As quantum processors become increasingly refined, benchmarking them in useful ways becomes a critical topic. Traditional approaches to quantum tomography, such as state tomography, suffer from self-consistency problems, requiring either perfectly pre-calibrated operations or measurements. This problem has recently been tackled by explicitly self-consistent protocols such as randomized...
Quantum beat spectroscopy is an experimental method that utilizes the interference between energetic transitions in atoms and molecules to detect energy level structures, dipole moments and resonances in complex molecules to a high degree of accuracy. Typically these processes require a high degree of time sensitivity however, in this work we show that specific, off-resonant,...
We consider a three-dimensional system where a relativistic electron moves under a constant magnetic field and a linear electric field parallel to the magnetic field above the z=0 plane and antiparallel below the plane. We use the Dirac equation and perturbation theory to determine analytically the first order relativistic correction to the Landau levels under the above static fields.
The quantum kicked top is a fundamental model used to study the emergence of classically chaotic behaviour in periodically driven systems arising from a quantum mechanical origin. Experimentally realized as a many-body ensemble of interacting qubits, the kicked top has allowed insight into how nonlinear features in the classical picture, such as a mixed phase space and bifurcation dynamics,...
We investigate a Bose-Einstein condensate (BEC) as a gravitational wave detector, and study its sensitivity by optimizing the properties of the condensate and the measurement duration. We show that detecting kilohertz gravitational waves is limited by current experimental techniques in squeezing BEC phonons. Future improvements in technology to squeeze BEC states can make them competitive...
