... momentum, but it cannot carry a force. A force is exerted by one object on another object. So a single object can't carry a force. But we intuit that a moving bumper car carries some physical quantity of motion with it, some capacity to make other objects move in the direction of its motion. That ...

Spins in few-electron quantum dots
... The canonical example of a quantum-mechanical two-level system is spin. The simplest picture of spin is a magnetic moment pointing up or down. The full quantum properties of spin become apparent in phenomena such as superpositions of spin states, entanglement among spins, and quantum measurements. M ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
