Phase locking nuclear spins in silicon with spin-orbit coupling
Habitamu Y. Walelign, Manas Ranjan Sahu, John M. Nichol
Because they have such long coherence times, nuclear spins have extraordinary potential for use in quantum information processing devices. However, coherent nuclear spin control ge…
Stochastic trajectories and excursions in a double quantum dot system
Guilherme Fiusa, Pedro E. Harunari, Alberto J. B. Rosal +2
We investigate the trajectory-level stochastic dynamics of a double quantum dot system using the formalism of stochastic excursions. An excursion is a sub-trajectory that begins wh…
Measuring and correcting nanosecond pulse distortions in quantum-dot spin qubits
Jiheng Duan, Fernando Torres-Leal, John M. Nichol
Gate-defined semiconductor quantum dots utilize fast electrical control to manipulate spin and charge states of individual electrons. Electrical pulse distortions can limit control…
Mitigating Residual Exchange Coupling in Resonant Singlet-Triplet Qubits
Jiheng Duan, Fernando Torres-Leal, John M. Nichol
We propose methods to mitigate single- and two-qubit control errors due to residual exchange coupling in systems of exchange-coupled resonant singlet-triplet qubits. Commensurate d…
Magnetic Field Tolerant Superconducting Spiral Resonators for Circuit QED
M. Medahinne, Y. P. Kandel, S. Thapa Magar +3
We present spiral resonators of thin film niobium (Nb) that exhibit large geometric inductance, high critical magnetic fields and high single photon quality factors. These low loss…
Analog Quantum Simulation of the Dynamics of Open Quantum Systems with Quantum Dots and Microelectronic Circuits
Chang Woo Kim, John M. Nichol, Andrew N. Jordan +1
We introduce a general setup for the analog quantum simulation of the dynamics of open quantum systems based on semiconductor quantum dots electrically connected to a chain of quan…
Stabilization and manipulation of multispin states in quantum-dot time crystals with Heisenberg interactions
Edwin Barnes, John M. Nichol, Sophia E. Economou
A discrete time crystal is a recently discovered non-equilibrium phase of matter that has been shown to exist in disordered, periodically driven Ising spin chains. In this phase, i…
