## Pesach Sheini – in a State of Superposition

In physics, we speak of systems and states. A system is a collection of physical objects (particles, waves, etc.). A system can be in various states. For example, a coin could have two states—heads or tails. A top also has two possible states—it can be spinning clockwise or counterclockwise. Light can have two states as well—being in the vertical polarization or horizontal polarization. In classical mechanics, a system can only be in a single state, i.e., at any given point in time, a coin can be either in a state “Heads” or in the alternative state “Tales”. A top can either be spinning clockwise or counterclockwise. In quantum mechanics, a system can also be in a state of superposition. Let us say, the system has two possible states A and B. If a [...]
