Query: Stochastic Qubits   A new concept of qubits is given by considering entanglement of ordinary
quibits with quantum measuring devices (micro-detectors). They are called
stochastic qubits since they are generalized coherent states used in the
stochastic (phase space) quantum theory. Entanglement is realized through the
coupling of angular momenta $l$ and $\sigma$, where the micro-detector has
$l=0,1$ and the qubit spin is $\sigma=1/2$. In both cases, the stochastic qubit
has total spin $J=1/2$ and is entangled only when $l=1$. In this case,
Stochastic Bell states have been defined and teleportation has been studied.
They resemble conventional ones. When the micro-detecors have only two states,
Stochastic qudits have rather been used. Here, Stochastic Bell states have also
been defined and teleportation is possible for special states only. In the last
step of this teleportation, Bob will have to transform the qubit only, or the
micro-detector only, to recover Alice state.
