“…We show that a moderatefinesse cavity -compatible with broadband operation -can suppress four-wave mixing noise to a low level. We also point out that the cavity-enhanced memory is nearly perfectly temporal-mode-selective [40], making it an appealing system for chronocyclic encodings of quantum information [41].…”

Quantum memories, capable of storing single photons or other quantum states of light, to be retrieved on-demand, offer a route to large-scale quantum information processing with light. A promising class of memories is based on far-off-resonant Raman absorption in ensembles of Λ-type atoms. However at room temperature these systems exhibit unwanted four-wave mixing, which is prohibitive for applications at the single-photon level. Here we show how this noise can be suppressed by placing the storage medium inside a moderate-finesse optical cavity, thereby removing the main roadblock hindering this approach to quantum memory.

“…(19) and (20), consider an input in the r-channel given by a scalar multiplied by a specific Schmidt mode A in r (t ) = a n ψ (1) n (t ) and the s-channel initially empty A in s (t ) = 0. The outputs after the two stages are then given using Eqs.…”

“…Recent studies have proposed using temporally and spectrally overlapping field-orthogonal optical wave packets, called temporal modes (TMs), to encode information [1]. In classical optical networks, the TMs allow for a new method of multiplexing, and can therefore aid in meeting the increasing demands for the flexible use of bandwidth.…”

. Temporal mode sorting using dual-stage quantum frequency conversion by asymmetric Bragg scattering. Optics Express, 23(18) Abstract:The temporal shape of single photons provides a highdimensional basis of temporal modes, and can therefore support quantum computing schemes that go beyond the qubit. However, the lack of linear optical components to act as quantum gates has made it challenging to efficiently address specific temporal-mode components from an arbitrary superposition. Recent progress towards realizing such a "quantum pulse gate," has been proposed using nonlinear optical signal processing to add coherently the effect of multiple stages of quantum frequency conversion. This scheme, called temporal-mode interferometry [D. V. Reddy, Phys. Rev. A 91, 012323 (2015)], has been shown in the case of three-wave mixing to promise near-unity mode-sorting efficiency. Here we demonstrate that it is also possible to achieve high mode-sorting efficiency using four-wave mixing, if one pump pulse is long and the other short -a configuration we call asymmetrically-pumped Bragg scattering.

“…Temporal modes (TM) of light are a promising resource for quantum information as they span a discrete infinite dimensional encoding basis [1]. Additionally, TM are compatible with standard fibered communication as they share the same polarization, carrier frequency and transverse spatial mode properties.…”
