Most computers today are based on “bits”: namely, 0 and 1. Complicated computations can often be reduced to operations on bits, which can be performed efficiently by these computers. Indeed, exponential growth over recent decades in computational power have fueled progress in fields ranging from basic science to medicine, artificial intelligence and communication. However, many important computations remain out of reach of such computers. There is growing optimism that some of these hard problems may be successfully solved using a different computational paradigm, which is based instead on “qubits”: roughly speaking, combinations of 0 and 1, of which there are infinitely many possibilities. Remarkably, qubits can be realized in Nature; and primitive computers that operate on qubits, called quantum computers, are already available. After reviewing these developments, I will focus on the problem of simulating systems that obey the laws of quantum mechanics, for which quantum computers could play an important role.
