Thermal Throttling of Quantum State Transfer
Twesh Upadhyaya, T. C. Mooney, Yifan Hong +1
Quantum state transfer on qubit lattices is a crucial step in a panoply of quantum information processing tasks. Understanding its fundamental limits in the presence of practical i…
Butterfly Echo Protocol for Axis-Agnostic Heisenberg-Limited Metrology
Jacob Bringewatt, Leon Zaporski, Matthew Radzihovsky +4
The extreme sensitivity of chaotic systems to external perturbations makes them natural candidates for sensing applications. We propose a single-shot echo-based protocol for estima…
On the Multi-Dimensional Divergence-Curl Problem and Its Connection with Pseudo-Harmonic Fields
A. V. Gorshkov
This article addresses the solvability of the multi-dimensional divergence-curl problem with a no-slip boundary condition. A solvability criterion is derived as an orthogonality co…
Multimode Strong-Coupling Processes in Circuit QED Lattices
Won Chan Lee, Ali Fahimniya, Kellen O'Brien +5
Circuit QED systems provide an ideal platform for exploring the strong-coupling regime of multimode cavity QED. Here we present two new phenomena from multimode strong coupling: a…
Unconventional entanglement scaling and quantum criticality in the long-range spin-one Heisenberg chain with single-ion anisotropy
Patrick Adelhardt, Sean R. Muleady, Kai P. Schmidt +1
Long-range interactions can fundamentally reshape the low-energy properties of low-dimensional quantum matter, altering both continuous symmetry breaking and topological phenomena.…
Robustness-Runtime Tradeoff for Quantum State Transfer
Twesh Upadhyaya, Yifan Hong, T. C. Mooney +1
Quantum state transfer is the primitive of transporting an unknown state on one site of a lattice to another. Using power-law interactions, recent state transfer protocols achieve…
