Entanglement swapping with two co-trapped 40Ca+ ions for quantum repeater application

Abstract

We demonstrate Hong-Ou-Mandel interference of 854-nm photons emitted by and entangled with two co-trapped 40Ca+ ions, excited by nanosecond 393-nm laser pulses. We present evidence for atom-atom entanglement following a photonic Bell state measurement.

Quantum repeater segment with free-space coupled co-trapped ions using telecom photon interference

Max Bergerhoff, Pascal Baumgart, Christian Haen +5 more

A quantum repeater segment is a basic building block of a quantum repeater, generating buffered entanglement of quantum memories to connect quantum repeater cells. It also enables the connection between quantum computers. In the implementation we present here, photons emitted from two co-trapped free-space coupled $^{40}$Ca$^+$ ions are converted to the telecom-C band and interfered after transmission over 440$\,$m of optical fiber (220$\,$m per arm), where a photonic Bell measurement is performed to create entanglement between the memories. With this scheme we generate an entangled $\left|Ψ^+\right\rangle$ Bell state with $\ge 68(8)\,$% fidelity, highlighting trapped $^{40}$Ca$^+$ ions as a promising quantum repeater hardware platform.

Frequency-multiplexed Hong-Ou-Mandel interference

Mayuka Ichihara, Daisuke Yoshida, Feng-Lei Hong +1 more

The implementation of quantum repeaters needed for long-distance quantum communication requires the generation of quantum entanglement distributed among the elementary links. These entanglements must be swapped among the quantum repeaters through Bell-state measurements. This study aims to improve the entanglement generation rate by frequency multiplexing the Bell-state measurements. As a preliminary step of the frequency-multiplexed Bell-state measurements, three frequency modes are mapped to a temporal mode by an atomic frequency comb prepared in ${\mathrm{Pr}}^{3+}$ ion-doped ${\mathrm{Y}}_{2}{\mathrm{SiO}}_{5}$ crystals using a weak coherent state, and Hong-Ou-Mandel interference, which is a measure of the indistinguishability of two inputs, is observed in each frequency mode by coincidence detection. The visibility for all the modes was 40%--42% (theoretically up to 50%). Furthermore, we show that a mixture of different modes is avoided. The present results are connected to frequency-selective Bell-state measurements and therefore frequency-multiplexed quantum repeaters.

Indistinguishability of photonic qubits emitted from trapped $^{40}$Ca$^+$ ions via pulsed excitation

Pascal Baumgart, Max Bergerhoff, Jonas Meiers +2 more

We investigate the indistinguishability of Raman photons generated from two trapped $^{40}$Ca$^+$ ions using few-nanosecond excitation pulses. We elucidate how spontaneous scattering back to the initial state affects Hong-Ou-Mandel interference. We identify the mean number of back-decays as a measurable single-emitter quantity that correlates with achievable interference visibility of photons from two identical emitters.

Indistinguishability of single Raman photons from single atoms

Pascal Baumgart, Max Bergerhoff, Jürgen Eschner

We theoretically investigate the indistinguishability of single photons generated from single trapped $^{40}$Ca$^+$ ions in a Raman scattering process driven by few-nanosecond excitation pulses. Of particular interest is how spontaneous decay back to the initial state affects Hong-Ou-Mandel (HOM) photon interference. Numerical simulations identify the mean number of back-decays as a measurable quantity that correlates with achievable HOM visibility. Optimization of the excitation pulse with respect to a trade-off between photon yield and indistinguishability is analyzed. Finally, we compare the performance of different trapped-ion species for long-range dual-rail entanglement swapping via HOM photon interference.

Single Atom – Single Photon Interfaces

Felix Rohde, Carsten Schuck, Markus Hennrich +7 more

In an experimental system of two distant ion traps we trap simultaneously strings of Ca+ ions and observe Hong-Ou-Mandel interference between their scattered photons. We also generate entangled photon pairs whose frequency and bandwidth are matched to an absorption line in the ions, and work towards heralded single photon – single ion interaction.

It also enables the connection between quantum computers. In the implementation we present here, photons emitted from two co-trapped free-space coupled 40^{40}40Ca+^++ ions are converted to the telecom-C band and interfered after transmission over 440 \,m of optical fiber (220 \,m per arm), where a photonic Bell measurement is performed to create entanglement between the memories. With this scheme we generate an entangled ∣Ψ+⟩\left|Ψ^+\right\rangle∣Ψ+⟩ Bell state with ≥68(8) \ge 68(8)\,≥68(8)% fidelity, highlighting trapped 40^{40}40Ca+^++ ions as a promising quantum repeater hardware platform.
