- Description:
- Superconducting-circuit based platforms are strong contenders in the race to build a quantum computer.While the transmon has had extraordinary success as the leading superconducting qubit modality, there are reasons to believe that other types of qubits could possess relative benefits in terms of noise immunity, anharmonicity, or extensibility. In this...

- Description:
- Future large-scale quantum networks will likely require more efficient on-chip devices for quantum key distribution (QKD) systems that can exploit CMOS manufacturing techniques. QKD systems on chip have been produced in a number of material platforms including silicon, indium phosphide, and a range of hybrid structures. Advanced industrial silicon-electronics manufacturing...

- Description:
- Superconducting qubits are among the leading competitors in the race towards building the first full-fledged quantum computer. Using this platform, researchers have for the first time demonstrated computational capability that is beyond the reach of the current classical machines. (This achievement is nicknamed "Quantum Supremacy".) Up to date, however, the...

- Description:
- Superconducting circuits are electrical circuits fabricated from superconducting materials. Due to the engineered strong interactions and suppressed sensitivity to environmental noise, such systems hold substantial promise as quantum bits, in which quantum information can be stored and manipulated with high fidelity. Over the decades, great efforts have been devoted to...

- Description:
- This thesis contains results in mathematical quantum ergodicity in a probabilistic or a complex analytic setting. For the former, we show that a random orthonormal basis of spherical harmonics is almost surely quantum ergodic, in which the randomness is induced by the generalized Wigner ensemble. For the latter, we show...
