Verifying Heisenberg's error-disturbance relation using a single trapped ion.

ABSTRACT: Heisenberg's uncertainty relations have played an essential role in quantum physics since its very beginning. The uncertainty relations in the modern quantum formalism have become a fundamental limitation on the joint measurements of general quantum mechanical observables, going much beyond the original discussion of the trade-off between knowing a particle's position and momentum. Recently, the uncertainty relations have generated a considerable amount of lively debate as a result of the new inequalities proposed as extensions of the original uncertainty relations. We report an experimental test of one of the new Heisenberg's uncertainty relations using a single ⁴⁰Ca⁺ ion trapped in a harmonic potential. By performing unitary operations under carrier transitions, we
