The Pinnacle Architecture: Reducing the cost of breaking RSA-2048 to 100 000 physical qubits using quantum LDPC codes
Paul Webster, Lucas Berent, Omprakash Chandra +5
The realisation of utility-scale quantum computing inextricably depends on the design of practical, low-overhead fault-tolerant architectures. We introduce the Pinnacle Architectur…
Exploiting Movable Logical Qubits for Lattice Surgery Compilation
Laura S. Herzog, Lucas Berent, Aleksander Kubica +1
Lattice surgery with two-dimensional quantum error correcting codes is among the leading schemes for fault-tolerant quantum computation, motivated by superconducting hardware archi…
Fast surgery for quantum LDPC codes
Nouédyn Baspin, Lucas Berent, Lawrence Z. Cohen
Quantum LDPC codes promise significant reductions in physical qubit overhead compared with topological codes. However, many existing constructions for performing logical operations…
Localized statistics decoding for quantum low-density parity-check codes
Timo Hillmann, Lucas Berent, Armanda O. Quintavalle +3
Quantum low-density parity-check codes are a promising candidate for fault-tolerant quantum computing with considerably reduced overhead compared to the surface code. However, the…
Lattice Surgery Compilation Beyond the Surface Code
Laura S. Herzog, Lucas Berent, Aleksander Kubica +1
Large-scale fault-tolerant quantum computation requires compiling logical circuits into physical operations tailored to a given architecture. Prior work addressing this challenge h…
Automated Synthesis of Fault-Tolerant State Preparation Circuits for Quantum Error Correction Codes
Tom Peham, Ludwig Schmid, Lucas Berent +2
A central ingredient in fault-tolerant quantum algorithms is the initialization of a logical state for a given quantum error-correcting code from a set of noisy qubits. A scheme th…
