Large-alphabet quantum key distribution using energy-time entangled bipartite States.
We present a protocol for large-alphabet quantum key distribution (QKD) using energy-time entangled biphotons. Binned, high-resolution timing measurements are used to generate a large-alphabet key with over 10 bits of information per photon pair, albeit with large noise. QKD with 5% bit error rate is demonstrated with 4 bits of information per photon pair, where the security of the quantum chan...
متن کاملQuantum Time-Frequency Transforms
Time-frequency transforms represent a signal as a mixture of its time domain representation and its frequency domain representation. We present efficient algorithms for the quantum Zak transform and quantum Weyl-Heisenberg transform.
متن کاملGeneral Time-Frequency Distribution Series
In this paper, we present a new and robust method, general time-frequency distribution series (TFDS), for time-frequency analysis. We also introduce the concept of local interference and global interference and show that the local interference is important and the global interference is less important in TF analysis. The TFDS is very general. With only one parameter, order of the TFDS, one can ...
متن کاملFrequency conversion by exploiting time in transformation optics
The fundamental framework of transformation optics describes how coordinate transformations on electromagnetic fields can be physically realized through complex material parameters. This approach includes the possibility of transforming time as well as space, but the applications of such transformations remain relatively unexplored. Here we analyze the material properties and wave effects of a ...
متن کاملFrequency Switching of Quantum Harmonic Oscillator with time-dependent frequency
An explicit solution of the equation for the classical harmonic oscillator with smooth switching of the frequency has been found . A detailed analysis of a quantum harmonic oscillator with such frequency has been done on the base of the method of linear invariants. It has been shown that such oscillator possesses cofluctuant states, different from widely studied Glauber’s coherent and ”ideal” s...
