Ab. Matsko et al., QUANTUM-NONDEMOLITION DETECTION OF SINGLE PHOTONS IN AN OPEN RESONATOR BY ATOMIC-BEAM DEFLECTION, Physics letters. A, 192(2-4), 1994, pp. 175-179
We discuss a scheme to perform quantum nondemolition (QND) detection o
f single optical or millimeter-band photons by observing the deflectio
n of a beam of atoms flying close to an open dielectric resonator. Our
analytical calculations take account of spontaneous emission and reso
nator losses.
