Quantum dot - photonic crystal cavity
The focus of our effort has been to develop quantum information processing technologies based on a solid-state cavity QED platform consisting of quantum dots in photonic crystals. The main goals that we have accomplished include: 1. Study of the ultrafast dynamics of the quantum dot-cavity QED system [Majumdar et al., Phys. Rev. A, 2012], and ultrafast switching between two single photon pulses...
متن کاملFast, High Fidelity Quantum Dot Spin Initialization without a Strong Magnetic Field by Two-Photon Processes
Recent demonstrations of cavity quantum electrodynamics (QED) effects with semiconductor quantum dots (QDs) coupled to microcavities [1, 2, 3, 4, 5] show that these systems are robust and scalable platforms for quantum information science. The QD-cavity QED experiments performed so far treat each QD as a two-level quantum system consisting of a ground state and the single exciton excited state....
متن کاملStrong Coupling Cavity QED with Gate-Defined Double Quantum Dots Enabled by a High Impedance Resonator
The strong coupling limit of cavity quantum electrodynamics (QED) implies the capability of a matterlike quantum system to coherently transform an individual excitation into a single photon within a resonant structure. This not only enables essential processes required for quantum information processing but also allows for fundamental studies of matter-light interaction. In this work, we demons...
متن کاملPhoton-mediated electron transport in hybrid circuit-QED
We investigate photon-mediated transport processes in a hybrid circuit-QED structure consisting of two double quantum dots coupled to a common microwave cavity. Under suitable resonance conditions, electron transport in one double quantum dot is facilitated by the transport in the other dot via photon-mediated processes through the cavity. We calculate the average current in the quantum dots, t...
متن کاملAnalytical Investigation of Frequency Behavior in Tunnel Injection Quantum Dot VCSEL
The frequency behavior of the tunnel injection quantum dot vertical cavitysurface emitting laser (TIQD-VCSEL) is investigated by using an analyticalnumericalmethod on the modulation transfer function. The function is based on therate equations and is decomposed into components related to different energy levelsinside the quantum dot and injection well. In this way, the effect of the tunnelingpr...
