摘要
In this note, we first derive a Schodinger uncertainty relation for any pair of quaternionic observables and a mixed state. Then, the Wigner-Yanase skew information is introduced in the quaternion setting. Based on the skew information, we establish a new quantum uncertainty inequality for the non-Hermitian quaternionic observables.
