Quantum-enhanced sensing of displacements and electric fields with large trapped-ion crystals

August 6, 2021
Author(s)
Kevin Gilmore, Matthew Affolter, Judith Jordan, Diego Barberena, Robert Lewis-Swan, Ana Maria Rey, John J. Bollinger
Developing the isolation and control of ultracold atomic systems to the level of single quanta has led to significant advances in quantum sensing, yet demonstrating a quantum advantage in real world applications by harnessing entanglement remains a core

Resource-efficient dissipative entanglement of two trapped-ion qubits

August 6, 2021
Author(s)
Daniel Cole, Stephen Erickson, Giorgio Zarantonello, Panyu Hou, Jenny Wu, Karl Horn, Daniel Slichter, Florentin Reiter, Christiane Koch, Dietrich Leibfried
We demonstrate a simplified method for generating an entangled state of two trapped-ion qubits. Our implementation produces its target state faster and with higher fidelity than previous demonstrations of dissipative entanglement generation, while

Spin Reorientation in Antiferromagnetic Layered FePt5P

July 30, 2021
Author(s)
Xin Gui, Madalynn Marshall, Ranuri Dissanayaka Mudiyanselage, Ryan Klein, Qiang Chen, Qiang Zhang, William Shelton, Haidong Zhou, Craig Brown, Huibo Cao, Martha Greenblatt, Weiwei Xie
FePt5P, a new substitutional variant of the CeCoIn5 structure type in space group P4/mmm, was synthesized by high-temperature solid-state method and structurally characterized by X-ray diffraction. FePt5P contains layers of FePt12 clusters formed by

Integrated superconducting nanowire single-photon detectors on titanium in-diffused lithium niobate waveguides

July 28, 2021
Author(s)
Varun Verma, Richard Mirin, Sae Woo Nam, Jan P. Hoepker, Maximilian Protte, Raimund Ricken, Victor Quiring, Christof Eigner, Christine Silberhorn, Tim J. Bartley
We demonstrate the integration of amorphous tungsten silicide superconducting nanowire single- photon detectors on titanium in-diffused lithium niobate waveguides. We show proof-of-principle detection of evanescently-coupled photons of wavelength 1550nm

A System for Validating Resistive Neural Network Prototypes

July 27, 2021
Author(s)
Brian Hoskins, Mitchell Fream, Matthew Daniels, Jonathan Goodwill, Advait Madhavan, Jabez J. McClelland, Osama Yousuf, Gina C. Adam, Wen Ma, Muqing Liu, Rasmus Madsen, Martin Lueker-Boden
Building prototypes of heterogeneous hardware systems based on emerging electronic, magnetic, and photonic devices is an increasingly important area of research. On the face of it, the novel implementation of these systems, especially for online learning

De-excitation dynamics of muonic atoms revealed by high precision spectroscopy of electronic K x rays using a superconducting transition-edge sensor microcalorimeter

July 27, 2021
Author(s)
Douglas Bennett, W.Bertrand (Randy) Doriese, Malcolm Durkin, Joseph Fowler, Johnathon Gard, Gene C. Hilton, Kelsey Morgan, Galen O'Neil, Carl D. Reintsema, Dan Schmidt, Daniel Swetz, Joel Ullom, Toshiyuki Azuma, Pietro Caradonna, I-Huan Chiu, Tadashi Hashimoto, Ryota Hayakawa, Yuto Ichinohe, Paul Indelicato, TadaAki Isobe, Sohtaro Kanda, Daiji Kato, Miho Katsuragawa, Naritoshi Kawamura, Yasushi Kino, Kenya Kubo, Kairi Mine, Yasuhiro Miyake, Kazuhiko Ninomiya, Hirofumi Noda, Shinji Okada, Takuma Okumura, Kenichi Okutsu, Takahito Osawa, Nancy Paul, Kouichiro Shimomura, Patrick Strasser, Hirotaka Suda, Tadayuki Takahashi, Shinichiro Takeda, Soshi Takeshita, Motonobu Tampo, Hideyuki Tatsuno, XiaoMin Tong, Yasuhiro Ueno, Shin Watanabe, Shinya Yamada
We observed electronic K x rays emitted from muonic iron atoms using a superconducting transition-edge-type sensor microcalorimeter. The energy resolution of 5.2 eV in FWHM allowed us to observe the asymmetric broad profile of the electronic characteristic

Programmable System on Chip for controlling an atomic physics experiment

July 23, 2021
Author(s)
Ananya Sitaram, Gretchen K. Campbell, Alessandro Restelli
Most atomic physics experiments are controlled by a digital pattern generator used to synchronize all equipment by providing triggers and clocks. Recently, the availability of well-documented open-source development tools has lifted the barriers to using
