed

• set_sweep_points(sweep_points list, num of sweep points)

Fixed

• resource-constrained qasm is generated by same scheduler for cc-light as is used to generate qisa
• Illegal parameter in gate_decomposition

Release 0.6.0: cQASM v1.0 support and other enhancements

Added

• generated qasm code conforms to cQASM v1.0 specification
• added libqasm to pytest to test conformance of generated qasm

Changed

• ALAP scheduler is the default option (Issue #193)
• compiling an empty program raises error (Issue #164)

Removed

Fixed

• tests are added to test option setting/getting (Issue #190)

Fixed stateful behavior and and instruction ordering

[ 0.5.5 ] - [ 2018-10-25 ]

Added

Changed

• simplified interface of Program.set_sweep_points (Issue #184)

Removed

Fixed

• instruction ordering to generate consistent qisa (Issue #190)
• stateful behaviour in OpenQL (Issue #171)

Fixed qubit operand ordering in SMIS and SMIT instructions

This solves the problem raised in issue #190.

The solution is also an optimization in the sense that previously 3 SMIS instructions were generated for the qubit operands 2,3 and 4 as:

smis s10, {2, 3, 4}
smis s11, {3, 2, 4}
smis s12, {4, 3, 4}

This also means three registers were used. With this solution, operands are ordered and a single SMIS instruction is generated to use a single register. The same explanation applies to 2 operand instructions.

Fixed ALAP scheduling and updated resource manager for cc light

Added

• added detuning constraints for cclight

Changed

Removed

Fixed

• alap scheduling for cclight

• getting started example (getting_started.py)

High level compiler features

Added

• kernel conjugation/un-compute feature
• multi-qubit control decomposition
• toffoli decomposition
• QASM loader for cQASM v1.0 syntax check
• initial support for Quantumsim backend
• vebosity levels

Changed

• program options can be set/get with simple api calls
• when adding gates, qubits should always be specified as list
• updated qisa-as support for tests

Removed

• qisa-as is not a part of openql
• prog.compile() does not get optimiz/schedule/verbose options

Fixed

• static iteration count for scheduled qasm
• roation angle printing
