Dynamical decoupling sequences for multi-qubit dephasing suppression and long-time quantum memory
Gerardo A. Paz-Silva, Seung-Woo Lee, Todd J. Green +1
We consider a class of multi-qubit dephasing models that combine classical noise sources and linear coupling to a bosonic environment, and are controlled by arbitrary sequences of…
Phase-modulated decoupling and error suppression in qubit-oscillator systems
T. J. Green, M. J. Biercuk
We present a scheme designed to suppress the dominant source of infidelity in entangling gates between quantum systems coupled through intermediate bosonic oscillator modes. Such s…
Experimental noise filtering by quantum control
A. Soare, H. Ball, D. Hayes +6
Instabilities due to extrinsic interference are routinely faced in systems engineering, and a common solution is to rely on a broad class of techniques in orde…
Robustness of composite pulses to time-dependent control noise
Chingiz Kabytayev, Todd J. Green, Kaveh Khodjasteh +3
We study the performance of composite pulses in the presence of time-varying control noise on a single qubit. These protocols, originally devised only to correct for static, system…
Arbitrary quantum control of qubits in the presence of universal noise
Todd J. Green, Jarrah Sastrawan, Hermann Uys +1
In this manuscript we address the problem of deriving \emph{analytic} expressions for calculating universal decoherence-induced errors in qubits undergoing arbitrary, unitary, time…
Long-time Low-latency Quantum Memory by Dynamical Decoupling
Kaveh Khodjasteh, Jarrah Sastrawan, David Hayes +3
Quantum memory is a central component for quantum information processing devices, and will be required to provide high-fidelity storage of arbitrary states, long storage times and…
High-order noise filtering in nontrivial quantum logic gates
Todd Green, Hermann Uys, Michael J. Biercuk
Treating the effects of a time-dependent classical dephasing environment during quantum logic operations poses a theoretical challenge, as the application of non-commuting control…
