Quantum memristors
Technology based on memristors, resistors with memory whose resistance depends on the history of the crossing charges, has lately enhanced the classical paradigm of computation with neuromorphic architectures. However, in contrast to the known quantized models of passive circuit elements, such as inductors, capacitors or resistors, the design and realization of a quantum memristor is still miss...
متن کاملQuantum Memristors in Quantum Photonics
We propose a method to build quantum memristors in quantum photonic platforms. We firstly design an effective beam splitter, which is tunable in real-time, by means of a Mach-Zehnder-type array with two equal 50:50 beam splitters and a tunable retarder, which allows us to control its reflectivity. Then, we show that this tunable beam splitter, when equipped with weak measurements and classical ...
متن کاملMemristors by Quantum Mechanics
Memristor behavior is explained with a physical model based on quantum mechanics that claims charge is naturally created anytime energy is absorbed at the nanoscale. Quantum mechanics requires specific heat to vanish at the nanoscale, and therefore the electrical resistive heating in the memristor cannot be conserved by an increase in temperature. Conservation proceeds by frequency up-conversio...
متن کاملQuantum Memristors with Superconducting Circuits
Memristors are resistive elements retaining information of their past dynamics. They have garnered substantial interest due to their potential for representing a paradigm change in electronics, information processing and unconventional computing. Given the advent of quantum technologies, a design for a quantum memristor with superconducting circuits may be envisaged. Along these lines, we intro...
متن کاملQuantum Phase Transitions Go
U nderstanding matter—a collection of many interacting constituents, such as atoms and electrons—is a major endeavor in physics. While most studies in this field have focused on matter that is in thermal equilibrium with its environment, many phenomena occurring in nature involve matter out of equilibrium. The reason for this disparity may lie in the often-repeated observation that, to paraphra...
