Powerful Simulator

Scotty comes with a quantum circuit simulator for up to 29 qubits.

Quantum Circuits

Build quantum circuits with custom and composite gates.

State Tools

Explore qubit superpositions and collapsed classical states.

Quantum Experiments

Here's a fully working example of a quantum teleportation algorithm implemented with Scotty:

def entangle(q1: Int, q2: Int) = Circuit(H(q1), CNOT(q1, q2))

val msg = Qubit(Complex(0.8), Complex(0.6), "message")
val here = Qubit.zero("here")
val there = Qubit.zero("there")

val register = QubitRegister(msg, here, there)

val circuit = entangle(1, 2)
  .combine(CNOT(0, 1), H(0))
  .combine(CNOT(1, 2), Controlled(0, Z(2)))
  .withRegister(register)

implicit val sim = QuantumSimulator()

assert(
  QubitProbabilityReader(register, sim.run(circuit))
    .read("there")
    .fold(false)(_.probabilityOfOne ~= msg.probabilityOfOne))
