Qdot

This project is new and under initial development. Qdot is a Scala 3 library (QASM-transpiler) that allows Scala/Java developers write native quantum/hybrid programs.

Motivations

  1. Run hybrid programs on JVM directly, by sending transpiled QASM to quantum computers directly through IBM qiskit python. Currnet impl include: quantum Fourier transform/phase estimation, QAOA.

  2. Leverage Scala syntax + type system for concise and correct programs.

  3. Compile-time checks - which becomes particularly important as size of hybrid programs increases. To be implemented with Scala3 macros.

For any question please ask in #qdot channel in http://discord.unitary.fund/

sbt project compiled with Scala 3

Usage

This is a normal sbt project. You can compile code with sbt compile, run it with sbt run, and sbt console will start a Scala 3 REPL.

For more information on the sbt-dotty plugin, see the scala3-example-project.

To run written quantum programs on IBMQ, you will need to have Python and Qiskit install Install qiskit with pip install qiskit, use a new separate environment if you wish (e.g conda create -n ENV_NAME python=3 and conda activate ENV_NAME) You need to provide you IBMQ api token to scala.qdot.backend.IBMQBackend class.
