The black paper of quantum cryptography: real implementation problems
Valerio Scarani, Christian Kurtsiefer
The laws of physics play a crucial role in the security of quantum key distribution (QKD). This fact has often been misunderstood as if the security of QKD would be based only on t…
Updating Quantum Cryptography Report ver. 1
Donna Dodson, Mikio Fujiwara, Philippe Grangier +24
Quantum cryptographic technology (QCT) is expected to be a fundamental technology for realizing long-term information security even against as-yet-unknown future technologies. More…
Eliminating Spectral Distinguishability in Ultrafast Spontaneous Parametric Down-conversion
Hou Shun Poh, Jiaqing Lim, Ivan Marcikic +2
Generation of polarization-entangled photon pairs with a precise timing through down-conversion of femtosecond pulses is often faced with a degraded polarization entanglement quali…
Phase shift of a weak coherent beam induced by a single atom
Syed Abdullah Aljunid, Meng Khoon Tey, Brenda Chng +4
We report on a direct measurement of a phase shift on a weak coherent beam by a single Rb-87 atom in a Mach-Zehnder interferometer. A maximum phase shift of about 1 degree is obser…
Clock synchronization by remote detection of correlated photon pairs
Caleb Ho, Antia Lamas-Linares, Christian Kurtsiefer
We present an algorithm to detect the time and frequency difference of independent clocks based on observation of time-correlated photon pairs. This enables remote coincidence iden…
