The Virtuous Cycle of Quantum-Classical Machine Learning
Nenad Tomašev, Jarrod R. McClean, Johannes Bausch
Artificial intelligence and quantum computing have both seen tremendous progress in recent years, opening up new avenues for accelerating scientific discovery. Classical machine le…
Quantum error correction below the surface code threshold
Rajeev Acharya, Laleh Aghababaie-Beni, Igor Aleiner +246
Quantum error correction provides a path to reach practical quantum computing by combining multiple physical qubits into a logical qubit, where the logical error rate is suppressed…
Phase Estimation of Local Hamiltonians on NISQ Hardware
Laura Clinton, Johannes Bausch, Joel Klassen +1
In this work we investigate a binned version of Quantum Phase Estimation (QPE) set out by [Somma 2019] and known as the Quantum Eigenvalue Estimation Problem (QEEP). Specifically,…
The Complexity of Approximating Critical Points of Quantum Phase Transitions
James D. Watson, Johannes Bausch
Phase diagrams chart material properties with respect to one or more external or internal parameters such as pressure or magnetisation; as such, they play a fundamental role in man…
Scalable Benchmarks for Gate-Based Quantum Computers
Arjan Cornelissen, Johannes Bausch, András Gilyén
In the near-term "NISQ"-era of noisy, intermediate-scale, quantum hardware and beyond, reliably determining the quality of quantum devices becomes increasingly important: users nee…
Mitigating Errors in Local Fermionic Encodings
Johannes Bausch, Toby Cubitt, Charles Derby +1
Quantum simulations of fermionic many-body systems crucially rely on mappings from indistinguishable fermions to distinguishable qubits. The non-local structure of fermionic Fock s…
