Parallel Multi-Pair Entanglement of Trapped Ion Qubits

Trapped ions are considered a top contender for realizing a quantum computer, due to their dense qubit-to-qubit connectivity, high gate fidelities, long coherence times, and clean state detection. However, trapped-ion quantum computers offer limited gate speeds in long ion chains. In this talk, we present a novel approach for implementing multiple entangling gates in parallel using pulse shaping, with negligible overhead when compared to a single entangling gate implementation. Our methodology advances gate-pulse synthesis and dramatically simplifies calibration overhead for extended ion chains. These demonstrate parallel gates in a 5-qubit trapped-ion quantum computer, for 1-regular, star, and linear-nearest-neighbor graph patterns, and show clear speed ups over a rudimentary serial implementation.
