In their efforts to observe quantum phenomena on a macroscopic scale, researchers in Denmark managed to create a network of 30,000 entangled pulses of light arranged in a two-dimensional lattice distributed in space and time. They produced light beams with special quantum mechanical properties (squeezed states) and woven them together using optical fibre components to form a cluster state. An optical quantum computer will therefore not require costly and advanced refrigeration technology, its information-carrying light-based qubits in the laser light will be much more durable and it can be more easily be scaled to contain hundreds of qubits…read more.
