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).

Virtual Lab by Quantum Flytrap explores novel ways to represent quantum phenomena in an interactive and intuitive way. It is an online laboratory with a real-time simulation of an optical table, supporting up to 3 entangled particles. We have created a highly visual no-code interface and an introductory Quantum Game to make the Virtual Lab approachable for users without prior exposure to quantum mechanics. At the same time, a configurable sandbox mode with customizable elements makes it useful for students, lecturers, and scientists. Virtual Lab provides a way to explore exact quantum states, entanglement, and the probabilistic nature of quantum physics. We provide ways to simulate quantum computing (e.g. Deutsch-Jozsa algorithm), use quantum cryptography (e.g. BB84 protocol), explore counterintuitive quantum phenomena (e.g. quantum teleportation), and recreate historical experiments (e.g. Michaelson-Morley interferometer).

We present a web-based software tool, the Virtual Quantum Optics Laboratory (VQOL), that may be used for designing and executing realistic simulations of quantum optics experiments. A graphical user interface allows one to rapidly build and configure a variety of different optical experiments, while the runtime environment provides unique capabilities for visualization and analysis. All standard linear optical components are available as well as sources of thermal, coherent, and entangled Gaussian states. A unique aspect of VQOL is the introduction of non-Gaussian measurements using detectors modeled as deterministic devices that "click" when the amplitude of the light falls above a given threshold. We describe the underlying theoretical models and provide some illustrative examples. We find that VQOL provides a faithful representation of many experimental quantum optics phenomena and may serve as both a useful instructional tool for students as well as a valuable research tool for practitioners.
Abstract Quantum computing utilizes the concepts of quantum mechanics, including superposition and entanglement, to execute calculations that are impractical for traditional computers. Central to this approach is the qubit, a quantum equivalent of the traditional bit, capable of being in a superposition of states. Nonetheless, the conceptual essence of quantum states renders them hard to visualize and comprehend, particularly for students and professionals who are unfamiliar with the domain. To tackle this issue, we created an interactive qubit visualization tool using Streamlit, enabling real-time exploration of qubit behavior under quantum operations.The app enables users to control qubit states directly by modifying the real and imaginary components of probability amplitudes, guaranteeing the normalization of the state vector. It also incorporates a set of essential quantum gates, including Hadamard, Pauli-X, Pauli-Y, and Pauli-Z, as well as continuous rotation gates (Rx, Ry, Rz). In contrast to distinct button-driven functions, the rotation gates are implemented dynamically via angle sliders, enabling users to witness seamless, real-time updates to the qubit state. This provides an intuitive understanding of qubit evolution as it revolves around the Bloch sphere axes.The tool displays the outcomes in both numerical and graphical formats. Users are able to observe the quantum state vector, as well as the probabilities of obtaining |0⟩ and |1⟩, and visual depictions through probability bar charts and Bloch sphere visualizations. By providing a live, interactive setting, this platform connects the divide between mathematical theory and conceptual grasp of quantum mechanics. It functions as both a learning tool for students and a prototyping support for researchers, rendering quantum computation more approachable and captivating.
Quantum computing is a new way of doing things that uses quantum mechanics to do things that classical systems can't. These things include superposition, entanglement, and interference. Quantum teleportation is one of the most basic protocols that shows how the full quantum state of a qubit can be sent to a different place without moving the particle. It only uses shared entanglement and a classical communication channel. Even though this protocol is theoretically beautiful, it is still hard for students and new researchers to picture and understand it on their own. This paper describes an interactive quantum circuit simulator that runs on the web and was made with Python Flask, IBM's Qiskit library, and Three.js. It was made to show quantum teleportation in real time. Through a browser interface, users can build quantum circuits, use standard gates like Hadamard, Pauli-X, Pauli-Z, CNOT, and multiqubit gates, and see dynamic Bloch sphere updates that show how the state of the qubit changes after each operation. The backend uses Qiskit's statevector simulator to make sure the math is right, and the frontend, which is powered.by Three.js, shows quantum states in three-dimensional geometric forms. Testing confirms that the simulation fidelity is close to 1 under ideal conditions, which means that the protocol was implemented correctly. The proposed framework makes it easier to get into quantum education by getting rid of complicated local setup requirements and giving immediate visual feedback. This makes it easier to go from quantum theory to hands-on experimentation
