Quantum physics, or quantum mechanics, is a scientific field focused on the behavior of subatomic particles. It is notoriously arcane, using math to describe phenomena that run counter to common-sense assumptions. Particles, for instance, can exist in a state of “superposition,” where such properties as location or speed are defined by a probability distribution rather than a single, definite number.
To illustrate that point, much popular-level writing about quantum mechanics has invoked “Schrödinger's cat,” an imaginary scenario (discussed by physicist Erwin Schrödinger in the 1930s) in which a cat in a box supposedly can be both dead and alive, since its fate was determined by a particle process that yielded only probabilities.
Contrary to the impression one might get from reading some popular treatments, however, most physicists are not inclined to believe in dead-and-alive cats. Rather, they see superposition as a delicate state that is difficult to maintain in systems involving numerous particles (and effectively impossible in a large, active object such as a cat).
Such matters might seem far removed from the everyday concerns of financial advisors. But actually, quantum mechanics may end up being a subject of pressing importance in the advice industry. Whether that is the case depends on what happens with quantum computing, a technology that is now in its infancy but which—if its proponents’ ambitious visions are on target—could reshape finance and much else.Read the full article: "Can Advisors Handle Quantum Computers?"
