A quantum simulation of reality

Wanwan Li

As quantum computing theory is attracting attention from researchers nowadays, visualizing the quantum computing process is necessary for fundamental quantum computing education and research. Especially, connecting traditional computational theory with advanced quantum computing concepts is an extremely important step in learning and understanding quantum computing. In this paper, we propose a practical interactive interface for simulating Quantum Turing Machine (QTM) in Augmented Reality (AR) that combines the traditional Turing machine computational model with the quantum computing simulation. Through such an interface, users can use a C-like script to represent a QTM and simulate such QTM in an immersive augmented reality platform through the Vuforia AR engine. After validating our proposed QTM AR simulator through a series of experiments, we show the great potential to apply our QTM AR simulator to quantum computing education through an interactive visualization interface in augmented reality.

Quantum simulators are controllable quantum systems that can be used to simulate other quantum systems. Being able to tackle problems that are intractable on classical computers, quantum simulators would provide a means of exploring new physical phenomena. We present an overview of how quantum simulators may become a reality in the near future as the required technologies are now within reach. Quantum simulators, relying on the coherent control of neutral atoms, ions, photons, or electrons, would allow studying problems in various fields including condensed-matter physics, high-energy physics, cosmology, atomic physics, and quantum chemistry.

We improve on the results of [A. Jackson et al. Proc. Natl. Acad. Sci. U.S.A 121 (6). 2024] on the verification of analogue quantum simulators by eliminating the use of universal Hamiltonians, removing the need for two-qubit gates, and no longer assuming error is represented by identical maps across simulations. This new protocol better reflects the reality of extant analogue simulators. It integrates well with recent complexity theoretic results, leading to a near-term feasible simulation-based route to establishing quantum advantage.
