Stream Decoding with Confidence Scores at Room and Cryogenic Temperatures
Maries Tahaab, Tim Chan, James Kirkman +1
In fault-tolerant quantum computing, fast and accurate decoding is crucial. Snowflake is a decoder for the surface code that runs in a streaming fashion. In this paper, we implemen…
A route to damage tolerance exceeding in shuttling-equipped quantum processors
Quinten Eggerickx, Simon C. Benjamin
This is a short study of an approach offering high tolerance to damage (i.e. defects or 'drop outs') in solid state fault-tolerant quantum computing. Our method is primarily aimed…
Nanostructure modelling with early fault tolerant quantum computers
Zhu Sun, Christian Binder, Balint Koczor +1
Semiconductor nanostructures are central to many developing technologies. Notably, double quantum dots are especially important for semiconductor spin-qubit architectures, quantum…
Error mitigation for logical circuits using decoder confidence
Maria Dincă, Tim Chan, Simon C. Benjamin
Fault-tolerant quantum computers use decoders to monitor for errors and find a plausible correction. A decoder may provide a \emph{decoder confidence score} (DCS) to gauge its succ…
Erasure conversion for singlet-triplet spin qubits enables high-performance shuttling-based quantum error correction
Adam Siegel, Simon Benjamin
Fast and high fidelity shuttling of spin qubits has been demonstrated in semiconductor quantum dot devices. Several architectures based on shuttling have been proposed; it has been…
Artificial Intelligence for Quantum Computing
Yuri Alexeev, Marwa H. Farag, Taylor L. Patti +25
Artificial intelligence (AI) advancements over the past few years have had an unprecedented and revolutionary impact across everyday application areas. Its significance also extend…
Low Depth Phase Oracle Using a Parallel Piecewise Circuit
Zhu Sun, Gregory Boyd, Zhenyu Cai +7
We explore the important task of applying a phase to a computational basis state . The closely related task of rotating a target qubit by an angle…
Robustness of electron charge shuttling: Architectures, pulses, charge defects and noise thresholds
Minjun Jeon, Simon C. Benjamin, Andrew J. Fisher
In semiconductor-based quantum technologies, the capability to shuttle charges between components is profoundly enabling. We numerically simulated various "conveyor-belt" shuttling…
Ab initio modelling of quantum dot qubits: Coupling, gate dynamics and robustness versus charge noise
Hamza Jnane, Simon C Benjamin
Electron spins in semiconductor devices are highly promising building blocks for quantum processors (QPs). Commercial semiconductor foundries can create QPs using the same processe…
Actis: A Strictly Local Union-Find Decoder
Tim Chan, Simon C. Benjamin
Fault-tolerant quantum computing requires classical hardware to perform the decoding necessary for error correction. The Union-Find decoder is one of the best candidates for this.…
Grid-based methods for chemistry simulations on a quantum computer
Hans Hon Sang Chan, Richard Meister, Tyson Jones +2
First quantized, grid-based methods for chemistry modelling are a natural and elegant fit for quantum computers. However, it is infeasible to use today's quantum prototypes to expl…
