Self-consistency of the two-point energy measurement protocol
@article{Mohammady2020SelfconsistencyOT, title={Self-consistency of the two-point energy measurement protocol}, author={M. Hamed Mohammady}, journal={arXiv: Quantum Physics}, year={2020} }
The Two-Point energy Measurement (TPM) protocol defines the work done on a system undergoing unitary evolution as the difference in energy measurement outcomes performed before and after such evolution. By noting that energy measurements on the system can be modelled as a unitary premeasurement interaction between the system and a measurement apparatus, followed by measurement of the apparatus by a pointer observable, we show that it is possible to design a measurement scheme for the TPM…

The measurement of a quantum system is not consummated until irreversible processes have destroyed all phase coherence between different possible outcomes of that measurement. It is inconsistent to…
Ideal Projective Measurements Have Infinite Resource Costs
- Computer ScienceQuantum
- 2020
It is shown that it is impossible to perform ideal projective measurements on quantum systems using finite resources, and protocols for achieving optimal correlation given finite resources are provided for the most general system and pointer Hamiltonians.

Quantum Jarzynski Equality in Open Quantum Systems from the One-Time Measurement Scheme.
- PhysicsPhysical review letters
- 2020
A modified quantum Jarzynski equality and the principle of maximum work with respect to the guessed quantum work are derived by exploiting the one-time measurement scheme, which only requires an initial energy measurement on the system alone.

Concepts of work in autonomous quantum heat engines
- PhysicsQuantum
- 2019
This work analyzes work quantifiers for a heat-pumped three-level maser and derives the respective engine efficiencies, finding that in the classical limit of strong maser intensities the engine efficiency converges towards the Scovil--Schulz-DuBois maser efficiency, irrespective of the work quantifier.
Conditional work statistics of quantum measurements

In this paper we introduce a definition for conditional energy changes due to general quantum measurements, as the change in the conditional energy evaluated before, and after, the measurement…
