Controlling passively-quenched single photon detectors by bright light
Vadim Makarov
Single photon detectors based on passively-quenched avalanche photodiodes can be temporarily blinded by relatively bright light, of intensity less than a nanowatt. I describe a bri…
On the Feigel Effect: Extraction of Momentum from Vacuum?
Ole Jakob Birkeland, Iver Brevik
The Green-function formalism for the electromagnetic field in a magnetoelectric (ME) medium is constructed, as a generalization of conventional Casimir theory. Zero temperature is…
Spontaneous Emission Near Superconducting Bodies
Bo-Sture K. Skagerstam, Per Kristian Rekdal
In the present paper we study the spontaneous photon emission due to a magnetic spin-flip transition of a two-level atom in the vicinity of a dielectric body like a normal conducti…
Extreme points of the set of density matrices with positive partial transpose
Jon Magne Leinaas, Jan Myrheim, Eirik Ovrum
We present a necessary and sufficient condition for a finite dimensional density matrix to be an extreme point of the convex set of density matrices with positive partial transpose…
Quantum synapse for cold atoms
G. A. Kouzaev, K. J. Sand
In this paper, the quantum synaptic effect is studied that arisen in the system of two crossed wires excited by the static (DC) and radio-frequency (RF) currents. The potential bar…
Faked states attack using detector efficiency mismatch on SARG04, phase-time, DPSK, and Ekert protocols
Vadim Makarov, Johannes Skaar
In quantum cryptosystems, variations in detector efficiency can be exploited to stage a successful attack. This happens when the efficiencies of Bob's two detectors are different f…
