Quantum computing using chiral qubits

This invention describes a quantum computer that uses tiny rings, less than a micron across, made from special materials like Dirac or Weyl semimetals. These rings act as qubits, holding quantum information in two stable states. A terahertz cavity detects these states, and circularly polarized light is used to excite a special "chiral current" within the rings, which then determines their quantum states. The claims specifically narrow the materials to a list including zirconium pentatelluride.
