Scientists have long dreamed of building a quantum computer capable of processing enormous amounts of data and solving complex problems at ultra-high speeds. Now a team of Yale engineers has taken a major step forward by building the world's first solid-state, two-qubit quantum processor capable of running simple algorithms. Steven Girvin, Yale's Eugene Higgins Professor of Physics and Applied Physics, explains the design, what the processor is capable of doing, and the promise that quantum computing holds for the future.
