Improved quantum sensing with a single solid-state spin via spin-to-charge conversion

Jean-Christophe Jaskula, Brendan J. Shields, Erik Bauch +3

Efficient optical readout of a single, solid-state electronic spin at room temperature is a key challenge for nanoscale quantum sensing. Here we apply the technique of spin-to-char…

Quantum information in the Posner model of quantum cognition

Nicole Yunger Halpern, Elizabeth Crosson

Matthew Fisher recently postulated a mechanism by which quantum phenomena could influence cognition: Phosphorus nuclear spins may resist decoherence for long times, especially when…

Electronic structure of ultralong-range Rydberg pentaatomic molecules with two polar diatomic molecules

Javier Aguilera-Fernández, H. R. Sadeghpour, Peter Schmelcher +1

We explore the electronic structure of ultralong-range pentaatomic Rydberg molecules from a merger of a Rydberg atom and two ground state heteronuclear diatomic molecules. Our focu…

Photonic Band Structure of Two-dimensional Atomic Lattices

Janos Perczel, Johannes Borregaard, Darrick E. Chang +4

Two-dimensional atomic arrays exhibit a number of intriguing quantum optical phenomena, including subradiance, nearly perfect reflection of radiation and long-lived topological edg…

Bell's Theorem for Temporal Order

Magdalena Zych, Fabio Costa, Igor Pikovski +1

Time has a fundamentally different character in quantum mechanics and in general relativity. In quantum theory events unfold in a fixed time order while in general relativity tempo…

Micrometer-scale Magnetic Imaging of Geological Samples Using a Quantum Diamond Microscope

David R. Glenn, Roger R. Fu, Pauli Kehayias +4

Remanent magnetization in geological samples may record the past intensity and direction of planetary magnetic fields. Traditionally, this magnetization is analyzed through measure…

High Resolution Magnetic Resonance Spectroscopy Using Solid-State Spins

Dominik B. Bucher, David R. Glenn, Junghyun Lee +3

We demonstrate a synchronized readout (SR) technique for spectrally selective detection of oscillating magnetic fields with sub-millihertz resolution, using coherent manipulation o…

Delayed Coherent Quantum Feedback from a Scattering Theory and a Matrix Product State Perspective

Pierre-Olivier Guimond, Mikhail Pletyukhov, Hannes Pichler +1

We study the scattering of photons propagating in a semi-infinite waveguide terminated by a mirror and interacting with a quantum emitter. This paradigm constitutes an example of c…

Creation of Rydberg Polarons in a Bose Gas

F. Camargo, R. Schmidt, J. D. Whalen +8

We report spectroscopic observation of Rydberg polarons in an atomic Bose gas. Polarons are created by excitation of Rydberg atoms as impurities in a strontium Bose-Einstein conden…

Quantum Spin Lenses in Atomic Arrays

A. W. Glaetzle, K. Ender, D. S. Wild +4

We propose and discuss `quantum spin lenses', where quantum states of delocalized spin excitations in an atomic medium are `focused' in space in a coherent quantum process down to…

Topological Quantum Optics in Two-Dimensional Atomic Arrays

Janos Perczel, Johannes Borregaard, Darrick E. Chang +4

We demonstrate that two-dimensional atomic emitter arrays with subwavelength spacing constitute topologically protected quantum optical systems where the photon propagation is robu…

Photonic tensor networks produced by a single quantum emitter

Hannes Pichler, Soonwon Choi, Peter Zoller +1

We propose and analyze a protocol to generate two dimensional tensor network states using a single quantum system that sequentially interacts with a 1D string of qubits. This is ac…
