Constructing 2D and 3D cluster states with photonic modules

Understand

Large scale quantum information processing (QIP) and distributed quantum computation require the ability to perform entangling operations on a large number of qubits.

• We describe a new photonic module which prepares, deterministically, photonic cluster states using an atom in a cavity as an ancilla.
• Based on this module we design a network for constructing 2D cluster states and then we extend the architecture to 3D topological cluster states.
• Advantages of our design include a passive switching mechanism and the possibility of using global control pulses for the atoms in the cavity.
