Stabilizing two-qubit entanglement with dynamically decoupled active feedback

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Sacha Greenfield, Leigh Martin, Felix Motzoi, K. Birgitta Whaley, Justin Dressel | Summary: We propose and analyze a protocol for stabilizing a maximally entangled state of two noninteracting qubits using active state-dependent feedback from a continuous two-qubit half-parity measurement in coordination with a concurrent, non-commuting dynamical decoupling […]

$textit{In situ}$ electric-field control of ferromagnetic resonance in the low-loss organic-based ferrimagnet V[TCNE]$_{xsim 2}$

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Seth W. Kurfman, Andrew Franson, Piyush Shah, Yueguang Shi, Hil Fung Harry Cheung | Summary: We demonstrate indirect electric-field control of ferromagnetic resonance (FMR) in devices that integrate the low-loss, molecule-based, room-temperature ferrimagnet vanadium tetracyanoethylene (V[TCNE]$_{x sim 2}$) mechanically coupled to PMN-PT piezoelectric transducers. Upon straining […]

Maximally-Localized Exciton Wannier Functions for Solids

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Jonah B. Haber, Diana Y. Qiu, Felipe H. da Jornada, Jeffrey B. Neaton, | Summary: We introduce a maximally-localized Wannier function representation of Bloch excitons, two-particle correlated electron-hole excitations, in crystalline solids, where the excitons are maximally-localized with respect to an average electron-hole coordinate in real […]

Bichromatic Rabi Control of Semiconductor Qubits

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Valentin John, Francesco Borsoi, Zoltán György, Chien-An Wang, Gábor Széchenyi | Summary: Electrically driven spin resonance is a powerful technique for controlling semiconductor spin qubits. However, it faces challenges in qubit addressability and off-resonance driving in larger systems. We demonstrate coherent bichromatic Rabi control of quantum dot […]

Lack of near-sightedness principle in non-Hermitian systems

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Helene Spring, Viktor Könye, Anton R. Akhmerov, Ion Cosma Fulga, | Summary: The non-Hermitian skin effect is a phenomenon in which an extensive number of states accumulates at the boundaries of a system. It has been associated to nontrivial topology, with nonzero bulk invariants predicting its […]
