v1.15.0

Bugfixes

Improvements

• Write unit test for EXP-PAULI (@jmbr, #496).
• Add DIRECTION as frame attribute (@kilimanjaro, #499).
• Use SAFELY-PARSE-QUIL on external input (@notmgsk, #500).

v1.14.0

Changelog

Bugfixes

• Fix type checking for classical-equality instructions (@notmgsk, #492).
• Don't call APPLICATION-ARGUMENTS on potential non-application instr (@appleby, #490).
• Error if preserved block touches illegal qubits (@notmgsk, #489).
• Fix parametric RZ agglutination (@notmgsk, #480).

Improvements

• Add symbolic compilers for forked/controlled/daggered rotations (@ecpeterson, #484).
• Improve compiler patience (@ecpeterson, #483).
• Asynchronously check for version update (@stylewarning, #478).

v1.13.1

Changelog

This version bump is prompted by the various issues we have run in to by distributing the tweedledum shared library. This PR temporarily disables tweedledum support so that the various SDK packages are supported on all the claimed OS's.

Bugfixes

• Temporarily disable tweedledum (@notmgsk, #475).
• Include RESET-QUBIT and MEASURE in PROG-INITIAL-REWIRING-HEURISTIC (@appleby, #474).

Features / Improvements

Behind-the-scenes

• Export with-inst (@stylewarning, #472).

v1.13.0

Changelog

Features

• XY synonym for PISWAP (@ecpeterson, #469).
• Wildcard ISA (@ecpeterson, #470).
• Version check at start-up (@notmgsk, #462).

Bugfixes

• Use "quilc" rather than argv[0] for syslog name (@notmgsk, #466).

Behind-the-scenes

• Use the new SDK version listing (@notmgsk, #467).
• Consistently capitalize control characters (@appleby, #455).
• Fix docstring typos for UPDATE-PRINT-PARSED-PROGRAM-GOLDEN-FILES (@appleby, #453).
• Add periods to sentences without periods (@kilimanjaro, #452).
• Prefer format string for printing AST objects (@kilimanjaro, #450).
• Refactor and improve documentation around ISA (@notmgsk, #442).

v1.12.1

Patch release that removes the use of "testing" apt repos from the install-test-deps Makefile target, which has the effect of downgrading glibc from 2.29 to 2.28.

v1.12.0

In addition to various internal code-cleanliness changes, v1.12.0 contains the following changes:

• The state transformation routines have been upgraded: we implemented a more efficient decomposition for four-qubit state preparation, and we replaced the numerical approximation for manufacturing short two-qubit state-to-state transformations with an exact routine.
• The parser for the STORE instruction incorrectly rejected certain legal Quil instructions. This bug has been fixed.
• There is a new transform pass which simplifies affine-linear expressions appearing in gate parameters.

v1.11.1

This is a patch release on top of v1.11.1 in order to include RPCQ v2.7.3 in the automatically generated docker image.

v1.11.0

This release consists primarily of bugfixes and internal reorganization.

v1.10.4

Bugfixes:

• Use appropriate arithmetic routines in compilers #365 @notmgsk @ecpeterson

v1.10.3

Bug fixes:

• Allow unordered keys in ISA dictionary (#362) and warn against such (#364)
