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 by many,
the first realisation of quantum computing technology would occur over the
cloud, with users logging onto dedicated hardware over the classical internet.
Recently IBM has released the {\em 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 that have never been demonstrated before. We utilise
the IBM chip to realise 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 development in
quantum information technology.

该论文介绍了利用基于 IBM Quantum Experience 的在线可用的真实量子硬件实现四种前所未有的量子信息实验的实验结果，包括量子纠错、量子算术、量子图论和容错量子计算，该结果表明实验组向更广泛的受众开放其技术的强大力量并有望推动量子信息技术的下一阶段发展。
