1. A system for noise-resistant quantum communication, the system comprising:
a quantum system including a plurality of qubits;
a processor; and
a memory, including instructions stored thereon, which, when executed by the processor, cause the quantum system to:
access a signal of a quantum system;
perform hyperentanglement of the plurality of qubits via an entanglement source, wherein the hyperentanglement of the plurality of qubits is in at least two dimensions, and wherein the at least two dimensions include a first dimension and a second dimension;
transmit the hyperentangled plurality of qubits via a communication channel;
obtaining a communication of the signal with the first dimension of the at least two dimensions; and
filter results of the communicated signal based on the second dimension of the at least two dimensions.
