Stanford Engineers Propose a Simpler Design for Quantum Computers

On the left is the storage ring, which holds several counter-propagating photons. On the right is the scattering unit, which is used to manipulate the photonic qubits. The spheres at the top, called “Bloch spheres,” depict the mathematical state of the atom and one of the photons. Because the atom and the photon are entangled, manipulating the atom also affects the state of the photon. Credit: Ben Bartlett
