Abstract
Section titled āAbstractāNitrogen-vacancy centers in diamond, being a promising candidate for quantum\ninformation processing, may also be an ideal platform for simulating many-body\nphysics. However, it is difficult to realize interactions between\nnitrogen-vacancy centers strong enough to form a macroscopically ordered phase\nunder realistic temperatures. Here we propose a scheme to realize long-range\nferromagnetic Ising interactions between distant nitrogen-vacancy centers by\nusing a mechanical resonator as a medium. Since the critical temperature in the\nlong-range Ising model is proportional to the number of spins, a ferromagnetic\norder can be formed at a temperature of tens of millikelvin for a sample with\n$\sim10^4$ nitrogen-vacancy centers. This method may provide a new platform for\nstudying many-body physics using qubit systems.\n
