“…Furthermore, the endeavors to address the response of a system under the influence of an external driving focusing on understanding the out-of-equilibrium dynamics have opened new perspectives. In such direction, we found the control of Mott-insulator and superfluid states 31 and the appearance of dynamical hysteresis in photonic devices 29,32 .…”

“…Dissipative effects arise from imperfect mirrors with photonic decay (γ c i ) and spontaneous emission with atomic decay (γ a i ) per site (i = 1, 2). The modulation serves different purposes such as manipulation of qubits 31,33 , sideband transitions 34 and control of atomic quantum gases 35 . The dynamics of the light-matter interaction is given by the Jaynes-Cummings-Hubbard (JCH) Hamiltonian,…”

Information processing and storing by the same physical system is emerging as a promising alternative to traditional computing platforms. In turn, this requires the realization of elementary units whose memory content can be easily tuned and controlled. Here, we introduce a polariton-based quantum memristor where the memristive nature arises from the inter-cavity polariton exchange and is controlled by a time-varying atom-cavity detuning. A dynamical hysteresis is characterized by the fluctuations in the instantaneous polariton number, where the history information is encoded into a dynamical phase. Using a Lindblad master equation approach, we find that features of the quantum memristor dynamics, such as the area and circulation of the hysteresis loop, showcase a kind of "plasticity" controlled by quantum state initialization. This makes this quantum memristor very versatile for a wide range of applications.

“…In general, equilibrium QPT are well understood and provide a suitable path for unravelling the properties of a system 2-4 . In contrast, nonequilibrium QPT belong to an ongoing field that poses new challenges and opens new avenues to study QPT [5][6][7][8] .…”

“…These QC techniques serves multiple purposes including state preservation, state-to-state transfer [9], dynamical decoupling in open systems [10][11][12] and trajectory tracking [13,14]. Furthermore, we have witnessed powerful applications across multiple platforms including atomic systems [16,17], lightmatter systems [18,19], solid-state devices [20,21], trapped ions [22], among other. Dynamical QC stems from a timedependent Hamiltonian that steers the dynamics [26], and it is subjected to several constraints like laser power, inhomogeneous frequency broadening, and relaxation processes, to name a few.…”
