Explainable Classification Techniques for Quantum Dot Device Measurements

March 12, 2024
Author(s)
Daniel Schug, Tyler Kovach, Jared Benson, Mark Eriksson, Justyna Zwolak
In the physical sciences, there is an increased need for robust feature representations of image data: image acquisition, in the generalized sense of two-dimensional data, is now widespread across a large number of fields, including quantum information

Logical quantum processor based on reconfigurable atom arrays

December 6, 2023
Author(s)
Dolev Bluvstein, Simon Evered, Alexandra Geim, Sophie Li, Hengyun Zhou, Tom Manovitz, Sepehr Ebadi, Madelyn Cain, Marcin Kalinowski, Dominik Hangleiter, J. Pablo Bonilla Ataides, Nishad Maskara, Iris Cong, Xun Gao, Pedro Rodriguez, Thomas Karolyshyn, Giulia Semeghini, Michael Gullans, Markus Greiner, Vladan Vuletic, Mikahil Lukin
Suppressing errors is the central challenge for useful quantum computing and quantum error correction is believed to be the key to large-scale quantum processing. Here we report the realization of a programmable quantum processor based on encoded logical

Telecom band quantum dot technologies for long-distance quantum networks

December 4, 2023
Author(s)
Ying Yu, Changmin Lee, Peter Michler, Stephan Reitzenstein, Kartik Srinivasan, Edo Waks, Shunfa Liu, Jin Liu
A future quantum internet is expected to generate, distribute, store and process quantum bits (qubits) over the world by linking different quantum nodes via quantum states of light. To facilitate long-haul operations, quantum repeaters must operate at

Direct-Laser-Written Polymer Nanowire Waveguides for Broadband Single Photon Collection from Epitaxial Quantum Dots into a Gaussian-like Mode

November 16, 2023
Author(s)
Edgar Perez, Cori Haws, Marcelo Davanco, Jindong Song, Luca Sapienza, Kartik Srinivasan
Single epitaxial quantum dots (QDs) are a leading technology for quantum light generation, particularly when they are embedded in photonic geometries that enhance their emission into a targeted and confined mode. However, coupling this mode into a

Clifford operations and homological codes for rotors and oscillators

November 14, 2023
Author(s)
Yijia Xu, Yixu Wang, Victor Albert
We develop quantum information processing primitives for the planar rotor, the state space of a particle on a circle. By interpreting rotor wavefunctions as periodically identified wavefunctions of a harmonic oscillator, we determine the group of bosonic

Grain size in low loss superconducting Ta thin films on c-axis sapphire

October 9, 2023
Author(s)
Corey Rae McRae
In recent years, the implementation of thin-film Ta has led to improved coherence times in superconducting circuits. Efforts to further optimize this materials stack have become a focus of the materials for superconducting quantum computing subfield. It

Suppressing communication errors using quantum-enabled forward error correction

September 28, 2023
Author(s)
Ivan Burenkov, FNU Nur Fajar Rizqi Annafianto, Jabir Marakkarakath Vadakkepurayil, Abdella Battou, Sergey Polyakov
Scalable optical communication requires error identification and correction to protect and recover information from channel and detection noise. Forward error correction protects information transmitted with optical pulses by amending errors using

Tuning Arrays with Rays: Physics-Informed Tuning of Quantum Dot Charge States

September 28, 2023
Author(s)
Joshua Ziegler, Florian Luthi, Mick Ramsey, Felix Borjans, Guoji Zheng, Justyna Zwolak
Quantum computers based on gate-defined quantum dots (QDs) are expected to scale. However, as the number of qubits increases, the burden of manually calibrating these systems becomes unreasonable and autonomous tuning must be used. There has been a range

Comparison of the detection efficiency calibration of a single-photon avalanche detector between NIST and PTB

September 12, 2023
Author(s)
Hristina Georgieva, Thomas Gerrits, Helmuth Hofer, Anouar Rahmouni, Oliver T. Slattery, Marco Lopez, Joshua Bienfang, Alan Migdall, Stefan Kueck
The detection efficiency of a commercial single-photon avalanche detector (SPAD) has been independently determined at two national metrology institutes, the National Institute of Standards and Technology (NIST) - USA and the Physikalisch-Technische

Single-photon Sources and Detectors Dictionary

September 7, 2023
Author(s)
Joshua Bienfang, Thomas Gerrits, Paulina Kuo, Alan Migdall, Sergey Polyakov, Oliver T. Slattery
The intention of this dictionary is to define relevant terms and metrics used in the characterization of single-photon detectors and sources with the goal to promote better understanding and communication of those metrics across the single-photon
