Publisher

Abstract

Quantum Computing is solving problems across various domain like Quantum state representation, measurement visualization, and performance characterization together describe how quantum information is encoded, observed, interpreted, and evaluated within a quantum computing system. This research explores how qubit measurements collapse quantum states and how visualization tools help interpret these behaviors.

Quantum Computing and Visualization: A Disruptive Technological Change Ahead

E. Wes Bethel, Mercy G. Amankwah, J. T. Balewski +4 more

The focus of this Visualization Viewpoints article is to provide some background on quantum computing (QC), to explore ideas related to how visualization helps in understanding QC, and examine how QC might be useful for visualization with the growth and maturation of both technologies in the future. In a quickly evolving technology landscape, QC is emerging as a promising pathway to overcome the growth limits in classical computing. In some cases, QC platforms offer the potential to vastly outperform the familiar classical computer by solving problems more quickly or that may be intractable on any known classical platform. As further performance gains for classical computing platforms are limited by diminishing Moore's Law scaling, QC platforms might be viewed as a potential successor to the current field of exascale-class platforms. While present-day QC hardware platforms are still limited in scale, the field of quantum computing is robust and rapidly advancing in terms of hardware capabilities, software environments for developing quantum algorithms, and educational programs for training the next generation of scientists and engineers. After a brief introduction to QC concepts, the focus of this article is to explore the interplay between the fields of visualization and QC. First, visualization has played a role in QC by providing the means to show representations of the quantum state of single-qubits in superposition states and multiple-qubits in entangled states. Second, there are a number of ways in which the field of visual data exploration and analysis may potentially benefit from this disruptive new technology though there are challenges going forward.

Visual Analytics of Performance of Quantum Computing Systems and Circuit Optimization

Junghoon Chae, Chad A. Steed, Travis S. Humble

Driven by potential exponential speedups in business, security, and scientific scenarios, interest in quantum computing is surging. This interest feeds the development of quantum computing hardware, but several challenges arise in optimizing application performance for hardware metrics (e.g., qubit coherence and gate fidelity). In this work, we describe a visual analytics approach for analyzing the performance properties of quantum devices and quantum circuit optimization. Our approach allows users to explore spatial and temporal patterns in quantum device performance data and it computes similarities and variances in key performance metrics. Detailed analysis of the error properties characterizing individual qubits is also supported. We also describe a method for visualizing the optimization of quantum circuits. The resulting visualization tool allows researchers to design more efficient quantum algorithms and applications by increasing the interpretability of quantum computations.

Quantum Computing Models for Information Processing: A Comprehensive Study

Sulochana Sonkamble, Balwant A. Sonkamble

AbstractThe quantum computing has been proven to provide the solutions to most complex computations in the world today. Quantum computers can solve the problems with polynomial resources. Quantum information can be encoded in a number of ways, such as spin components of basic particles like photons, electrons, and polarization of photons. The quantum computer uses quantum bits which are superposition of states called as qubits, which is the classical fundamental unit of information. A quantum computer is a regular classical computer with additional ability to control the quantum bits. It is a regular computer connected to a special peripherals and a set of quantum bits simulated to build controller architecture. Two simulators are used for the quantum programming, one is Microsoft Q# and other is IBM Qiskit. Classical language Q # is used to program the quantum controller and its operations such that initializing a qubit, applying a gate on a qubit and measuring a qubit. IBM Qiskit programs simulates the functionality of quantum circuit and creates it’s drawing using a graphical interface with qubits, gates, and measurements. Qiskit provides simulators that run quantum circuits using visualization tools that help to understand the effect of our quantum circuits on the quantum states. The teleportation technique allows the quantum information to be communicated at a distance. An unbreakable encryption protocol is built for polarizing photons through the quantum channel. The combination of quantum computing and AI has the potential to drive significant advances across many sectors.

Simulation and Analysis of Bell States via Qiskit Quantum Circuits

Mounaim Hamdoune, Mohammed Daoud A

Abstract The visualization of qubit states plays a fundamental role in understanding quantum information processing. This study explores the use of the Bloch sphere as a geometrical tool for representing and interpreting single-qubit and two-qubit states. Using the Qiskit framework, we simulate quantum circuits to demonstrate the action of quantum gates and the generation of entangled states, such as Bell states. The effects of various gate operations on qubit orientation are analyzed in the Bloch sphere representation. Furthermore, we examine the matrix formalism of quantum states and provide a statistical analysis of measurement outcomes. This work bridges the gap between theoretical quantum mechanics and experimental simulation, offering insights for both educational and research purposes in quantum computing.

Manisha Prajapat, Kamal Kishor Choure, Gausia Qazi +2 more

The field of quantum computing is currently in its nascent stage and relies on the fundamental characteristics of quantum physics and the principles governing classical systems. This paves the way for the development of systems capable of solving intricate issues beyond classical systems’ capabilities. In this paper, 3-qubit entangled states are implemented using the Qiskit platform and analyzed by evaluating their probability graph and counts. The analysis of the entangled states in this paper may be helpful in implementing a quantum teleportation circuit in the near future.
