Alice and Bob have shared two entangled qubits, which they use to transfer data between them using what appears to be similar to superdense coding (but without sending any qubits). Given only Alice’s operations on her own qubit, can we reconstruct what she send to Bob? Can we, or can we not? You won’t know until you collapse the state of this write-up. ;)
