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…

Maximal Simplification of Polyhedral Reductions

Louis Narmour, Tomofumi Yuki, Sanjay Rajopadhye

Reductions combine collections of input values with an associative and often commutative operator to produce collections of results. When the same input value contributes to multip…

Simplification of Polyhedral Reductions in Practice

Louis Narmour, Ryan Job, Tomofumi Yuki +1

Reductions combine collections of inputs with an associative (and here, also commutative) operator to produce collections of outputs. When the same value contributes to multiple ou…
