Exceptional-point braiding with native controls
Vishnu Chavva, Nero Osmancevic, Hugo Ribeiro
Exceptional points define branch-exchange state transfers through holomorphic continuation of non-Hermitian eigenmodes, but realizing these transfers dynamically remains difficult.…
Precise estimation of the coupling strength between two nanomechanical modes from four Ramsey fringes
Anh Tuan Le, Avishek Chowdhury, Hugo Ribeiro +1
We experimentally determine the coupling strength between two strongly coupled nanomechanical modes using a Ramsey-inspired technique optimized for signals as short as four fringes…
High-Flux Entangled Photon Generation via Clinical Megavoltage Radiotherapy Beams for Quantum Imaging and Theranostics
Gustavo Olivera, Bashkim Ziberi, Stephen Avery +4
Traditional sources of quantum-entangled photons, such as spontaneous parametric down-conversion, suffer from low flux, limiting clinical applications. We investigated whether clin…
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…
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…
Iterative Adaptive Spectroscopy of Short Signals
Avishek Chowdhury, Anh Tuan Le, Eva M. Weig +1
We develop an iterative, adaptive frequency sensing protocol based on Ramsey interferometry of a two-level system. Our scheme allows one to estimate unknown frequencies with a high…
Speeding up adiabatic quantum state transfer by using dressed states
Alexandre Baksic, Hugo Ribeiro, Aashish A. Clerk
We develop new pulse schemes to significantly speed up adiabatic state transfer protocols. Our general strategy involves adding corrections to an initial control Hamiltonian which…
