Hybrid atom-photon quantum gate in a superconducting microwave resonator
We propose a hybrid quantum gate between an atom and a microwave photon in a superconducting coplanar waveguide cavity by exploiting the strong resonant microwave coupling between adjacent Rydberg states. Using experimentally achievable parameters gate fidelities >0.99 are possible on submicrosecond time scales for waveguide temperatures below 40 mK. This provides a mechanism for generating ent...
متن کاملQuantum controlled-phase-flip gate between a flying optical photon and a Rydberg atomic ensemble
Quantum controlled-phase-flip (CPF) gate between a flying photon qubit and a stationary atomic qubit could allow the linking of distant computational nodes in a quantum network. Here we present a scheme to realize quantum CPF gate between a flying optical photon and an atomic ensemble based on cavity input-output process and Rydberg blockade. When a flying single-photon pulse is reflected off t...
متن کاملPhase matching as a gate for photon entanglement
Phase matching is shown to provide a tunable gate that helps discriminate entangled states of light generated by four-wave mixing (FWM) in optical fibers against uncorrelated photons originating from Raman scattering. Two types of such gates are discussed. Phase-matching gates of the first type are possible in the normal dispersion regime, where FWM sidebands can be widely tuned by high-order d...
متن کاملProbing single-molecule dynamics photon by photon
We present the theoretical rationales for data analysis protocols that afford an efficient extraction of conformational dynamics on a broad range of time scales from single-molecule fluorescence lifetime trajectories. Based on correlation analyses, a photon-by-photon approach on one hand provides the highest time resolution, whereas a minimal-binning method on the other hand is most suitable fo...
متن کاملQuantum Dots in Photonic Crystals : From Single photon sources to single photon nonlinear optics
A quautmn dot strongly coupled to a photonic crystal resonator is used to investigate cavity quantum electrodynamics phenomena in solid state physics. Nonlinear optical phenomena snch as photon blockade and photon induced tunneling are observed in this system. The nonliJHmrity of this system is sensitive to intra-crwity photon munbers dos<c to unity, aud it has been used to demonstrate conditio...
