Experimental demonstration of a classical analog to quantum noise cancellation for use in gravitational wave detection

Mow-Lowry, C; Sheard, B; Gray, Malcolm B; McClelland, David; Whitcomb, Stanley Ernest


We present results that are a classical analog to quantum noise cancellation. It is possible to breach the standard quantum limit in an interferometer by the use of squeezing to correlate orthogonal quadratures of quantum noise, causing their effects on the resulting sensitivity to cancel. A laser beam incident on a Fabry-Perot cavity was imprinted with classical, correlated noise in the same quadratures that cause shot noise and radiation pressure noise. Couplings between these quadratures due...[Show more]
