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:
“This is the greatest week in the history of the world since the Creation, because as a result of what happened in this week, the world is bigger, infinitely.”
—Richard M. Nixon (1913–1995)
“When the landscape buckles and jerks around, when a dust column of debris rises from the collapse of a block of buildings on bodies that could have been your own, when the staves of history fall awry and the barrel of time bursts apart, some turn to prayer, some to poetry: words in the memory, a stained book carried close to the body, the notebook scribbled by hand—a center of gravity.”
—Adrienne Rich (b. 1929)
“A defective voice will always preclude an artist from achieving the complete development of his art, however intelligent he may be.... The voice is an instrument which the artist must learn to use with suppleness and sureness, as if it were a limb.”
—Sarah Bernhardt (1845–1923)
