Quantum Computing Using Linear Optics
... Our goal was to design LOQC logic devices that are as simple, stable, and as robust as possible. We therefore used qubits represented by the polarization states of single photons, as illustrated in Fig. 1a. Polarizationencoded qubits are more resistant to certain kinds of experimental errors and eas ...
