A Physical Qubit with built-in Error Correction

The creation of a photonic “Schrödinger cat state” – in other words the quantum superposition of states of the laser pulse amplitude that can be distinguished on a macroscopic scale (white or black cat) – can only be achieved using the most advanced quantum optical techniques and has already been demonstrated to be possible. In the present experiment that is subject of the research paper, it proved to be feasible to extend this to three states (white, gray, and black cats). This light state thus approaches a logical quantum state in which errors can be, in principle, universally corrected. (ill./ ©: Peter van Loock)
