Qotlin

This is a Kotlin library for developing, deploying and running quantum assembler (QASM) programs on quantum computers available in IBM Q Experience program.

See below to get a taste:

object Main {
    @JvmStatic
    fun main(args: Array<String>) {
        val qex = Qotlin()

        qex.login("YOUR_API_TOKEN_HERE")

        qex.enumerateDevices()

        println("Currently available:")
        qex.devices.forEach {
            println(it)
        }

        println("\nRunning Bell state experiment")
        qex.simulator
                .submitJob(256, 1, qasm {
                    qreg(2)
                    creg(5)
                    h(0)
                    cx(0, 1)
                    measure(0, 1)
