Self-calibrating tomography for multi-dimensional systems
Nicolás Quesada, Agata M. Brańczyk, Daniel F. V. James
We present a formalism for self-calibrating tomography of arbitrary dimensional systems. Self-calibrating quantum state tomography was first introduced in the context of qubits, an…
Fourier Transform Quantum State Tomography
Mohammadreza Mohammadi, Agata M. Branczyk, Daniel F. V. James
We propose a technique for performing quantum state tomography of photonic polarization-encoded multi-qubit states. Our method uses a single rotating wave plate, a polarizing beam…
Quantum properties and dynamics of X states
Nicolás Quesada, Asma Al-Qasimi, Daniel F. V. James
X states are a broad class of two-qubit density matrices that generalize many states of interest in the literature. In this work, we give a comprehensive account of various quantum…
A proposal for a scalable universal bosonic simulator using individually trapped ions
Hoi-Kwan Lau, Daniel F. V. James
We describe a possible architecture to implement a universal bosonic simulator (UBS) using trapped ions. Single ions are confined in individual traps, and their motional states rep…
An excitation-dependent four-level model for quantum entanglement in photosynthetic systems
Chi-Han Chang, Agata M. Branczyk, Gregory D. Scholes +1
We model energy transfer between two coupled four-level chromophores with arbitrarily spaced energy levels. Our analysis takes into account the crucial---yet often ignored---proces…
