Quantum cryptography with polarization, phase and time encoding
W. T. Buttler, S. K. Lamoreaux
We develop and present a quantum cryptography concept in which phase determinations are made from the time that a photon is detected, as opposed to where the photon is detected, an…
Thermal noise limitations to force measurements with torsion pendulums: Applications to the measurement of the Casimir force and its thermal correction
S. K. Lamoreaux, W. T. Buttler
A general analysis of thermal noise in torsion pendulums is presented. The specific case where the torsion angle is kept fixed by electronic feedback is analyzed. This analysis is…
New, efficient and robust, fiber-based quantum key distribution schemes
William T. Buttler, Justin R. Torgerson, Steven K. Lamoreaux
We present a new fiber based quantum key distribution (QKD) scheme which can be regarded as a modification of an idea proposed by Inoue, Waks and Yamamoto (IWY) [1]. The scheme des…
Daylight quantum key distribution over 1.6 km
W. T. Buttler, R. J. Hughes, S. K. Lamoreaux +3
Quantum key distribution (QKD) has been demonstrated over a point-to-point -km atmospheric optical path in full daylight. This record transmission distance brings QKD a st…
Practical quantum cryptography for secure free-space communications
Richard J. Hughes, William T. Buttler, Paul G. Kwiat +4
Quantum cryptography is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states o…
Practical free-space quantum key distribution over 1 km
W. T. Buttler, R. J. Hughes, P. G. Kwiat +6
A working free-space quantum key distribution (QKD) system has been developed and tested over an outdoor optical path of ~1 km at Los Alamos National Laboratory under nighttime con…
