Benchmarking exchange-only control of a 48-spin singlet manifold
HRL Quantum Team, Microsoft Collaborators, : +125
Exchange-only quantum computing benefits from high fidelity and straightforward control afforded by the exchange interaction. However, independently controllable qubits must be enc…
Analytical Stackelberg Resource Allocation in Sequential Attacker--Defender Games
Azhar Iqbal, James M. Chappell, Derek Abbott
We develop an analytical Stackelberg game framework for optimal resource allocation in a sequential attacker--defender setting with a finite set of assets and probabilistic attacks…
Resolving game theoretical dilemmas with quantum states
Azhar Iqbal, James M. Chappell, Claudia Szabo +1
We present a new framework for creating a quantum version of a classical game, based on Fine's theorem. This theorem shows that for a given set of marginals, a system of Bell's ine…
A flexible design platform for Si/SiGe exchange-only qubits with low disorder
Wonill Ha, Sieu D. Ha, Maxwell D. Choi +14
Spin-based silicon quantum dots are an attractive qubit technology for quantum information processing with respect to coherence time, control, and engineering. Here we present an e…
Hilbert's forgotten equation, the equivalence principle and velocity dependence of free fall
David L. Berkahn, James M. Chappell, Derek Abbott
Referring to the behavior of accelerating objects in special relativity, and applying the principle of equivalence, one expects that the coordinate acceleration of point masses und…
Generalizing the Lorentz transformations
James M. Chappell, David L. Berkahn, Nicolangelo Iannella +3
In this paper we develop a framework allowing a natural extension of the Lorentz transformations. To begin, we show that by expanding conventional four-dimensional spacetime to eig…
