Consider the density operator for the system of two spin-1/2 particles, where s) is the singlet state. a) construct the density matrix. b) find values of α at which this density matrix satisfies the coherence criterion for c) evaluate the concurrence for this density matrix, find a at which entanglement de- d) write down the reduced density matrix and evaluate the conditional entropy.

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
