  • Quantum communications

    Summary form only given. Quantum mechanics allows a number of communications protocols that would not be possible classically, including provably-secure messages (quantum cryptography), increased channel capacity, and the ability to transmit an unknown quantum state (quantum teleportation). Practical systems for quantum cryptography have now been demonstrated by a number of groups. I will begin by reviewing the most commonly-used methods for quantum cryptography, including the advantages and disadvantages of each in practical applications. The maximum range of current quantum cryptography systems is limited by the fact that optical amplifiers would destroy the quantum coherence of single photons and cannot be used in these kinds of systems. One potential solution to this problem is the transmission of single photons in free space, which would allow a global system for quantum cryptography based on a network of satellites and ground stations. Free-space quantum cryptography systems of that kind have now been demonstrated over relatively short distances. The range of quantum cryptography systems in optical fibers can also be extended using quantum repeaters that make use of entanglement swapping, entanglement purification, and quantum teleportation. These same techniques could also be used to implement a "quantum Internet" for the transmission of qubits from one quantum computer to another. The practical challenges that will have to be met in order to implement quantum repeaters and quantum teleportation over large distances will be discussed.

  • Efficient scheme for optimizing quantum fourier circuits

    In quantum circuits, importing of additional qubits can reduce the operation time and prevent decoherence induced by the environment. However, excessive qubits may make the quantum system vulnerable. This paper describes how to relax existing qubits without additional qubits to significantly reduce the operation time of the quantum Fourier circuit compared to a circuit without optimization. The results indicate that this scheme makes full use of the qubits relaxation. The concepts can be applied to improve similar quantum circuits and guide the physical implementations of quantum algorithms or devices.

  • Excess noise in bandwidth-resource-efficient entanglement distribution

    In this work, we emphasize the importance of properly designing a bandwidth- resource-efficient entanglement distribution system. In particular, we point out that inappropriate setting of wavelength demultiplexing channel bandwidth with respect to pump spectral width could affect entanglement quality. It is widely known that the photon coherence length can be made longer than pump pulsewidth by narrowband filtering so as to improve photon temporal coherence, however, the excess noise that accompanies narrowband filtering has not been studied. The use of narrowband sources of entangled photon-pairs avoids this problem but one needs to wavelength-multiplex many such narrowband sources in order to implement bandwidth-resource-efficient entanglement distribution. We show how to reduce excess noise while maintaining a high photon temporal coherence for a bandwidth-resource-efficient system that uses broadband sources.

  • Entangled photons from a ps-source - bandwidth considerations

    This study investigates the prospects in the entanglement of the photons in their spectral properties. Furthermore new quantum communication protocols involve the simultaneous entanglement of photons in more than just one parameter. In spontaneous parametric downconversion, it is possible to simultaneously entangle photons in their polarization and energy or wavelength. Schemes to realize this double variable entanglement are also discussed.

  • Mathematical and Physical Model of the Generation and the Transmission of Single Photon and Its Quantum State Representations

    From Maxwell equation group, considering the mass of photon m, a two- dimensional finite difference time domain (FDTD) recursive formula is derived, the mathematical physical model of photon transmission is established, and the process of photon generation is simulated successfully. Based on the hypothesis of TEZ wave transmission, the process of photon transmission along the Z axis is given without considering the mass of the photon, producing the spin entangle between two photons. In the case of considering photon mass, a velocity component is generated which perpendicular to the propagation direction, resulting in the angular momentum of the orbit, thus causing a new entanglement. Moreover, the image of the photon entanglement and the quantum state representation of two entangled photons are obtained. Also, the quantum state generated by the angular momentum of the photon orbit cannot be equivalent to linear polarization when the velocity component perpendicular to the direction of propagation exceeds 0.3 times of the speed of light in the vacuum, a quantum state representation of the single photon twist needs to be further found.
