Researchers of the ELKH Wigner Research Centre for Physics (Wigner RCP) have developed a computer network service that is suitable for the software implementation of quantum and non-signaling correlations. Nonlocal Box Emulator, an API service (Application Programming Interface) which can also be used for simulation testing of quantum communication protocols, is a useful tool not only for researchers, but also for enthusiasts and experimental developers, and can contribute to the development of new applications and the discovery of additional usage possibilities. More information about the free service is available on the Wigner RCP website, where anyone can try it after registration.
The “second revolution” of quantum mechanics is primarily due to the phenomenon of quantum entanglement. The investigation of this, in addition to a deeper understanding of the fundamental questions of physics, led to the development of the technologies of quantum encryption and quantum computing. It is no coincidence that the 2022 Nobel Prize in Physics was also awarded for the experimental study of entanglement and non-classical correlations.
The new service of Wigner RCP implements quantum and also more general non-signaling correlations in software. With the help of encrypted communication with a central server, it can also emulate measurements on entangled quantum particles. The Nonlocal Box Emulator enables anyone to get to know and experiment with non-classical correlations, and can also serve as a basis for developing various software applications. The researchers hope that by making the service public, it can initiate a wide-ranging discussion that could shed light on new possibilities of use and contribute to the development of various applications.
In addition to the now available web service, Wigner RCP researchers also plan to develop a mobile application in the near future that will help to understand non-classical correlations in an experiential way.
