image: The image shows photonic qubits, which allow remote quantum computing to be performed on a server. Input qubits enter from the left with a state known only to the user. Qubits become entangled in the center during the computation. The clouding represents the quantum computer's inability to interpret the data, its "blindness." On the right, the results are well defined qubits that are delivered back to the user. This image relates to a paper that appeared in the Jan. 20, 2012, issue of Science, published by AAAS. The paper, by S. Barz at Austrian Academy of Sciences in Vienna, Austria, and colleagues was titled, “Demonstration of Blind Quantum Computing.” view more
