“…Additionally, from both figures 7(a) and (b), this fact can be understood that, whenever n b th < 0.1 holds, magnon and photon statistics do not critically change. So, considering the low temperature (of the order ≃ 0.4 mK which is accessible with the present experimental capabilities [81,82]) and the above-explained facts, the validity of our results can be confirmed.…”

Magnon and photon blockade implementation and manipulation have significant practical applications in quantum information processing and quantum metrology due to their tight relations to single-photon and -magnon source devices. In this paper, we propose an experimentally feasible hybrid scheme for the dynamical description of the tripartite interacting system consisting of magnon and phonon modes with photons in an optomechanical system, from which we aim to explore the quantum statistics, as well as the magnon and photon blockade phenomenon. To achieve the purpose, the dissipative solution of the system is obtained with the help of the Lindblad master equation. Via employing the equal-time second-order correlation function and using the steady state solution of the system, the statistics and blockade effects of magnon and photon are analyzed and also their dependence on the parameters involved in the system are discussed. Utilizing feasible parameters, our simulations illustrate that, sub-Poissonian behavior and therefore, blockade of magnon and photon are simultaneously achieved. More importantly, the mentioned blockade effects can be obtained in a range of parameters (and not with specific) which makes our proposal easy to access, experimentally. Considering the above realizations, the introduced scheme opens up a pathway to design single-magnon and - photon generators, which are of crucial importance in advanced quantum science and technologies.

“…In particular, in the short-range case with α → ∞, the relation becomes exact through the Jordan-Wigner mapping [80]. In this section, we review the main properties of the model with general power law couplings as in equation (1). For reasons that will become clear later, we restrict ourselves to the regime α 1 , α 2 > 1.…”

“…Such devices permeate our daily life and are as well crucial for technology advances. Few out of countless examples span from fuel-based vehicles, household air conditioners and refrigerators to the dilution refrigerators for quantum applications [1]. Fault-tolerant quantum computing [2] represents the latest technological challenge, which in recent years has attracted significant research efforts [3][4][5][6][7][8][9].…”

The employment of long-range interactions in quantum devices provides a promising route towards enhancing their performance in quantum technology applications. Here, the presence of long-range interactions is shown to enhance the performances of a quantum heat engine featuring a many-body working substance. We focus on the paradigmatic example of a Kitaev chain undergoing a quantum Otto cycle and show that a substantial thermodynamic advantage may be achieved as the range of the interactions among its constituents increases. Interestingly, such an advantage is most significant for the realistic situation of a finite time cycle: the presence of long-range interactions reduces the non-adiabatic energy losses, by suppressing the detrimental effects of dynamically generated excitations. This effect allows mitigating the trade-off between power and efficiency, paving the way for a wide range of experimental and technological applications.

“…XPERIMENTS in Quantum Information Science and Technology mostly operate at extremely low temperatures [1][2][3]. In solid state devices this is usually a millikelvin range achieved in the He 3 -He 4 dilution refrigerator [4]. Of high interest is the understanding of quantum material properties on the nanoscale [5][6][7].…”

“…The helium shortage and high pricing accelerated the development and adaptation of the so-called 'dry' cryogenic systems, which are widely used for applications such as superconducting qubits [4]. However, using such systems for advanced applications such as microscopy remains limited, in part, due to internal vibrations and noises in the experiments caused by those vibrations.…”

Closed cycle He 3 -He 4 dilution cryostats became the platform of choice in quantum sciences in the era of helium shortage. However, in many experiments, the mechanical vibrations induced by the pulsed cryocoolers present a significant drawback reflected both in electronic and mechanical noises. Here, we present a hybrid dilution cryostat platform; we have automated a commercial closed-cycle system to operate on a cryocooler or on a liquid helium 'battery'. We implemented a scanning SQUID microscope in the hybrid dilution refrigerator. In this work we show the design of the hybrid setup and how its operation eliminates vibration artefacts in magnetic imaging.
