Visualizing quantum mechanics in an interactive simulation – Virtual Lab by Quantum Flytrap

Abstract

Virtual Lab by Quantum Flytrap is a no-code online laboratory of an optical table, presenting quantum phenomena interactively and intuitively. It supports a real-time simulation of up to three entangled photons. Users can place typical optical elements (such as beam splitters, polarizers, Faraday rotators, and detectors) with a drag-and-drop graphical interface. Virtual Lab operates in two modes. The sandbox mode allows users to compose arbitrary setups. Quantum Game serves as an introduction to Virtual Lab features, approachable for users with no prior exposure to quantum mechanics. We introduce visual representation of entangled states and entanglement measures. It includes interactive visualizations of the ket notation and a heatmap-like visualization of quantum operators. These quantum visualizations can be applied to any discrete quantum system, including quantum circuits with qubits and spin chains. These tools are available as open-source TypeScript packages -Quantum Tensors and BraKetVue. Virtual Lab makes it possible to explore the nature of quantum physics (state evolution, entanglement, and measurement), to simulate quantum computing (e.g., the Deutsch-Jozsa algorithm), to use quantum cryptography (e.g., the Ekert protocol), to explore counterintuitive quantum phenomena (e.g., quantum teleportation and the Bell inequality violation), and to recreate historical experiments (e.g., the Michelson-Morley interferometer).

Quantum computing with oscillatory quanta

“…Prior to about 2000, it was believed that quantum algorithms require systems that are truly quantum in nature. However, further research on fundamental aspects of quantum algorithms has shown [21][22][23][24][25][26] that sub-atomic-level quantum systems are not mandatory for most quantum algorithms, and that many quantum algorithms can be realized with classical systems involving harmonic oscillations. Classical systems can be suitable for visualizing some concepts of quantum algorithms and quantum computing, but they are not likely to be widespread, since they are extremely slow in operations, consume a lot of power, and are difficult to mass produce.…”

“…Quantum entanglement based on synchronous oscillations implies more and better possibilities of quantum computing. It can lead to new types of quantum computers, [21][22][23][24][25][26] which can be more powerful and reliable than emulated quantum computers proposed earlier.…”

Quantum games and interactive tools for quantum technologies outreach and education

“…Virtual Lab by Quantum Flytrap (2019) 140 is a real-time online simulation of an optical table, supporting up to three entangled photons. The Lab uses a drag-and-drop interface for positioning optical elements, such as photon sources, mirrors, polarizing and nonpolarizing beam splitters, and Faraday rotators.…”

“…One of which, is measuring entanglement between a pair of particles by QDF and QFT models, aka correlated particles [7] , [8] , [9] , 45] . Albert Einstein called this correlation, “a spooky action at a distance,” a property known as entanglement [46] . If one state is known, the entangled state can be predicted with a , given no information loss occurs.…”
