History of Development
| Date | Developments | Notes |
|---|---|---|
| Oct 23rd 2003 | DARPA Quantum Network becomes fully operational | The world’s first quantum encrypted functional network becomes fully operational in BBN Labs |
| June 2004 | DARPA Quantum Network is linked between campuses | Dark fibre routed beneath the streets of Cambridge, Massachusetts - used to link Harvard University with the BBN Technologies campus, allowing non-stop quantum cryptography 24/7 |
| Dec 2004 | Quantum Network consists of 6 nodes. | Four (nodes) are 5 MHz, BBN-built BB84 systems designed for telecommunications fiber and inter-connected by a photonic switch. Two are the electronics subsystems for a high speed free-space system designed and built by NIST. |
| June 2005 | DARPA Quantum Network expands to incorporate first free-space link | Allowing quantum keys and communications to be transmitted securely through the air |

Famous quotes containing the words history of, history and/or development:
“If usually the “present age” is no very long time, still, at our pleasure, or in the service of some such unity of meaning as the history of civilization, or the study of geology, may suggest, we may conceive the present as extending over many centuries, or over a hundred thousand years.”
—Josiah Royce (1855–1916)
“[Men say:] “Don’t you know that we are your natural protectors?” But what is a woman afraid of on a lonely road after dark? The bears and wolves are all gone; there is nothing to be afraid of now but our natural protectors.”
—Frances A. Griffin, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 19, by Susan B. Anthony and Ida Husted Harper (1902)
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
