High-fidelity Two-qubit Gates and Noise Spectroscopy with Superconducting Qubits
… a fast adiabatic control and spin-locking noise spectroscopy---by incorporating the impact of higher energy levels of a qubit and coupler. Specifically, we harness the higher levels of a coupler as a resource to cancel out an unwanted ZZ interaction between qubits, and thereby …

Coherence characterization with a superconducting flux qubit through NMR approaches
… spectroscopy method is presented, where the spin-locking technique is employed to extract noise information by measuring the driven-evolution longitudinal relaxation. This technique shows improved accuracy over other methods, due to its insensitivity to low-frequency noise. Spectral …

NMR studies of acetylene absorbed on supported platinum catalysts
… Measurements from 77""K to 158°K of the spin-lattice relaxation behavior of carbon-13 reveal multiple-exponential behavior. Calculations rule out an anisotropic T 1 as an explanation for the multiple-exponential behavior. Carbon-proton SEDOR measurements indicate that each time constant, …

New methods for dynamic nuclear polarization in insulating solids : the Overhauser effect and time domain techniques
… including the nuclear orientation via electron spin locking (NOVEL) and integrated solid effect (ISE) at magnetic fields ranging from 0.35 T to 3.35 T. The NOVEL pulse sequence relies on a matching condition between the nuclear Larmor frequency and the electron Rabi frequency, resulting in a …

High Fidelity Universal Gates Performed on a Continuously-Decoupled Coherence Enhanced Transmon Qubit
<p>Decoherence is the primary limiting factor for the utility of modern qubits and qubit networks; most chiefly, pure dephasing which limits the operational time any gate-sequence can produce a high-fidelity result. In this dissertation, I present the results of my experiment, performing fast, high …

Tight-binding simulations of random alloy and strong spin-orbit effects in InAs/GaBiAs quantum dot molecules
… quantum dots (QDs), which have long hole-spin coherence times and are amenable to optical control schemes, have long been explored as building blocks for qubit architectures. One such design consists of vertically stacking two QDs to create a quantum dot molecule (QDM). The two dots can be …

Designing, Modeling, and Optimizing Transactional Data Structures
… to 4x better) as it decreases the overhead of spin locking during commit, in terms of cache misses, blocking of lock holders, and CAS operations. Remote Inval- idation (RInval) applies the same idea of RTC on invalidation based STM algorithms. Furthermore, it allows more concurrency by …
