Quantum error correction well below the color code threshold
Ali Lavasani, Adam P. Reed, Joan M. Dreiling +20
Quantum error correction enables scalable fault-tolerant quantum computation by suppressing logical errors exponentially with code distance once physical error rates fall below a c…
Computing with many encoded logical qubits beyond break-even
Shival Dasu, Matthew DeCross, Andrew Y. Guo +42
High-rate quantum error correcting (QEC) codes encode many logical qubits in a given number of physical qubits, making them promising candidates for quantum computation. Implementi…
A Room-Temperature Extreme High Vacuum System for Trapped-Ion Quantum Information Processing
Lewis Hahn, Nikhil Kotibhaskar, Fabien Lefebvre +4
We present a room-temperature Extreme High Vacuum (XHV) system engineered to support the long-duration operation of a trapped-ion quantum processor. Background-gas collisions impos…
Helios: A 98-qubit trapped-ion quantum computer
Anthony Ransford, M. S. Allman, Jake Arkinstall +183
We report on Quantinuum Helios, a 98-qubit trapped-ion quantum processor based on the quantum charge-coupled device (QCCD) architecture. Helios features Ba hyperfine…
Realization of a Quantum Streaming Algorithm on Long-lived Trapped-ion Qubits
Pradeep Niroula, Shouvanik Chakrabarti, Steven Kordonowy +30
Large classical datasets are often processed in the streaming model, with data arriving one item at a time. In this model, quantum algorithms have been shown to offer an unconditio…
Certified randomness amplification by dynamically probing remote random quantum states
Minzhao Liu, Pradeep Niroula, Matthew DeCross +49
Cryptography depends on truly unpredictable numbers, but physical sources emit biased or correlated bits. Quantum mechanics enables the amplification of imperfect randomness into n…
Superconducting pairing correlations on a trapped-ion quantum computer
Etienne Granet, Sheng-Hsuan Lin, Kevin Hémery +31
The Fermi-Hubbard model is the starting point for the simulation of many strongly correlated materials, including high-temperature superconductors, whose modelling is a key motivat…
Optical field characterization at the fundamental limit of spatial resolution with a trapped ion
Nikhil Kotibhaskar, Sainath Motlakunta, Anthony Vogliano +2
Optical systems capable of generating fields with sub-wavelength spatial features have become standard in science and engineering research and industry. Pertinent examples include…
Digital quantum magnetism on a trapped-ion quantum computer
Reza Haghshenas, Eli Chertkov, Michael Mills +56
Digital quantum matter -- realized when discrete quantum gates approximate continuous time evolution -- is susceptible to heating into chaotic, structureless states. If digitizatio…
Programmable XY-type couplings through parallel spin-dependent forces on the same trapped ion motional modes
Nikhil Kotibhaskar, Chung-You Shih, Sainath Motlakunta +4
We propose and experimentally demonstrate an analog scheme for generating XY-type ( + ) Hamiltonians on trapped ion spins with ind…
Preserving a qubit during adjacent measurements at a few micrometers distance
Sainath Motlakunta, Nikhil Kotibhaskar, Chung-You Shih +6
Protecting a quantum object against irreversible accidental measurements from its surroundings is necessary for controlled quantum operations. This becomes especially challenging o…
Fast and high-yield fabrication of axially symmetric ion-trap needle electrodes via two step electrochemical etching
Nikhil Kotibhaskar, Noah Greenberg, Sainath Motlakunta +2
Despite the progress in building sophisticated microfabricated ion traps, Paul traps employing needle electrodes retain their significance due to the simplicity of fabrication whil…
Dynamic Hamiltonian engineering of 2D rectangular lattices in a one-dimensional ion chain
Fereshteh Rajabi, Sainath Motlakunta, Chung-You Shih +4
Controlling the interaction graph between spins or qubits in a quantum simulator allows user-controlled tailoring of native interactions to achieve a target Hamiltonian. The flexib…
Measurement of hyperfine structure in the line of Rb
Durgesh Datar, Nikhil Kotibhaskar, Sharath Ananthamurthy +1
We report a precise measurement of hyperfine constants in the line ( state) of the two stable isotopes of Rb. The motivation for the work is to try…
