Coherent Spin-Photon Interface with Waveguide Induced Cycling Transitions
نویسندگان
چکیده
Solid-state quantum dots are promising candidates for efficient light-matter interfaces connecting internal spin degrees of freedom to the states emitted photons. However, selection rules prevent combination control and optical cyclicity in this platform. By utilizing a photonic crystal waveguide we here experimentally demonstrate up $\approx15$ through state engineering while achieving high fidelity initialization coherent control. These capabilities pave way towards scalable multi-photon entanglement generation on-chip spin-photon gates.

Spin-photon interface and spin-controlled photon switching in a nanobeam waveguide.
The spin of an electron is a promising memory state and qubit. Connecting spin states that are spatially far apart will enable quantum nodes and quantum networks based on the electron spin. Towards this goal, an integrated spin-photon interface would be a major leap forward as it combines the memory capability of a single spin with the efficient transfer of information by photons. Here, we demo...
متن کاملAsymmetric coherent photon tunneling filter in an optical waveguide structure
Based on the well-known electron coherent tunneling phenomenon, by simulation, a photonic tunneling filter fabricated in an optical waveguide is proposed. The Bragg grating structure is applied as the photonic barrier. Two photonic barriers confine a coherent resonance cavity or photon-quantum-well. We report an asymmetric-barrier structure with opposite phase. In this configuration, the centra...
متن کاملSolid-state spin-photon quantum interface without spin-orbit coupling.
We show that coherent optical manipulation of a single confined spin is possible even in the absence of spin-orbit coupling. To this end, we consider the non-Markovian dynamics of a single valence orbital hole spin that has optically induced spin-exchange coupling to a low-temperature partially polarized electron gas. We show that the fermionic nature of the reservoir induces a coherent compone...
متن کاملAn Entanglement Study of Superposition of Qutrit Spin-Coherent States
Considering generalized concurrence as the criterion of entanglement, we study entanglement properties of superposition of two qutrit coherent states, as a function of their amplitudes. These states may attain maximum entanglement or no entanglement at all, depending on the choice of the parameters involved. The states revealing maximum entanglement also display the maximum violations of the Be...
متن کاملPhoton blockade induced Mott transitions and XY spin models in coupled cavity arrays
The non-interacting nature of light makes the observation of photonic quantum phase transitions an impossible task. We demonstrate how a photonic insulator type of phase(Mott phase) can arise in an array of coupled high Q electromagnetic cavities and show how to drive the system to a superfluid state. Each cavity site is coupled resonantly to a single two level system (atom/quantum dot/Cooper p...
