Filed:

Feb 19, 2021

Appl. No.:

17/179490

Inventors:

- MELBOURNE FL, US
MICHAEL R. LANGE - MELBOURNE FL, US
JAMES A. NAGEL - FORT WAYNE IN, US

International Classification:

H04B 10/70
H04B 10/61
H04B 10/508

Abstract:

A quantum communications system may include transmitter node, a receiver node, and a quantum communications channel coupling the transmitter node and receiver node. The transmitter node may be configured to co-propagate a first pulse for a quantum state and a second pulse to stabilize the quantum state through the quantum communications channel.

Abstract:

A quantum communications system may include a transmitter node, a receiver node, and a quantum communications channel coupling the transmitter node and receiver node. The receiver node may be configured to arrange a received bit stream of optical pulses from the transmitter node into time bins, convert the optical pulses in the time bins into corresponding optical pulses in frequency bins, and detect respective optical pulse values from each of the frequency bins.
