“…A number of designs are presented, Müller et al propose a fan-out gate C-NOT n based on Rydberg blockade and electromagnetically induced transparency (EIT), with which a single control atom switches the states of n target atoms [125]; Isenhower, Saffman, and Mølmer suggest a multi-qubit Toffoli gate C n -NOT [126], where spin-flip of the target qubit is conditioned on n control qubits; Su et al introduce a multi-qubit controlled phase gate via modified Rydberg antiblockade [127]; Shi outlines a scheme for three-qubit Deutsch gate [128]. These multi-qubit gates represent highly parrallel quantum operations, which support one-step generation of highly entangled states [129], simulations of many-body interactions [130], as well as efficient implementations of quantum algorithms [131].…”

Quantum information processing based on Rydberg atoms emerged as a promising direction two decades ago. Recent experimental and theoretical progresses have shined exciting light on this avenue. In this concise review, we will briefly introduce the basics of Rydberg atoms and their recent applications in associated areas of neutral atom quantum computation and simulation. We shall also include related discussions on quantum optics with Rydberg atomic ensembles, which are increasingly used to explore quantum computation and quantum simulation with photons.

“…quantum entanglement [9][10][11], generation of single photons [12,13], collective emission of photons [14], etc. The manipulation of a strongly-interacting atomic ensemble can enable the implementation of single ensemble qubit gate [15], a many-particle GHZ state [16][17][18], a photon reflection phase [19], and the creation of control-ensemble entanglement [20]. So far, many of these achievements depend on the Rydberg blockade mechanism since it causes a single atom's excitation shared by N ensemble atoms within the range of blockade radius [21][22][23][24].…”

Strongly-interacting Rydberg atomic ensembles have shown intense collective excitation effects due to the inclusion of single Rydberg excitation shared by multiple atoms in the ensemble. In this paper we investigate a counter-intuitive Rydberg excitation facilitation with a strongly-interacting atomic ensemble in the strong probe-field regime, which is enabled by the role of a control atom nearby. Differing from the case of a single ensemble, we show that, the control atom’s excitation adds to a second two-photon transition onto the doubly-excited Rydberg state, arising an excitation facilitation for the ensemble atoms. Our numerical studies depending on the method of quantum Monte Carlo wavefunction, exhibit the observation constraints of this excitation facilitation effect under practical experimental conditions. The results obtained can provide a flexible control for the excitation of Rydberg atomic ensembles and participate further uses in developing mesoscopic Rydberg gates for multiqubit quantum computation.

“…In the field of preparation of entangled states, the "fractional stimulated Raman adiabatic passage (f-STIRAP)" method has been widely used. [28][29][30] It is an extension of "stimulated Raman adiabatic passage (STIRAP)" method to realize partial transfer of population distribution under the adiabatic condition. This method is applicable to not only the state generation scheme, but also the field of preparing quantum gate, [31,32] achieving polar molecular condensates [33] and wavelength conversion.…”

Generation of N‐particle W State with Trapped Λ‐Type Ions by Transitionless Quantum Driving

et al. 2021

An efficient scheme to generate multiparticle W state based on transitionless quantum driving (TQD) with trapped ions is proposed. In the TQD scheme, the effective Hamiltonian can be obtained with the help of quantum Zeno dynamics and large off‐resonance condition, and the multiparticle W state can be generated with high fidelity. The influence of decoherence induced by the ionic spontaneous emission and the ambient heating, and the sensitivity of the TQD scheme to some experimental errors are discussed by numerical simulation. The result demonstrates that the TQD scheme is faster than that only via the fractional stimulated Raman adiabatic passage and robust against decoherence and operation imperfection.
