Science Daily  October 17, 2019 The approach taken by an international team of researchers (Japan, Australia, USA – University of New Mexico) starts with extreme scalability, built in from the very beginning, because the processor, called a cluster state is made of light. A cluster state is a large collection of entangled quantum components that performs quantum computations when measured in a particular way. To be useful for real-world problems, a cluster state must be both large enough and have the right entanglement structure. To make the cluster state, specially designed crystals convert ordinary laser light into quantum light called […]
