Relative quantum complexity is the measure of state distance between two quantum states. In quantum circuits, it could be argued as the number of fundamental quantum logic gates required to change the initial state of a quantum system to another state. From the Penrose diagrams of Ads/CFT black holes, it has been analyzed that the volume of black holes increases with time. The astounding similarity between the growth of quantum complexity and the volume of black holes is believed to be the fundamental postulate to quantize gravity. Here, we implement a simulation model to demonstrate the power of one clean qubit. We explicate how addition of one clean qubit could increase the uncomplexity of a maximally complex state. We explore the clean qubit computation in IBM quantum experience platform by designing the circuits and running them on IBM QASM simulator. This one clean qubit computation is realized for maximally complex five states made of single-, two-, three-, four-, and five-qubit systems and the results are discussed by comparing the power of one thermal photon on the accessible spacetime of an observer near the black hole horizon.

poster

The Institute of Physics and IOP Publishing, in partnership with the Chinese Physical Society (CPS) and the University of Science and Technology of China (USTC) are proud to have brought together the international quantum science community online for this inaugural conference.


Early career and leading researchers from universities, industry and government worldwide came together to share, learn and collaborate on the latest research and emerging areas of high interest across quantum science and technology. The broad themes covered by Quantum 2020 included:

Quantum communication;
Quantum computing and quantum simulation;
Quantum sensing, metrology and imaging;
Quantum information theory, software and algorithms;
Quantum foundations;
Quantum technology in industry.
The four-day event featured talks from world-renowned scientists, interactive poster sessions and two exciting panel discussions on the themes of Quantum Technology in Industry and Quantum Technology Programmes Around the World.
