Abstract
We present quantum versions of the Jarzynski equality for the energy costs of information processes, namely the measurement and the information erasure. We also obtain inequalities for the energy costs of the information processes, using the Jensen inequality. The inequalities include Sagawa and Ueda's inequalities [Phys. Rev. Lett. 102, 250602 (2009)] as a special case.
