“…However, these quantum memories have an inhomogeneous bandwidth of approximately MHz, and the pulse width of photons that can be stored is suppressed to the microsecond order. [1][2][3][4][5][6][7][8] To realize an ultrafast pulse storage, we have demonstrated a photon-echo-based quantum memory using a self-assembled InAs quantum dot ensemble. This quantum memory has a bandwidth of 7.2 THz due to the large inhomogeneous broadening of quantum dots and enables femtosecond pulse storage.…”

We developed a THz bandwidth quantum memory using a photon echo technique in InAs quantum dot ensemble with a large inhomogeneous broadning. To improve photon echo generation efficiency, we applied Adiabatic Rapid Passage (ARP) technique to quantum manipulation of quantum memory. In addition, we developed pulse pumped up conversion single photon detector (UCSPD) which enables us to achieve the femtosecond scale temporal resolution and we successfully demonstrated femtosecond time bin photon echo signals.

“…Photon pairs (biphotons) are constitute a two-photon state of light with a high degree of nonclassical correlations between, e.g., their detection times and energies of photons in a pair [1]. Due to these properties, sources of photon pairs provide a reliable foundation for the development of new fields of quantum technologies including quantum visualization [2,3], quantum optical coherence tomography [4], quantum spectroscopy and nonlinear microscopy [5,6], and optical quantum memory and quantum communications [7,8].…”

The generation of interband photon pairs with wavelengths near 0.5 and 1.6 μm in a photonic-crystal fiber under low-power cw optical pumping by a diode laser with a central wavelength of 0.8 μm has been experimentally demonstrated. It has been found that the generation rate of entangled photons under cw pumping is comparable with values obtained with pulsed pumping by a femtosecond Ti:sapphire laser if the average cw pump power is an order of magnitude higher than the average pulsed pump power. The reached rates of photon generation are ensured by the used photonic-crystal fiber with a small effective mode area and a special dispersion profile. The reached low noise in the output signal is ensured by the separation of carrier frequencies of generated photons into different spectral bands.

“…They are at the center of a number of quantum storage protocols, in the form of gases [2,3] or solid state [4,5]. Among the most interesting solid state candidates, rare-earth ion-doped crystals (REIC) are particularly attractive due to their long optical coherence lifetimes at cryogenic temperatures [6] and are at the center of a number of actively developed quantum memory protocols [7,8,9]. In these light-matter interfaces, the optical depth of the medium is an important figure of merit since it enables high storage and retrieval efficiency [10,11,5].…”

It was recently shown that the optical excitation of rare-earth ions produces a local change of the host matrix shape, attributed to a change of the rare-earth ion's electronic orbital geometry. In this work we investigate the consequences of this piezoorbital backaction and show from a macroscopic model how it yields a disregarded ion-ion interaction mediated by mechanical strain. This interaction scales as 1/r 3 , similarly to the other archetypal ion-ion interactions, namely electric and magnetic dipole-dipole interactions. We quantitatively assess and compare the magnitude of these three interactions from the angle of the instantaneous spectral diffusion mechanism, and reexamine the scientific literature in a range of rare-earth doped systems in the light of this generally underestimated contribution.
