LINEAR OPTICAL IMPLEMENTATION OF DISCRETE QUANTUM FOURIER TRANSFORM WITH CONVENTIONAL PHOTON DETECTORS

Abstract

We present a linear optical scheme for implementing two-bit discrete quantum Fourier transform based only on simple linear optical elements, a pair of two-photon polarization entangled states, and the conventional photon detectors that only distinguish between the presence and absence of the photons. The scheme can be implemented with a certain success probability, and the implementation of the scheme in experiment would be an important step towards more complex linear optical quantum computation.

Linear optical implementation of the two-qubit controlled phase gate with conventional photon detectors

Xu‐Bo Zou, Sheng Li Zhang, Ke Li +1 more

We propose a linear optical scheme to implement the nondeterministic two-qubit controlled phase gate with the certain success probability. The proposed setup involves simple linear optical elements, a pair of the two-photon polarization entangled states, and the conventional photon detectors that only distinguish the vacuum and nonvacuum Fock number states. A sophisticated single-photon detector distinguishing one or two photon states is unnecessary. This can greatly simplify the experimental realization of a linear optical quantum computer.

Scheme for implementing linear optical quantum iSWAP gate with conventional photon detectors

Hong‐Fu Wang, Xiao‐Qiang Shao, Yongfang Zhao +2 more

A simple scheme is proposed to implement a two-qubit linear optical quantum iSWAP gate that is a universal gate in quantum computation and quantum information processing. By the interference effect of the polarized photons, a quantum iSWAP gate can be achieved with a low success probability (η4/32, with η being the quantum efficiency of photon detectors). The scheme is based only on simple linear optical elements, a pair of two-photon polarization entangled states, and conventional photon detectors that only distinguish the vacuum and nonvacuum Fock number states, which greatly decreases the experimental difficulty of implementing linear optical quantum computation.

Linear optical implementation of an ancilla-free quantum SWAP gate

Hong‐Fu Wang, Xiao‐Qiang Shao, Yongfang Zhao +2 more

We propose a simple linear optical scheme for directly implementing an ancilla-free two-qubit quantum SWAP gate with high success probability. The proposed setup consists of only simple linear optical elements and photon detectors without introducing additionally ancillary single photons or entangled photons sources. The scheme is feasible and within the reach of current experimental technology.

Linear optical implementation of a single-mode quantum filter and generation of multiphoton polarization entangled states

Xu‐Bo Zou, K. Pahlke, Wolfgang M. Mathis

We propose a scheme to implement a single-mode quantum filter, which selectively eliminates the one-photon state in a quantum state $\ensuremath{\alpha}|0〉+\ensuremath{\beta}|1〉+\ensuremath{\gamma}|2〉.$ The vacuum state and the two-photon state are transmitted without any change. This scheme requires single-photon sources, linear optical elements, and photon detectors. Furthermore, we demonstrate how this filter can be used to realize a two-qubit projective measurement and to generate multiphoton polarization entangled states.

Linear optical generation of multipartite entanglement with conventional photon detectors

Hong‐Fu Wang, Shou Zhang

A simple experimental scheme is proposed to generate a three-photon entangled $W$ state and a genuine four-photon entangled state $|{\ensuremath{\chi}}^{00}⟩$ that has many interesting entanglement properties and possible applications in quantum information processing. These multipartite entangled states can be generated with a certain success probability. We show that even when the quantum efficiency of the detector is $\ensuremath{\eta}=0.75$, the success probability can reach $2.8\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}$ for $W$-state production and $3.0\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}9}$ for $|{\ensuremath{\chi}}^{00}⟩$-state production. The scheme is based only on simple linear optical elements and conventional photon detectors, which greatly decrease the experimental difficulty of implementing linear optical quantum computation.

Controlled generation of four-photon polarization-entangled decoherence-free states with conventional photon detectors

Yan Xia, Jie Song, He‐Shan Song +1 more

We propose a protocol for the controlled generation of four-photon polarization-entangled decoherence-free states with a certain success probability. The proposed setup involves simple linear optical elements, two single-photon polarzaition entangled states, a pair of two-photon polarization entangled states, and conventional photon detectors that only distinguish the vacuum and nonvacuum Fock number states. This makes the protocol more realizable in experiments.
