1. A computer-implemented method comprising:
encoding, by a sender party, quantum information into an information qubit;
encrypting, by the sender party, the information qubit, comprising performing i) a parity operation on the information qubit and a parity control qubit and a phase operation on the information qubit and a phase control qubit, and ii) performing a predetermined sequence of one or more quantum logic gates on the phase control qubit;
sending, by the sender party, the encrypted information qubit to a recipient party, wherein the recipient party performs one or more operations on the encrypted information qubit;
receiving, by the sender party and from the recipient party, the encrypted information qubit; and
decrypting, by the sender party, the encrypted information qubit received from the recipient party.
