Notable Changes

New QuantumArithmetic library

This release is the first to add the QuantumArithmetic library by @fedimser to the list of suggested libraries! Check out more about the library at https://github.com/fedimser/quant-arith-re.

Measurement and qubit reuse decompositions handled in QIR generation

This change addresses a long-standing point of confusion regarding how programs compiled for QIR Base profile are displayed in places like the circuit visualizer. By delaying application of decompositions for deferred measurement and avoidance of qubit reuse to the QIR generation step, the stdlib implementation of measurement no longer needs to have a different implementation for Base profile vs other profiles. This should make the displayed circuits match the written code more often. See #2230 for more details.

v1.13

We are excited to release v1.13 of the Azure Quantum Development Kit! Here are some highlights of features included in this month's release:

@Test Attribute and VS Code Test Explorer Integration

#2095 Introduced a new attribute, @Test, which identifies unit tests written in Q#. By integrating with the Text Explorer feature in VS Code, you can now explore, run, and review Q# unit test execution:
image
See the wiki page on Testing Q# Code in VS Code for more information.

"Q#: Add Project Reference" VS Code Command Enhancements

#2079 enhanced the VS Code command for adding references to a Q# project, available when editing a qsharp.json file:
image
When invoking the command, you'll now see a choice to either import from GitHub or search the currently opened workspace for other Q# projects. When choosing GitHub, you'll get a suggestion of known libraries and their available versions to choose from, and the corresponding external project reference snippet will automatically be added to your current qsharp.json:

More Python Interoperability for Callables

#2091 added more support for using Python functions that wrap Q# callables across our Python package APIs. This makes it easier to pass Python arguments into Q# for features like resource estimation with qsharp.estimate(), running multiple shots with qsharp.run(), compiling to QIR with qsharp.compile(), or generating circuits with qsharp.circuit():
image
For more information on using Q# callables directly in Python, see the Invoking Q# Callables from Python wiki page.

Adaptive Profile Floating-Point Computation Extension

#2078 added support for an additional QIR Adaptive profile extension: floating-point computation. By choosing QIR Adaptive RIF as your compilation profile, you can enable Reset, Integer computation, and Floating-point computation for code generation. This allows you to write programs where the values of variables with Q# type Double can be dyanmically calculated from measurement results at runtime, and the output QIR will include arithmetic and comparison instructions corresponding to your code, enabling even more adaptive algorithms.
image

Note that this profile extension must be supported by the target backend or runtime environment for the resulting code to execute. See the QIR specification section on Classical Computation extensions to the Adaptive profile for more details.

v1.12

We are excited to release v1.12 of the Azure Quantum Development Kit! Here are some highlights of features included in this month's release:

Python interoperability improvements

You can now import and invoke your Q# callables for simulation directly from Python as functions. Your callables defined in %%qsharp magic cells, through calls to qsharp.eval, or loaded from projects in qsharp.init can now be imported from the qsharp.code module:

import qsharp

qsharp.eval("""
    operation Superposition() : Result {
        use q = Qubit();
        H(q);
        Std.Diagnostics.DumpMachine();
        MResetZ(q)
    }
    """)

from qsharp.code import Superposition
result = Superposition()

For more details and current limitations, see Invoking Q# callables from Python in the wiki.

Syntax for capturing state dumps from DumpMachine or DumpRegister and operation matrices from DumpOperation calls in your Q# code has also been improved (see #2042)

Deprecation of set keyword

The set keyword used for updating mutable values is now deprecated, so where you previously had to use set x += 1 you can now just write x += 1. In addition, the compiler includes a new lint that defaults to "allow" that you can use to warn or error on usage of set in your code (see #2062).

ApplyUnitary operation for simulation

When running against the simulator, your Q# code can call ApplyUnitary and pass a unitary matrix represented by a Std.Math.Complex[][] along with an array of qubit targets and have the simulator directly apply that unitary to the current sparse state vector.

Increase minimum versions for Python and Ubuntu

Starting with v1.12, the minimum supported Python version for the qsharp package is Python 3.9. Along with this change, the minimum compatible version of Ubuntu has been increased to 22.04 (see #2061)

v1.11.1

We are excited to release v1.11.1 of the Azure Quantum Development Kit! This month's release includes features and bug fixes, such as:

Configure Pauli Noise Dynamically within Q#

You can now use the ConfigurePauliNoise function to dynamically update noise settings during simulation, allowing samples, exercises, or test code to directly set noise used in testing (#1997).

Stabilization of the Microsoft.Quantum.Unstable libraries

The Arithmetic, StatePreparation, and TableLookup libraries have been stabilized and are now available under Std. Several samples and libraries have been updated to reflect the new location, while the Microsoft.Quantum.Unstable namespace will be preserved for backward compatibility (#2022, #2043).

Support for Qiskit v1.3.0

Changes made to the Qiskit target class in v1.3.0 that broke interoperability with the qsharp Python package are now handled dynamically allowing use of both v1.2 and v1.3 versions of Qiskit (#2050).

v1.10.1

We are excited to release v1.10 of the Azure Quantum Development Kit! This month's release includes several new features and improvements including:

Code editing improvements

Code editing is now greatly improved. A couple of examples of the many improvements:

  • Context aware completions (#1947) show only the relevant completions for the location. For example, only showing types when in a type position:

    image

  • Namespace member (#1947) completion lists are now provided when drilling into namespaces:

    image

  • User Defined Type (#1954) member completions are now populated

    image

And much more! Parser error recovery has also been greatly improved so that editor assistance is available whilst mid-edit in many more scenarios.

Noisy simulation

You can now add Pauli noise to simulations run from Python or VS Code (#1971, #1975, #1980). This can help model the results of running on a real quantum machine for education purposes, and to help develop and test the effectiveness of error correction.

Below shows the results of configuring 5% bit-flip noise in VS Code and running a histogram on the GHZ sample. This would return only $\ket{000}$ and $\ket{111}$ shot results if run in a noise free simulation.

image

To see how to use noisy simulation in Python, check out the sample notebook at https://github.com/microsoft/qsharp/blob/main/samples/notebooks/noise.ipynb

Refreshed API docs interface

The in-editor Q# API documentation has had a UI refresh (#1978). This is accessed via the "Q#: Show API documentation" command in the command palette when editing a Q# file. The new UX allows you to quickly & easily search & navigate the APIs within your project, referenced projects, and the standard library.

image

File icons

The Q# file extension (.qs) now gets a unique icon in VS Code (#1976)

image

Custom measurements and resets

Previously you could define custom gates, but not custom measurement or reset operations. With #1967, #1981, and #1985 this is now possible. This allows for the definition and use of custom operations for quantum simulation and QIR code generation.

Samples for this feature will be added shortly, in the meantime see the test code at https://github.com/microsoft/qsharp/blob/v1.10.1/compiler/qsc/src/codegen/tests.rs#L529 for an example of how this may be used.

Python telemetry

In this release we have added telemetry to our qsharp Python package to collect minimal and anonymous metrics on feature usage and performance. This will allow us to focus our investments going forward on the most valuable areas. Please see the notes in the package readme for details on what is collected and how to disable it.

v1.9.0

The 1.9.0 release of the QDK includes interoperability with Qiskit circuits built upon the core Q# compiler infrastructure.

The Qiskit interop provided by the QDK includes:

The Qiskit interop wiki page provides a brief overview of the integration while detailed examples, potential errors, and usage with parameterized circuits are demonstrated in the sample Qiskit interop notebook.

In addition to the Qiskit interop feature, the language service for Q# will now auto-suggest the new standard library API instead of the legacy Microsoft.Quantum-prefixed standard library API. For example, when typing DumpMachine, you'll now get a suggested import for Std.Diagnostics.DumpMachine instead of Microsoft.Quantum.Diagnostics.DumpMachine.
