Quantifying the advantages of applying quantum approximate algorithms to portfolio optimisation
Haomu Yuan, Christopher K. Long, Hugo V. Lepage +1
We present a quantum algorithm for portfolio optimisation. Specifically, We present san end-to-end quantum approximate optimisation algorithm to solve the discrete global minimum v…
Charge qubits based on ultra-thin topological insulator films
Kexin Zhang, Hugo V. Lepage, Ying Dong +1
We study how to use the surface states in a BiSe topological insulator ultra-thin film that are affected by finite size effects for the purpose of quantum computing. We…
Pulse-controlled qubit in semiconductor double quantum dots
Aleksander Lasek, Hugo V. Lepage, Kexin Zhang +2
We present a numerically-optimized multipulse framework for the quantum control of a single-electron charge qubit. Our framework defines a set of pulse sequences, necessary for the…
Entanglement generation via power-of-SWAP operations between dynamic electron-spin qubits
Hugo V. Lepage, Aleksander A. Lasek, David R. M. Arvidsson-Shukur +1
Surface acoustic waves (SAWs) can create moving quantum dots in piezoelectric materials. Here we show how electron-spin qubits located on dynamic quantum dots can be entangled. Pre…
Quantum Advantage in Postselected Metrology
David R. M. Arvidsson-Shukur, Nicole Yunger Halpern, Hugo V. Lepage +3
We show that postselection offers a nonclassical advantage in metrology. In every parameter-estimation experiment, the final measurement or the postprocessing incurs some cost. Pos…
Sound-driven single-electron transfer in a circuit of coupled quantum rails
Shintaro Takada, Hermann Edlbauer, Hugo V. Lepage +13
Surface acoustic waves (SAWs) strongly modulate the shallow electric potential in piezoelectric materials. In semiconductor heterostructures such as GaAs/AlGaAs, SAWs can thus be e…
Protocol for Fermionic Positive-Operator-Valued Measures
David R. M. Arvidsson-Shukur, Hugo V. Lepage, Edmund T. Owen +2
In this paper we present a protocol for the implementation of a positive-operator-valued measure (POVM) on massive fermionic qubits. We present methods for implementing non-dispers…
