Researchers Simulate Quantum Systems Using Periodic Drives

Periodic control enables one quantum system to replicate another’s physical properties through a theory called ‘Floquet simulation’, employing periodically changing forces to synthesise systems equivalent to those governed by unchanging forces. Specific interactions accurately mimic any comparable Hamiltonian, requiring only a manageable number of interaction strengths and driving frequencies which scale predictably with system size, avoiding limitations found in traditional analogue simulations. A new method for quantum simulation utilises systems subjected to periodic forces, offering an alternative approach potentially more efficient than current techniques. Identifying ‘Floquet-universal’…
