Warm-Started QAOA with Custom Mixers Provably Converges and Computationally Beats Goemans-Williamson's Max-Cut at Low Circuit Depths
Reuben Tate, Jai Moondra, Bryan Gard +2
We generalize the Quantum Approximate Optimization Algorithm (QAOA) of Farhi et al. (2014) to allow for arbitrary separable initial states with corresponding mixers such that the s…
A Classically Efficient Quantum Scalable Fermi-Hubbard Benchmark
Bryan T. Gard, Adam M. Meier
In order to quantify the relative performance of different testbed quantum computing devices, it is useful to benchmark them using a common protocol. While some benchmarks rely on…
Transport-enabled entangling gate for trapped ions
Holly N. Tinkey, Craig R. Clark, Brian C. Sawyer +1
We implement a two-qubit entangling Mølmer-Sørensen interaction by transporting two co-trapped ions through a stationary, bichromatic optical beam within a s…
High-Fidelity Bell-State Preparation with Ca Optical Qubits
Craig R. Clark, Holly N. Tinkey, Brian C. Sawyer +10
Entanglement generation in trapped-ion systems has relied thus far on two distinct but related geometric phase gate techniques: Molmer-Sorensen and light-shift gates. We recently p…
Quantum process tomography of a Mølmer-Sørensen gate via a global beam
Holly N Tinkey, Adam M Meier, Craig R Clark +2
We present a framework for quantum process tomography of two-ion interactions that leverages modulations of the trapping potential and composite pulses from a global laser beam to…
