Computing 256-bit elliptic curve discrete logarithms in 26 days on a fault-tolerant trapped-ion quantum computer with 20,000 qubits
Thomas Häner, Felix Tripier, Jacob Young +11
One of the strengths of our recently proposed Walking Cat Architecture for a trapped-ion quantum computer is that it is straightforward to extend and optimize for a specific applic…
Breakeven demonstration of quantum low-density parity-check codes
Edwin Tham, Michael L. Goldman, Shantanu Debnath +8
High-rate quantum low-density parity-check (qLDPC) codes are a leading candidate for fault-tolerant quantum computing. They feature higher encoding rates than planar alternatives s…
Fault-Tolerant Quantum Computing with Trapped Ions: The Walking Cat Architecture
Felix Tripier, Woo Chang Chung, Jacob Young +15
We propose a fault-tolerant quantum computer architecture for trapped-ion devices, which we call the walking cat architecture. Our blueprint includes a compiler, a detailed descrip…
Extremum seeking control of quantum gates
Erfan Abbasgholinejad, Haoqin Deng, John Gamble +4
To be useful for quantum computation, gate operations must be maintained at high fidelities over long periods of time. In addition to decoherence, slow drifts in control hardware l…
