How fast can a parent estimate the value of their children? A quantum algorithm for stochastic games
Marien Raat, Merlin Incerti-Medici, James R. Wootton +2
We give a quantum algorithm for stochastic -player games. Their game trees are the expectiminimax trees of classical game search: adversarial layers alternate with chanc…
QPU-scale randomized benchmarking via Bell-pair injection
Haripriya Pettugani, María Aguado-Yáñez, Astryd Park +2
Mirror randomized benchmarking (MRB) is an established technique that provides a global error metric at the scale of a whole QPU. To expand upon this we introduce Mirror Quantum Aw…
Quantum circuit design via dynamic Pauli constraints
James R. Wootton, Merlin Incerti-Medici, Daniel Bultrini +1
We introduce the Motte model, a software-oriented model of quantum computation motivated by the practical constraints of near-term quantum hardware. In this model, gates are specif…
Large-scale implementation of quantum subspace expansion with classical shadows
Laurin E. Fischer, Daniel Bultrini, Ivano Tavernelli +1
Quantum subspace expansion (QSE) offers promising avenues to perform spectral calculations on quantum processors but comes with a large measurement overhead. Informationally comple…
Quantum Brush: A quantum computing-based tool for digital painting
João S. Ferreira, Arianna Crippa, Astryd Park +5
We present Quantum Brush, an open-source digital painting tool that harnesses quantum computing to generate novel artistic expressions. The tool includes four different brushes tha…
Procedural Generation and Games at the Dawn of Fault Tolerant Quantum Computing
Daniel Bultrini, James Wootton
Quantum computers have long been more of a toy for researchers than a tool for solving complex problems. However, recent advances in the field make exploiting the advantages of fau…
A framework of partial error correction for intermediate-scale quantum computers
Nikolaos Koukoulekidis, Samson Wang, Tom O'Leary +3
As quantum computing hardware steadily increases in qubit count and quality, one important question is how to allocate these resources to mitigate the effects of hardware noise. In…
Mixed Quantum-Classical Dynamics for Near Term Quantum Computers
Daniel Bultrini, Oriol Vendrell
Mixed quantum-classical dynamics is a set of methods often used to understand systems too complex to treat fully quantum mechanically. Many techniques exist for full quantum mechan…
The battle of clean and dirty qubits in the era of partial error correction
Daniel Bultrini, Samson Wang, Piotr Czarnik +4
When error correction becomes possible it will be necessary to dedicate a large number of physical qubits to each logical qubit. Error correction allows for deeper circuits to be r…
Unifying and benchmarking state-of-the-art quantum error mitigation techniques
Daniel Bultrini, Max Hunter Gordon, Piotr Czarnik +4
Error mitigation is an essential component of achieving a practical quantum advantage in the near term, and a number of different approaches have been proposed. In this work, we re…
Simple Mitigation Strategy for a Systematic Gate Error in IBMQ
Daniel Bultrini, Max Hunter Gordon, Esperanza López +1
We report the observation and characterisation of a systematic error in the implementation of gates in the IBM quantum computers. The error appears as a consistent shift in o…
