Feng Lab’s hyperdimensional microlaser generates “qudits”. Click for info.
With only two levels of superposition, the qubits used in today’s quantum communication technologies have limited storage space and low tolerance for interference. The Feng Lab’s hyperdimensional microlaser (above) generates qudits, photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications.
