Weakly Measured Loops for Quantum Amplitude Amplification: Oracle Savings and Adaptive Search with Unknown Target Probability
Wang Fang, Chris Heunen
We present a family of quantum amplitude amplification algorithms that interleave ordinary Grover rotations with tunable weak measurements in loops. A successful measurement yields…
Unitary Synthesis with Near-Optimal T-Count for Near-Clifford Unitaries
Wang Fang, Chris Heunen, Qisheng Wang
We present an approach to unitary synthesis that implements an arbitrary -qubit unitary operator by a Clifford+T circuit with T-count $\widetilde{O}(2^n d_F^{\mathcal{C}}(U)…
Free Quantum Computing
Jacques Carette, Chris Heunen, Robin Kaarsgaard +2
Quantum computing improves substantially on known classical algorithms for various important problems, but the nature of the relationship between quantum and classical computing is…
String Diagrams for Defect-Based Surface Code Computing
Mateusz Kupper, Dominic Horsman, Chris Heunen +1
Surface codes are a popular choice for implementing fault-tolerant quantum computing. Two-qubit gates may be realised in these codes using only nearest-neighbour interactions, eith…
Hadamard-Pi: Equational Quantum Programming
Wang Fang, Chris Heunen, Robin Kaarsgaard
Quantum computing offers advantages over classical computation, yet the precise features that set the two apart remain unclear. In the standard quantum circuit model, adding a 1-qu…
A Brief Review of Quantum Machine Learning for Financial Services
Mina Doosti, Petros Wallden, Conor Brian Hamill +3
This review paper examines state-of-the-art algorithms and techniques in quantum machine learning with potential applications in finance. We discuss QML techniques in supervised le…
