Topological Operations Around Exceptional Points via Shortcuts to Adiabaticity
Vishnu Chavva, Hugo Ribeiro
The existence of singularities in the spectrum of non-Hermitian Hamiltonians leads to a non-trivial spectral topology which can be exploited to generate topological operations. How…
Quantifying spectral signatures of non-Markovianity beyond the Born-Redfield master equation
A. Keefe, N. Agarwal, A. Kamal
Memory or time-non-local effects in open quantum dynamics pose theoretical as well as practical challenges in the understanding and control of noisy quantum systems. While there ha…
Reservoir Engineering for Classical Nonlinear Fields
Benedikt Tissot, Hugo Ribeiro, Florian Marquardt
Reservoir engineering has become a prominent tool to control quantum systems. Recently, there have been first experiments applying it to many-body systems, especially with a view t…
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…
Modular tunable coupler for superconducting qubits
Daniel L. Campbell, Archana Kamal, Leonardo Ranzani +2
The development of modular and versatile quantum interconnect hardware is a key next step in the scaling of quantum information platforms to larger size and greater functionality.…
