  Although a precise description of microscopic physical problems requires a
full quantum mechanical treatment, physical quantities are generally discussed
in terms of classical variables. One exception is quantum entanglement which
apparently has no classical counterpart. We demonstrate here how quantum
entanglement may be within the de Broglie-Bohm interpretation of quantum
mechanics visualized in geometrical terms, giving new insight into this
mysterious phenomenon and a language to describe it. On the basis of our
analysis of the dynamics of a pair of qubits, quantum entanglement is linked to
concurrent motion of angular momenta in the Bohmian space of hidden variables
and to the average angle between these momenta.
