Non-Ideal Measurement Heat Engines
Abhisek Panda, Felix C. Binder, Sai Vinjanampathy
We discuss the role of non-ideal measurements within the context of measurement engines by contrasting examples of measurement engines which have the same work output but with vary…
Shallow-Depth Variational Quantum Hypothesis Testing
Mahadevan Subramanian, Sai Vinjanampathy
We present a variational quantum algorithm for differentiating several hypotheses encoded as quantum channels. Both state preparation and measurement are simultaneously optimized u…
Synchronization Lower Bounds the Efficiency of Near-Degenerate Thermal Machines
Taufiq Murtadho, Juzar Thingna, Sai Vinjanampathy
We study the relationship between quantum synchronization and the thermodynamic performance of a four-level near-degenerate extension of the Scovil-Schulz Dubois thermal maser. We…
Cooperation and Competition in Synchronous Open Quantum Systems
Taufiq Murtadho, Sai Vinjanampathy, Juzar Thingna
Synchronization between limit cycle oscillators can arise through entrainment to an external drive or through mutual coupling. The interplay between the two mechanisms has been stu…
