We describe two distinct applications of quantum dots [1-3] from a quantum transport perspective. In the first part, we bring in a Bayesian viewpoint to the analysis of clocks, specifically taking the Salecker Wigner clock formulation [4] and explore a novel set up to estimate the tunneling time [1] between electrons in a contact and a quantum dot weakly coupled to it. Using the exponential tunneling distribution as priors for clocks, we analyze the case of a single precessing spin in a quantum dot.

Abstract: Is your work new, and is it useful? Who else knows about it, and how? These are fundamental questions to whether or not a patent can be obtained. Is your idea abstract or tangible? Can software be patented, and if so how? This lecture will cover the criteria for patentability, the process for obtaining a patent and the timeline, and the costs and strategies involved in developing a patent portfolio.

Searching for p+ip topological superconducting (SC) state has become a fascinating subject in condensed matter physics, as a dream application awaits in topological quantum computation. In this talk, I will report the theoretical discovery of a p+ip SC ground state (coexisting with ferromagnetic order) in honeycomb lattice Hubbard model with infinite repulsive interaction at low doping(< 0.2), by using both the state-of-art Grassmann tensor product state(GTPS) approach and a quantum field theory approach.

Three coupled harmonic oscillators with an interaction given by the trilinear Hamiltonian $a^{\dagger} b c + a b^{\dagger} c^{\dagger}$ can describe a wide range of physical processes. In this talk I will show how we implement the trilinear Hamiltonian utilizing a chain of three $^{171}$Yb$^+$ ions in a linear Paul trap.

Semiconductor electron pump devices have shown promise for current standards due to their high accuracy current transport [1]. Further to this, at higher fields and frequencies these pumps demonstrate excitation states corresponding to energies in the microwave range [2]. This suggests possible applications in microwave and THz photonics, an emerging field with applications spanning from quantum information processing to medical imaging.

Quantum information processing (QIP) has been identified as one of the key future technologies that are crucial for communication, cryptography, computing, complex-system simulation, metrology, artificial intelligence and national security. Quantum control, on the other hand, provides a powerful tool to analyze and improve the physical performances of different QIP devices.

One of the remarkable recent discoveries in information science is that quantum mechanics can lead to efficient solutions for problems that are intractable on conventional classical computers.
