“…In this regard, we show that, by optimizing the parameters of a many-particle system, a small number of resonators can be used in this configuration to implement the highly efficient storage of quantum information, which greatly simplifies the technological implementation. It is worth noting that involvement of long-lived atoms in a system of high-Q resonators will require the search for additional methods for controlling atomic coherence and the use of quantum transitions of three- and multi-level quantum systems with different character of inhomogeneous broadening [ 18 , 51 , 52 , 53 , 54 ] will be important in the implementation of the multiresonator echo based QM protocols.…”

“…For example, this is the case for QM based on slow light [ 15 , 16 ]. The cavity-assisted photon echo QM, often called impedance-matched QM [ 11 , 12 ], has been demonstrated in a number of experiments on AFC and ROSE protocols [ 17 , 18 , 19 , 20 , 21 ], which show the possibility of implementing high efficiency, currently achieving up to

. Moreover, the impedance-matched approach significantly facilitates the requirements to the optical density of resonant transition and, consequently, expands the practical possibilities in the implementation of existing QM protocols, which has become especially important for the AFC protocol [ 19 , 20 , 22 ].…”

We develop an integrated efficient multiresonator quantum memory scheme based on a system of three interacting resonators coupled through a common resonator to an external waveguide via switchable coupler. It is shown that high-precision parameter matching based on step-by-step optimization makes it possible to efficiently store the signal field and enables on-demand retrieval of the signal at specified time moments. Possible experimental implementations and practical applications of the proposed quantum memory scheme are discussed.

“…Moreover, it can be used for applications in quantum memories where light-matter interaction is used to store and retrieve optical fields in the form of photon echoes (PE) [3][4][5] . In solid-state systems based on color centers and rare earth ions, significant progress has been achieved in that respect [6][7][8][9][10][11] . Yet, the search for new systems where similar or alternative approaches can be pursued on much faster time scales is of great interest [12][13][14][15][16] .…”

Extending the time of coherent optical response in ensemble of singly-charged InGaAs quantum dots

et al. 2022

The ability to extend the time scale of the coherent optical response from large ensembles of quantum emitters is highly appealing for applications in quantum information devices. In semiconductor nanostructures, spin degrees of freedom can be used as auxiliary, powerful tools to modify the coherent optical dynamics. Here, we apply this approach to negatively charged (In,Ga)As/GaAs self-assembled quantum dots which are considered as excellent quantum emitters with robust optical coherence and high bandwidth. We study three-pulse spin-dependent photon echoes subject to moderate transverse magnetic fields up to 1 T. We demonstrate that the timescale of coherent optical response can be extended by at least an order of magnitude by the field. Without magnetic field, the photon echo decays with T2 = 0.45 ns which is determined by the radiative lifetime of trions T1 = 0.26 ns. In the presence of the transverse magnetic field, the decay of the photon echo signal is given by spin dephasing time of the ensemble of resident electrons T2,e ∼ 4 ns. We demonstrate that the non-zero transverse g-factor of the heavy holes in the trion state plays a crucial role in the temporal evolution and magnetic field dependence of the long-lived photon echo signal.
