“…We expect that a reduction of the interaction cross section, for example, using a small-diameter ridge waveguide or structures fabricated by focused-ion-beam milling4647, can improve the phase sensitivity by more than a factor of 100 (see equation 1). Furthermore, the ratio between the radiative lifetime γ and the detuning Δ has to be increased beyond its current value of 8.1 kHz/(2 π × 65 MHz)∼2 × 10 −5 —as we discuss below, this ratio can in principle approach one per cent.…”

Non-destructive detection of photonic qubits is an enabling technology for quantum information processing and quantum communication. For practical applications, such as quantum repeaters and networks, it is desirable to implement such detection in a way that allows some form of multiplexing as well as easy integration with other components such as solid-state quantum memories. Here, we propose an approach to non-destructive photonic qubit detection that promises to have all the mentioned features. Mediated by an impurity-doped crystal, a signal photon in an arbitrary time-bin qubit state modulates the phase of an intense probe pulse that is stored during the interaction. Using a thulium-doped waveguide in LiNbO3, we perform a proof-of-principle experiment with macroscopic signal pulses, demonstrating the expected cross-phase modulation as well as the ability to preserve the coherence between temporal modes. Our findings open the path to a new key component of quantum photonics based on rare-earth-ion-doped crystals.

“…Thus, there is significant impetus to develop other methods to increase photon-ion interactions [13][14][15][16][17]. One solution is to fabricate photonic crystal resonators directly in REI crystals [15,[18][19][20][21]. A large increase in photon-ion coupling is achieved through cavity enhancement of the optical transition [22] and strong * faraon@caltech.edu mode confinement [14,[23][24][25][26].…”

On-chip nanophotonic cavities will advance quantum information science and measurement because they enable efficient interaction between photons and long-lived solid-state spins, such as those associated with rare-earth ions in crystals. The enhanced photon-ion interaction creates new opportunities for all-optical control using the ac Stark shift. Toward this end, we characterize the ac Stark interaction between off-resonant optical fields and Nd 3+ -ion dopants in a photonic crystal resonator fabricated from yttrium orthovanadate (YVO 4 ). Using photon echo techniques, at a detuning of 160 MHz we measure a maximum ac Stark shift of 2π × 12.3 MHz per intracavity photon, which is large compared to both the homogeneous linewidth ( h = 84 kHz) and characteristic width of isolated spectral features created through optical pumping ( f ≈ 3 MHz). The photon-ion interaction strength in the device is sufficiently large to control the frequency and phase of the ions for quantum information processing applications. In particular, we discuss and assess the use of the cavity enhanced ac Stark shift to realize all-optical quantum memory and detection protocols. Our results establish the ac Stark shift as a powerful added control in rare-earth ion quantum technologies.
