The ultimate photon detector, however, is not yet at hand some challenges remain for Day and colleagues design 4: for example although there is very little noise in the readout system the detector itself has not yet achieved that low level of noise Whether the noise source is intrinsic or extrinsic is not clear, but i am optim istic that it can be remedied. Meanwhile, in the race to produce the ultimate photon detector, the other candidates (mentioned above) are advancing the winner winners -of this race will be determined in part by issues that go beyond performance, such as cost and ease of use. Practical eng ineering factors hold sway in astronomy just as in regular life. References 1 Day, P K, LeDuc, H G, Mazin, B A, Vayonakis, A&Zmuidzinas, J. Nature 425, 817-821 (2003).| Artic 2.
