Sample Program (Deutsch's Algorithm)

Deutsch's algorithm can be used to tell in a single pass whether a function is constant or balanced.

// A function is sequence of parallel gates

funq blackbox =
    I I         // These are both identity gates - they do nothing
    CNOT        // This gate is a CNOT - it is two qubits wide

// A let definition is starting state, which can
// be followed by a sequence of parallel gates.
let deutsch =
    0 1             // These are the initial starting states
    H H

    log "before"    // You can debug intermediate states in a 'let' expression
    blackbox
    log "after"

    H H

let main =
