摘要：The Heisenberg uncertainty relation for measurement noise and disturbance states that any position measurement with noise ε brings the momentum disturbance not less than hbar⁄2ε. However, this relation holds only for restricted class of measurements. Here, we discuss universally valid uncertainty relations for measurement noise and disturbance, which hold for all the possible quantum measurements.
