Entanglement of Quantum Memories by Interfering Distinguishable Photons

Abstract

Time-resolved photon detection can be used to generate entanglement between non-identical qubits that emit distinguishable photons, which may be necessary for future modular quantum systems. We experimentally realize this process using remotely trapped ytterbium ions.

Entanglement of distinguishable quantum memories

Time-resolved photon detection can be used to generate entanglement between distinguishable photons. This technique can be extended to entangle quantum memories that emit photons with different frequencies and identical temporal profiles without the loss of entanglement rate or fidelity. We experimentally realize this process using remotely trapped ${}^{171}{\mathrm{Yb}}^{+}$ ions where heralded entanglement is generated by interfering distinguishable photons. This technique may be necessary for future modular quantum systems and networks that are composed of heterogeneous qubits.

Analysis of photon-mediated entanglement between distinguishable matter qubits

A. M. Dyckovsky, Steven Olmschenk

We theoretically evaluate establishing remote entanglement between distinguishable matter qubits through interference and detection of two emitted photons. The fidelity of the entanglement operation is analyzed as a function of the temporal- and frequency-mode matching between the photons emitted from each quantum memory. With a general analysis, we define limits on the absolute magnitudes of temporal- and frequency-mode mismatches in order to maintain entanglement fidelities greater than 99$%$ with two-photon detection efficiencies greater than 90$%$. We apply our analysis to several selected systems of quantum memories. Results indicate that high fidelities may be achieved in each system using current experimental techniques, while maintaining acceptable rates of entanglement. Thus, it might be possible to use two-photon-mediated entanglement operations between distinguishable quantum memories to establish a network for quantum communication and distributed quantum computation.
