%X A new method is produced of directly measuring EPR beams. This measurement scheme can be used for measuring the correlation degree of EPR beams with correlated amplitude quadratures and anticorrelated phase quadratures without using local oscillators. Then a new scheme for quantum dense coding is proposed based on this measurement scheme.
