Secure Channel Demo | Turn lessons into working experiments

Starter code

module secure_channel_demo;

fn main() {
  let q = qreg[1];
  H(q[0]);
  let measured: Bit = measure(q[0]);
  return measured;
}

Expected output

A superposition is prepared

Measurement collapses to a classical result

Repeated runs show sampling behavior

Run the circuit several times

Record observed outcomes

Explain why observation matters

Write a channel trust note

Add a second qubit and describe how a shared-check protocol might use it.
