The Teleportation of the Bell States Has Been Carried Out on the Five-Qubit Quantum IBM Computer

Abstract

Abstract In this paper, we present and compare via the computational experiments two distinct realizations of a protocol of two-qubit state teleportation. Our first achievement has been accomplished on the IBM Q quantum computer available for use through the IBM Q Experience online platform and the Qiskit open-source quantum software development kit, which forms a virtual interface for the quantum computer. Our second realization uses the Feynman, classical simulator of quantum computation written in Maple, the user’s language of the computer algebra system. Our experiments with the IBM Q Experience show that the error rate increase, caused by the distortion of quantum states in the course of computing, requires quantum error correction or the technological improvement of quantum hardware to decrease the error rate.

First Realization of Quantum Energy Teleportation on Quantum Hardware

Kazuki Ikeda

Abstract Teleporting physical quantities to remote locations is a remaining key challenge for quantum information science and technology. Quantum teleportation has enabled the transfer of quantum information, but teleportation of quantum physical quantities has not yet been realized. Here we report the first realization and observation of quantum energy teleportation on real quantum hardware. We achieve this by using several IBM’s superconducting quantum computers. The results are consistent with the exact solution of the theory and are improved by the mitigation of measurement error. Quantum energy teleportation requires only local operations and classical communication. Therefore our results provide a realistic benchmark that is fully achievable with current quantum computing and communication technologies.

Experimental simulation of hybrid quantum systems and entanglement on a quantum computer

Farai Mazhandu, Kayleigh Mathieson, Christopher Coleman +1 more

We propose the utilization of the IBM Quantum Experience quantum computing system to simulate different scenarios involving common hybrid quantum system components, the nitrogen vacancy center (NV center), and the flux qubit. We perform a series of simulation experiments and demonstrate properties of a virtual hybrid system, including its spin relaxation rate and state coherence. In correspondence with experimental investigations, we look at the scalability of such systems and show that increasing the number of coupled NV centers decreases the coherence time. We also establish the main error rate as a function of the number of control pulses in evaluating the fidelity of the four qubit virtual circuit with the simulator. Our results show that the virtual system can attain decoherence and fidelity values comparable to what has been reported for experimental investigations of similar physical hybrid systems, observing a coherence time at 0.35 s for a single NV center qubit and fidelity in the range of 0.82. This work thus establishes an effective simulation protocol to test and evaluate different technologies as a supplementary measure that complements their experimental operation.

Performing quantum computing experiments in the cloud

Simon J. Devitt

Quantum computing technology has reached a second renaissance in the past five years. Increased interest from both the private and public sector combined with extraordinary theoretical and experimental progress has solidified this technology as a major advancement in the 21st century. As anticipated my many, some of the first realizations of quantum computing technology has occured over the cloud, with users logging onto dedicated hardware over the classical internet. Recently, IBM has released the Quantum Experience, which allows users to access a five-qubit quantum processor. In this paper we take advantage of this online availability of actual quantum hardware and present four quantum information experiments. We utilize the IBM chip to realize protocols in quantum error correction, quantum arithmetic, quantum graph theory, and fault-tolerant quantum computation by accessing the device remotely through the cloud. While the results are subject to significant noise, the correct results are returned from the chip. This demonstrates the power of experimental groups opening up their technology to a wider audience and will hopefully allow for the next stage of development in quantum information technology.

A quantum teleportation experiment for undergraduate students

S. Fedortchenko

With the rapid progress of quantum information these recent years, it becomes more and more relevant to dedicate efforts in introducing this research topic to undergraduate students. However, as if in various fields of physics the theoretical learning is closely accompanied with experimental illustrations, such a teaching method can be expensive to organise for quantum information. We propose one way to circumvent these difficulties by using the recently made available 5-qubit quantum processor of IBM, in order to illustrate quantum information tasks, by actually implementing them on the superconducting chip through the web interface of the IBM Quantum Experience. We focus on the realization of a quantum teleportation protocol on this device, analyze the results and discuss the issues encountered, providing a complete analysis of this software as a pedagogical tool.

On the Experimental Performance Measurement of Quantum Teleportation

Ved Dharkar, Suman Kumar

Quantum information system has a potential to revolutionize the way we think of computing and communication. Quantum Teleportation has emerged as a promising technique for transmitting quantum information securely over long distances between quantum computers. However, it is unclear how well this performs in a real world. This paper attempts to evaluate the performance of Quantum Teleportation on actual quantum computers. The impact of environmental factors such as number of qubits, number of gates and hardware configuration on the Quantum Teleportation is measured over IBM Superconducting Quantum Computers. The paper aims to illuminate the current state of Quantum Teleportation and the associated challenges in measuring its performance, particularly in the context of security within quantum communication.
