Fast Microwave-free State Preparation and Measurement of Superconducting Qubits
R. Abraham, F. Amet, P. Anderson +212
Fast, high-fidelity, scalable state preparation and measurement is critical to the realization of a quantum computing system. The state-of-the-art methods for preparation and reado…
Towards Quantum Gates with Wide Operating Margins
Ryan J. Epstein
Scaling up quantum computing hardware is hindered by the narrow operating margins of current quantum components. Here, we introduce a composite qubit and gate scheme that achieves…
Low-Weight Pauli Hamiltonian Sequences for Noise-Resilient Quantum Gates
Ryan J. Epstein
A simple protocol based on low-weight Pauli Hamiltonians is introduced for performing quantum gates that are robust to control noise. Gates are implemented by an adiabatic sequence…
High Saturation Power Josephson Parametric Amplifier with GHz Bandwidth
O. Naaman, D. G. Ferguson, R. J. Epstein
We present design and simulation of a Josephson parametric amplifier with bandwidth exceeding 1.6 GHz, and with high saturation power approaching -90 dBm at a gain of 22.8 dB. An i…
Demonstration of a scalable, multiplexed ion trap for quantum information processing
D. R. Leibrandt, J. Labaziewicz, R. J. Clark +14
A scalable, multiplexed ion trap for quantum information processing is fabricated and tested. The trap design and fabrication process are optimized for scalability to small trap si…
Simplified motional heating rate measurements of trapped ions
R. J. Epstein, S. Seidelin, D. Leibfried +13
We have measured motional heating rates of trapped atomic ions, a factor that can influence multi-ion quantum logic gate fidelities. Two simplified techniques were developed for th…
