"enable much smaller and cheaper error-free quantum computers... qubit intrinsic redundancy instead of more of them... superconducting cavity qubit with microwave radiative photons trapped inside, with information encoded multimode into their quantum states, where several of photon’s properties used at once storing information, enhancing qubit resiliency... computers up to 50X smaller, consuming 10X less power... future:, manipulating information stored within qubits during calculations, with >100 qubits by 2029"
